-# Azure SDK for Go
-
-[![godoc](https://godoc.org/github.com/Azure/azure-sdk-for-go?status.svg)](https://godoc.org/github.com/Azure/azure-sdk-for-go)
-[![Build Status](https://travis-ci.org/Azure/azure-sdk-for-go.svg?branch=master)](https://travis-ci.org/Azure/azure-sdk-for-go)
-[![Go Report Card](https://goreportcard.com/badge/github.com/Azure/azure-sdk-for-go)](https://goreportcard.com/report/github.com/Azure/azure-sdk-for-go)
-
-azure-sdk-for-go provides Go packages for managing and using Azure services. It has been
-tested with Go 1.8, 1.9 and 1.10.
-
-To be notified about updates and changes, subscribe to the [Azure update
-feed](https://azure.microsoft.com/updates/).
-
-Users of the SDK may prefer to jump right in to our samples repo at
-[github.com/Azure-Samples/azure-sdk-for-go-samples][samples_repo].
-
-### Build Details
-
-Most packages in the SDK are generated from [Azure API specs][azure_rest_specs]
-using [Azure/autorest.go][] and [Azure/autorest][]. These generated packages
-depend on the HTTP client implemented at [Azure/go-autorest][].
-
-[azure_rest_specs]: https://github.com/Azure/azure-rest-api-specs
-[Azure/autorest]: https://github.com/Azure/autorest
-[Azure/autorest.go]: https://github.com/Azure/autorest.go
-[Azure/go-autorest]: https://github.com/Azure/go-autorest
-
-The SDK codebase adheres to [semantic versioning](https://semver.org) and thus
-avoids breaking changes other than at major (x.0.0) releases. However,
-occasionally Azure API fixes require breaking updates within an individual
-package; these exceptions are noted in release changelogs.
-
-To more reliably manage dependencies like the Azure SDK in your applications we
-recommend [golang/dep](https://github.com/golang/dep).
-
-# Install and Use:
-
-### Install
-
-```sh
-$ go get -u github.com/Azure/azure-sdk-for-go/...
-```
-
-or if you use dep, within your repo run:
-
-```sh
-$ dep ensure -add github.com/Azure/azure-sdk-for-go
-```
-
-If you need to install Go, follow [the official instructions](https://golang.org/dl/).
-
-### Use
-
-For complete examples of many scenarios see [Azure-Samples/azure-sdk-for-go-samples][samples_repo].
-
-1. Import a package from the [services][services_dir] directory.
-2. Create and authenticate a client with a `New*Client` func, e.g.
-   `c := compute.NewVirtualMachinesClient(...)`.
-3. Invoke API methods using the client, e.g. `c.CreateOrUpdate(...)`.
-4. Handle responses.
-
-[services_dir]: https://github.com/Azure/azure-sdk-for-go/tree/master/services
-
-For example, to create a new virtual network (substitute your own values for
-strings in angle brackets):
-
-Note: For more on authentication and the `Authorizer` interface see [the next
-  section](#authentication).
-
-```go
-package main
-
-import (
-	"context"
-	"github.com/Azure/azure-sdk-for-go/services/network/mgmt/2017-09-01/network"
-	"github.com/Azure/go-autorest/autorest/azure/auth"
-	"github.com/Azure/go-autorest/autorest/to"
-)
-
-func main() {
-	vnetClient := network.NewVirtualNetworksClient("<subscriptionID>")
-	authorizer, err := auth.NewAuthorizerFromEnvironment()
-
-	if err == nil {
-		vnetClient.Authorizer = authorizer
-	}
-
-	vnetClient.CreateOrUpdate(context.Background(),
-		"<resourceGroupName>",
-		"<vnetName>",
-		network.VirtualNetwork{
-			Location: to.StringPtr("<azureRegion>"),
-			VirtualNetworkPropertiesFormat: &network.VirtualNetworkPropertiesFormat{
-				AddressSpace: &network.AddressSpace{
-					AddressPrefixes: &[]string{"10.0.0.0/8"},
-				},
-				Subnets: &[]network.Subnet{
-					{
-						Name: to.StringPtr("<subnet1Name>"),
-						SubnetPropertiesFormat: &network.SubnetPropertiesFormat{
-							AddressPrefix: to.StringPtr("10.0.0.0/16"),
-						},
-					},
-					{
-						Name: to.StringPtr("<subnet2Name>"),
-						SubnetPropertiesFormat: &network.SubnetPropertiesFormat{
-							AddressPrefix: to.StringPtr("10.1.0.0/16"),
-						},
-					},
-				},
-			},
-		})
-}
-```
-
-### Authentication
-
-Most SDK operations require an OAuth token for authentication and authorization. These are
-made available in the Go SDK For Azure through types implementing the `Authorizer` interface.
-You can get one from Azure Active Directory using the SDK's
-[authentication](https://godoc.org/github.com/Azure/go-autorest/autorest/azure/auth) package. The `Authorizer` returned  should
-be set as the authorizer for the resource client, as shown in the [previous section](#use).
-
-You can get an authorizer in the following ways:
-1. From the **Environment**:
-  - Use `auth.auth.NewAuthorizerFromEnvironment()`. This call will try to get an authorizer based on the environment
-variables with different types of credentials in the following order:
-    1. **Client Credentials**: Uses the AAD App Secret for auth.
-      - `AZURE_TENANT_ID`: Specifies the Tenant to which to authenticate.
-      - `AZURE_CLIENT_ID`: Specifies the app client ID to use.
-      - `AZURE_CLIENT_SECRET`: Specifies the app secret to use.
-    2. **Client Certificate**: Uses a certificate that was configured on the AAD Service Principal.
-      - `AZURE_TENANT_ID`: Specifies the Tenant to which to authenticate.
-      - `AZURE_CLIENT_ID`: Specifies the app client ID to use.
-      - `AZURE_CERTIFICATE_PATH`: Specifies the certificate Path to use.
-      - `AZURE_CERTIFICATE_PASSWORD`: Specifies the certificate password to use.
-    3. **Username Pasword**: Uses a username and a password for auth. This is not recommended. Use `Device Flow` Auth instead for user interactive acccess.
-      - `AZURE_TENANT_ID`: Specifies the Tenant to which to authenticate.
-      - `AZURE_CLIENT_ID`: Specifies the app client ID to use.
-      - `AZURE_USERNAME`: Specifies the username to use.
-      - `AZURE_PASSWORD`: Specifies the password to use.
-    4. **MSI**: Only available for apps running in Azure. No configuration needed as it leverages the fact that the app is running in Azure. See [Azure Managed Service Identity](https://docs.microsoft.com/en-us/azure/active-directory/msi-overview).
-
-  - Optionally, the following environment variables can be defined:
-    - `AZURE_ENVIRONMENT`: Specifies the Azure Environment to use. If not set, it defaults to `AzurePublicCloud`. (Not applicable to MSI based auth)
-    - `AZURE_AD_RESOURCE`: Specifies the AAD resource ID to use. If not set, it defaults to `ResourceManagerEndpoint`which allows management operations against Azure Resource Manager.
-
-2. From an **Auth File**:
- - Create a service principal and output the file content using `az ad sp create-for-rbac --sdk-auth` from the Azure CLI.For more details see [az ad sp](https://docs.microsoft.com/en-us/cli/azure/ad/sp).
- - Set environment variable `AZURE_AUTH_LOCATION` for finding the file.
- - Use `auth.NewAuthorizerFromFile()` for getting the `Authorizer` based on the auth file.
-
-3. From **Device Flow** by configuring `auth.DeviceFlowConfig` and calling the `Authorizer()` method.
-
-Note: To authenticate you first need to create a service principal in Azure. To create a new service principal, run
-`az ad sp create-for-rbac -n "<app_name>"` in the
-[azure-cli](https://github.com/Azure/azure-cli). See
-[these docs](https://docs.microsoft.com/cli/azure/create-an-azure-service-principal-azure-cli?view=azure-cli-latest)
-for more info. Copy the new principal's ID, secret, and tenant ID for use in your app.
-
-Alternatively, if your apps are running in Azure, you can now leverage the [Managed Service Identity](https://docs.microsoft.com/en-us/azure/active-directory/msi-overview).
-
-# Versioning
-
-azure-sdk-for-go provides at least a basic Go binding for every Azure API. To
-provide maximum flexibility to users, the SDK even includes previous versions of
-Azure APIs which are still in use. This enables us to support users of the
-most updated Azure datacenters, regional datacenters with earlier APIs, and
-even on-premises installations of Azure Stack.
-
-**SDK versions** apply globally and are tracked by git
-[tags](https://github.com/Azure/azure-sdk-for-go/tags). These are in x.y.z form
-and generally adhere to [semantic versioning](https://semver.org) specifications.
-
-**Service API versions** are generally represented by a date string and are
-tracked by offering separate packages for each version. For example, to choose the
-latest API versions for Compute and Network, use the following imports:
-
-```go
-import (
-    "github.com/Azure/azure-sdk-for-go/services/compute/mgmt/2017-12-01/compute"
-    "github.com/Azure/azure-sdk-for-go/services/network/mgmt/2017-09-01/network"
-)
-```
-
-Occasionally service-side changes require major changes to existing versions.
-These cases are noted in the changelog.
-
-All avilable services and versions are listed under the `services/` path in
-this repo and in [GoDoc][services_godoc].  Run `find ./services -type d
--mindepth 3` to list all available service packages.
-
-[services_godoc]:       https://godoc.org/github.com/Azure/azure-sdk-for-go/services
-
-### Profiles
-
-Azure **API profiles** specify subsets of Azure APIs and versions. Profiles can provide:
-
-* **stability** for your application by locking to specific API versions; and/or
-* **compatibility** for your application with Azure Stack and regional Azure datacenters.
-
-In the Go SDK, profiles are available under the `profiles/` path and their
-component API versions are aliases to the true service package under
-`services/`. You can use them as follows:
-
-```go
-import "github.com/Azure/azure-sdk-for-go/profiles/2017-03-09/compute/mgmt/compute"
-import "github.com/Azure/azure-sdk-for-go/profiles/2017-03-09/network/mgmt/network"
-import "github.com/Azure/azure-sdk-for-go/profiles/2017-03-09/storage/mgmt/storage"
-```
-
-The 2017-03-09 profile is the only one currently available and is for use in
-hybrid Azure and Azure Stack environments. More profiles are under development.
-
-In addition to versioned profiles, we also provide two special profiles
-`latest` and `preview`. These *always* include the most recent respective stable or
-preview API versions for each service, even when updating them to do so causes
-breaking changes. That is, these do *not* adhere to semantic versioning rules.
-
-The `latest` and `preview` profiles can help you stay up to date with API
-updates as you build applications. Since they are by definition not stable,
-however, they **should not** be used in production apps. Instead, choose the
-latest specific API version (or an older one if necessary) from the `services/`
-path.
-
-As an example, to automatically use the most recent Compute APIs, use one of
-the following imports:
-
-```go
-import "github.com/Azure/azure-sdk-for-go/profiles/latest/compute/mgmt/compute"
-import "github.com/Azure/azure-sdk-for-go/profiles/preview/compute/mgmt/compute"
-```
-
-## Inspecting and Debugging
-
-All clients implement some handy hooks to help inspect the underlying requests being made to Azure.
-
-- `RequestInspector`: View and manipulate the go `http.Request` before it's sent
-- `ResponseInspector`: View the `http.Response` received
-
-Here is an example of how these can be used with `net/http/httputil` to see requests and responses.
-
-```go
-
-vnetClient := network.NewVirtualNetworksClient("<subscriptionID>")
-vnetClient.RequestInspector = LogRequest()
-vnetClient.ResponseInspector = LogResponse()
-
-...
-
-func LogRequest() autorest.PrepareDecorator {
-	return func(p autorest.Preparer) autorest.Preparer {
-		return autorest.PreparerFunc(func(r *http.Request) (*http.Request, error) {
-			r, err := p.Prepare(r)
-			if err != nil {
-				log.Println(err)
-			}
-			dump, _ := httputil.DumpRequestOut(r, true)
-			log.Println(string(dump))
-			return r, err
-		})
-	}
-}
-
-func LogResponse() autorest.RespondDecorator {
-	return func(p autorest.Responder) autorest.Responder {
-		return autorest.ResponderFunc(func(r *http.Response) error {
-			err := p.Respond(r)
-			if err != nil {
-				log.Println(err)
-			}
-			dump, _ := httputil.DumpResponse(r, true)
-			log.Println(string(dump))
-			return err
-		})
-	}
-}
-```

-
-Package go-autorest provides an HTTP request client for use with [Autorest](https://github.com/Azure/autorest.go)-generated API client packages.
-
-An authentication client tested with Azure Active Directory (AAD) is also
-provided in this repo in the package
-`github.com/Azure/go-autorest/autorest/adal`.  Despite its name, this package
-is maintained only as part of the Azure Go SDK and is not related to other
-"ADAL" libraries in [github.com/AzureAD](https://github.com/AzureAD).
-
-## Overview
-
-Package go-autorest implements an HTTP request pipeline suitable for use across
-multiple goroutines and provides the shared routines used by packages generated
-by [Autorest](https://github.com/Azure/autorest.go).
-
-The package breaks sending and responding to HTTP requests into three phases: Preparing, Sending,
-and Responding. A typical pattern is:
-
-```go
-  req, err := Prepare(&http.Request{},
-    token.WithAuthorization())
-
-  resp, err := Send(req,
-    WithLogging(logger),
-    DoErrorIfStatusCode(http.StatusInternalServerError),
-    DoCloseIfError(),
-    DoRetryForAttempts(5, time.Second))
-
-  err = Respond(resp,
-		ByDiscardingBody(),
-    ByClosing())
-```
-
-Each phase relies on decorators to modify and / or manage processing. Decorators may first modify
-and then pass the data along, pass the data first and then modify the result, or wrap themselves
-around passing the data (such as a logger might do). Decorators run in the order provided. For
-example, the following:
-
-```go
-  req, err := Prepare(&http.Request{},
-    WithBaseURL("https://microsoft.com/"),
-    WithPath("a"),
-    WithPath("b"),
-    WithPath("c"))
-```
-
-will set the URL to:
-
-```
-  https://microsoft.com/a/b/c
-```
-
-Preparers and Responders may be shared and re-used (assuming the underlying decorators support
-sharing and re-use). Performant use is obtained by creating one or more Preparers and Responders
-shared among multiple go-routines, and a single Sender shared among multiple sending go-routines,
-all bound together by means of input / output channels.
-
-Decorators hold their passed state within a closure (such as the path components in the example
-above). Be careful to share Preparers and Responders only in a context where such held state
-applies. For example, it may not make sense to share a Preparer that applies a query string from a
-fixed set of values. Similarly, sharing a Responder that reads the response body into a passed
-struct (e.g., `ByUnmarshallingJson`) is likely incorrect.
-
-Errors raised by autorest objects and methods will conform to the `autorest.Error` interface.
-
-See the included examples for more detail. For details on the suggested use of this package by
-generated clients, see the Client described below.
-
-## Helpers
-
-### Handling Swagger Dates
-
-The Swagger specification (https://swagger.io) that drives AutoRest
-(https://github.com/Azure/autorest/) precisely defines two date forms: date and date-time. The
-github.com/Azure/go-autorest/autorest/date package provides time.Time derivations to ensure correct
-parsing and formatting.
-
-### Handling Empty Values
-
-In JSON, missing values have different semantics than empty values. This is especially true for
-services using the HTTP PATCH verb. The JSON submitted with a PATCH request generally contains
-only those values to modify. Missing values are to be left unchanged. Developers, then, require a
-means to both specify an empty value and to leave the value out of the submitted JSON.
-
-The Go JSON package (`encoding/json`) supports the `omitempty` tag. When specified, it omits
-empty values from the rendered JSON. Since Go defines default values for all base types (such as ""
-for string and 0 for int) and provides no means to mark a value as actually empty, the JSON package
-treats default values as meaning empty, omitting them from the rendered JSON. This means that, using
-the Go base types encoded through the default JSON package, it is not possible to create JSON to
-clear a value at the server.
-
-The workaround within the Go community is to use pointers to base types in lieu of base types within
-structures that map to JSON. For example, instead of a value of type `string`, the workaround uses
-`*string`. While this enables distinguishing empty values from those to be unchanged, creating
-pointers to a base type (notably constant, in-line values) requires additional variables. This, for
-example,
-
-```go
-  s := struct {
-    S *string
-  }{ S: &"foo" }
-```
-fails, while, this
-
-```go
-  v := "foo"
-  s := struct {
-    S *string
-  }{ S: &v }
-```
-succeeds.
-
-To ease using pointers, the subpackage `to` contains helpers that convert to and from pointers for
-Go base types which have Swagger analogs. It also provides a helper that converts between
-`map[string]string` and `map[string]*string`, enabling the JSON to specify that the value
-associated with a key should be cleared. With the helpers, the previous example becomes
-
-```go
-  s := struct {
-    S *string
-  }{ S: to.StringPtr("foo") }
-```
-

-# AWS SDK for Go
-
-aws-sdk-go is the official AWS SDK for the Go programming language.
-
-Checkout our [release notes](https://github.com/aws/aws-sdk-go/releases) for information about the latest bug fixes, updates, and features added to the SDK.
-
-We [announced](https://aws.amazon.com/blogs/developer/aws-sdk-for-go-2-0-developer-preview/) the Developer Preview for the [v2 AWS SDK for Go](https://github.com/aws/aws-sdk-go-v2). The v2 SDK is available at https://github.com/aws/aws-sdk-go-v2, and `go get github.com/aws/aws-sdk-go-v2` via `go get`. Check out the v2 SDK's [changes and updates](https://github.com/aws/aws-sdk-go-v2/blob/master/CHANGELOG.md), and let us know what you think. We want your feedback. 
-
-## Installing
-
-If you are using Go 1.5 with the `GO15VENDOREXPERIMENT=1` vendoring flag, or 1.6 and higher you can use the following command to retrieve the SDK. The SDK's non-testing dependencies will be included and are vendored in the `vendor` folder.
-
-    go get -u github.com/aws/aws-sdk-go
-
-Otherwise if your Go environment does not have vendoring support enabled, or you do not want to include the vendored SDK's dependencies you can use the following command to retrieve the SDK and its non-testing dependencies using `go get`.
-
-    go get -u github.com/aws/aws-sdk-go/aws/...
-    go get -u github.com/aws/aws-sdk-go/service/...
-
-If you're looking to retrieve just the SDK without any dependencies use the following command.
-
-    go get -d github.com/aws/aws-sdk-go/
-
-These two processes will still include the `vendor` folder and it should be deleted if its not going to be used by your environment.
-
-    rm -rf $GOPATH/src/github.com/aws/aws-sdk-go/vendor

-## Reference Documentation
-
-[`Getting Started Guide`](https://aws.amazon.com/sdk-for-go/) - This document is a general introduction how to configure and make requests with the SDK. If this is your first time using the SDK, this documentation and the API documentation will help you get started. This document focuses on the syntax and behavior of the SDK. The [Service Developer Guide](https://aws.amazon.com/documentation/) will help you get started using specific AWS services.
-
-[`SDK API Reference Documentation`](https://docs.aws.amazon.com/sdk-for-go/api/) - Use this document to look up all API operation input and output parameters for AWS services supported by the SDK. The API reference also includes documentation of the SDK, and examples how to using the SDK, service client API operations, and API operation require parameters.
-
-[`Service Developer Guide`](https://aws.amazon.com/documentation/) - Use this documentation to learn how to interface with an AWS service. These are great guides both, if you're getting started with a service, or looking for more information on a service. You should not need this document for coding, though in some cases, services may supply helpful samples that you might want to look out for.
-
-[`SDK Examples`](https://github.com/aws/aws-sdk-go/tree/master/example) - Included in the SDK's repo are a several hand crafted examples using the SDK features and AWS services.
-
-## Overview of SDK's Packages
-
-The SDK is composed of two main components, SDK core, and service clients.
-The SDK core packages are all available under the aws package at the root of
-the SDK. Each client for a supported AWS service is available within its own
-package under the service folder at the root of the SDK.
-
-  * aws - SDK core, provides common shared types such as Config, Logger,
-    and utilities to make working with API parameters easier.
-
-      * awserr - Provides the error interface that the SDK will use for all
-        errors that occur in the SDK's processing. This includes service API
-        response errors as well. The Error type is made up of a code and message.
-        Cast the SDK's returned error type to awserr.Error and call the Code
-        method to compare returned error to specific error codes. See the package's
-        documentation for additional values that can be extracted such as RequestID.
-
-      * credentials - Provides the types and built in credentials providers
-        the SDK will use to retrieve AWS credentials to make API requests with.
-        Nested under this folder are also additional credentials providers such as
-        stscreds for assuming IAM roles, and ec2rolecreds for EC2 Instance roles.
-
-      * endpoints - Provides the AWS Regions and Endpoints metadata for the SDK.
-        Use this to lookup AWS service endpoint information such as which services
-        are in a region, and what regions a service is in. Constants are also provided
-        for all region identifiers, e.g UsWest2RegionID for "us-west-2".
-
-      * session - Provides initial default configuration, and load
-        configuration from external sources such as environment and shared
-        credentials file.
-
-      * request - Provides the API request sending, and retry logic for the SDK.
-        This package also includes utilities for defining your own request
-        retryer, and configuring how the SDK processes the request.
-
-  * service - Clients for AWS services. All services supported by the SDK are
-    available under this folder.
-
-## How to Use the SDK's AWS Service Clients
-
-The SDK includes the Go types and utilities you can use to make requests to
-AWS service APIs. Within the service folder at the root of the SDK you'll find
-a package for each AWS service the SDK supports. All service clients follows
-a common pattern of creation and usage.
-
-When creating a client for an AWS service you'll first need to have a Session
-value constructed. The Session provides shared configuration that can be shared
-between your service clients. When service clients are created you can pass
-in additional configuration via the aws.Config type to override configuration
-provided by in the Session to create service client instances with custom
-configuration.
-
-Once the service's client is created you can use it to make API requests the
-AWS service. These clients are safe to use concurrently.
-
-## Configuring the SDK
-
-In the AWS SDK for Go, you can configure settings for service clients, such
-as the log level and maximum number of retries. Most settings are optional;
-however, for each service client, you must specify a region and your credentials.
-The SDK uses these values to send requests to the correct AWS region and sign
-requests with the correct credentials. You can specify these values as part
-of a session or as environment variables.
-
-See the SDK's [configuration guide][config_guide] for more information.
-
-See the [session][session_pkg] package documentation for more information on how to use Session
-with the SDK.
-
-See the [Config][config_typ] type in the [aws][aws_pkg] package for more information on configuration
-options.

-
-### Configuring Credentials
-
-When using the SDK you'll generally need your AWS credentials to authenticate
-with AWS services. The SDK supports multiple methods of supporting these
-credentials. By default the SDK will source credentials automatically from
-its default credential chain. See the session package for more information
-on this chain, and how to configure it. The common items in the credential
-chain are the following:
-
-  * Environment Credentials - Set of environment variables that are useful
-    when sub processes are created for specific roles.
-
-  * Shared Credentials file (~/.aws/credentials) - This file stores your
-    credentials based on a profile name and is useful for local development.
-
-  * EC2 Instance Role Credentials - Use EC2 Instance Role to assign credentials
-    to application running on an EC2 instance. This removes the need to manage
-    credential files in production.
-
-Credentials can be configured in code as well by setting the Config's Credentials
-value to a custom provider or using one of the providers included with the
-SDK to bypass the default credential chain and use a custom one. This is
-helpful when you want to instruct the SDK to only use a specific set of
-credentials or providers.
-
-This example creates a credential provider for assuming an IAM role, "myRoleARN"
-and configures the S3 service client to use that role for API requests.
-
-```go
-  // Initial credentials loaded from SDK's default credential chain. Such as
-  // the environment, shared credentials (~/.aws/credentials), or EC2 Instance
-  // Role. These credentials will be used to to make the STS Assume Role API.
-  sess := session.Must(session.NewSession())
-
-  // Create the credentials from AssumeRoleProvider to assume the role
-  // referenced by the "myRoleARN" ARN.
-  creds := stscreds.NewCredentials(sess, "myRoleArn")
-
-  // Create service client value configured for credentials
-  // from assumed role.
-  svc := s3.New(sess, &aws.Config{Credentials: creds})
-```
-
-See the [credentials][credentials_pkg] package documentation for more information on credential
-providers included with the SDK, and how to customize the SDK's usage of
-credentials.
-
-The SDK has support for the shared configuration file (~/.aws/config). This
-support can be enabled by setting the environment variable, "AWS_SDK_LOAD_CONFIG=1",
-or enabling the feature in code when creating a Session via the
-Option's SharedConfigState parameter.
-
-```go
-  sess := session.Must(session.NewSessionWithOptions(session.Options{
-      SharedConfigState: session.SharedConfigEnable,
-  }))
-```
-
-[credentials_pkg]: https://docs.aws.amazon.com/sdk-for-go/api/aws/credentials
-
-### Configuring AWS Region
-
-In addition to the credentials you'll need to specify the region the SDK
-will use to make AWS API requests to. In the SDK you can specify the region
-either with an environment variable, or directly in code when a Session or
-service client is created. The last value specified in code wins if the region
-is specified multiple ways.
-
-To set the region via the environment variable set the "AWS_REGION" to the
-region you want to the SDK to use. Using this method to set the region will
-allow you to run your application in multiple regions without needing additional
-code in the application to select the region.
-
-    AWS_REGION=us-west-2
-
-The endpoints package includes constants for all regions the SDK knows. The
-values are all suffixed with RegionID. These values are helpful, because they
-reduce the need to type the region string manually.
-
-To set the region on a Session use the aws package's Config struct parameter
-Region to the AWS region you want the service clients created from the session to
-use. This is helpful when you want to create multiple service clients, and
-all of the clients make API requests to the same region.
-
-```go
-  sess := session.Must(session.NewSession(&aws.Config{
-      Region: aws.String(endpoints.UsWest2RegionID),
-  }))
-```
-
-See the [endpoints][endpoints_pkg] package for the AWS Regions and Endpoints metadata.
-
-In addition to setting the region when creating a Session you can also set
-the region on a per service client bases. This overrides the region of a
-Session. This is helpful when you want to create service clients in specific
-regions different from the Session's region.
-
-```go
-  svc := s3.New(sess, &aws.Config{
-      Region: aws.String(endpoints.UsWest2RegionID),
-  })
-```
-
-See the [Config][config_typ] type in the [aws][aws_pkg] package for more information and additional
-options such as setting the Endpoint, and other service client configuration options.
-
-[endpoints_pkg]: https://docs.aws.amazon.com/sdk-for-go/api/aws/endpoints/
-
-## Making API Requests
-
-Once the client is created you can make an API request to the service.
-Each API method takes a input parameter, and returns the service response
-and an error. The SDK provides methods for making the API call in multiple ways.
-
-In this list we'll use the S3 ListObjects API as an example for the different
-ways of making API requests.
-
-  * ListObjects - Base API operation that will make the API request to the service.
-
-  * ListObjectsRequest - API methods suffixed with Request will construct the
-    API request, but not send it. This is also helpful when you want to get a
-    presigned URL for a request, and share the presigned URL instead of your
-    application making the request directly.
-
-  * ListObjectsPages - Same as the base API operation, but uses a callback to
-    automatically handle pagination of the API's response.
-
-  * ListObjectsWithContext - Same as base API operation, but adds support for
-    the Context pattern. This is helpful for controlling the canceling of in
-    flight requests. See the Go standard library context package for more
-    information. This method also takes request package's Option functional
-    options as the variadic argument for modifying how the request will be
-    made, or extracting information from the raw HTTP response.
-
-  * ListObjectsPagesWithContext - same as ListObjectsPages, but adds support for
-    the Context pattern. Similar to ListObjectsWithContext this method also
-    takes the request package's Option function option types as the variadic
-    argument.
-
-In addition to the API operations the SDK also includes several higher level
-methods that abstract checking for and waiting for an AWS resource to be in
-a desired state. In this list we'll use WaitUntilBucketExists to demonstrate
-the different forms of waiters.
-
-  * WaitUntilBucketExists. - Method to make API request to query an AWS service for
-    a resource's state. Will return successfully when that state is accomplished.
-
-  * WaitUntilBucketExistsWithContext - Same as WaitUntilBucketExists, but adds
-    support for the Context pattern. In addition these methods take request
-    package's WaiterOptions to configure the waiter, and how underlying request
-    will be made by the SDK.
-
-The API method will document which error codes the service might return for
-the operation. These errors will also be available as const strings prefixed
-with "ErrCode" in the service client's package. If there are no errors listed
-in the API's SDK documentation you'll need to consult the AWS service's API
-documentation for the errors that could be returned.
-
-```go
-  ctx := context.Background()
-
-  result, err := svc.GetObjectWithContext(ctx, &s3.GetObjectInput{
-      Bucket: aws.String("my-bucket"),
-      Key: aws.String("my-key"),
-  })
-  if err != nil {
-      // Cast err to awserr.Error to handle specific error codes.
-      aerr, ok := err.(awserr.Error)
-      if ok && aerr.Code() == s3.ErrCodeNoSuchKey {
-          // Specific error code handling
-      }
-      return err
-  }
-
-  // Make sure to close the body when done with it for S3 GetObject APIs or
-  // will leak connections.
-  defer result.Body.Close()
-
-  fmt.Println("Object Size:", aws.Int64Value(result.ContentLength))
-```
-
-### API Request Pagination and Resource Waiters
-
-Pagination helper methods are suffixed with "Pages", and provide the
-functionality needed to round trip API page requests. Pagination methods
-take a callback function that will be called for each page of the API's response.
-
-```go
-   objects := []string{}
-   err := svc.ListObjectsPagesWithContext(ctx, &s3.ListObjectsInput{
-       Bucket: aws.String(myBucket),
-   }, func(p *s3.ListObjectsOutput, lastPage bool) bool {
-       for _, o := range p.Contents {
-           objects = append(objects, aws.StringValue(o.Key))
-       }
-       return true // continue paging
-   })
-   if err != nil {
-       panic(fmt.Sprintf("failed to list objects for bucket, %s, %v", myBucket, err))
-   }
-
-   fmt.Println("Objects in bucket:", objects)
-```
-
-Waiter helper methods provide the functionality to wait for an AWS resource
-state. These methods abstract the logic needed to check the state of an
-AWS resource, and wait until that resource is in a desired state. The waiter
-will block until the resource is in the state that is desired, an error occurs,
-or the waiter times out. If a resource times out the error code returned will
-be request.WaiterResourceNotReadyErrorCode.
-
-```go
-  err := svc.WaitUntilBucketExistsWithContext(ctx, &s3.HeadBucketInput{
-      Bucket: aws.String(myBucket),
-  })
-  if err != nil {
-      aerr, ok := err.(awserr.Error)
-      if ok && aerr.Code() == request.WaiterResourceNotReadyErrorCode {
-          fmt.Fprintf(os.Stderr, "timed out while waiting for bucket to exist")
-      }
-      panic(fmt.Errorf("failed to wait for bucket to exist, %v", err))
-  }
-  fmt.Println("Bucket", myBucket, "exists")
-```
-
-## Complete SDK Example
-
-This example shows a complete working Go file which will upload a file to S3
-and use the Context pattern to implement timeout logic that will cancel the
-request if it takes too long. This example highlights how to use sessions,
-create a service client, make a request, handle the error, and process the
-response.
-
-```go
-  package main
-
-  import (
-  	"context"
-  	"flag"
-  	"fmt"
-  	"os"
-  	"time"
-
-  	"github.com/aws/aws-sdk-go/aws"
-  	"github.com/aws/aws-sdk-go/aws/awserr"
-  	"github.com/aws/aws-sdk-go/aws/request"
-  	"github.com/aws/aws-sdk-go/aws/session"
-  	"github.com/aws/aws-sdk-go/service/s3"
-  )
-
-  // Uploads a file to S3 given a bucket and object key. Also takes a duration
-  // value to terminate the update if it doesn't complete within that time.
-  //
-  // The AWS Region needs to be provided in the AWS shared config or on the
-  // environment variable as `AWS_REGION`. Credentials also must be provided
-  // Will default to shared config file, but can load from environment if provided.
-  //
-  // Usage:
-  //   # Upload myfile.txt to myBucket/myKey. Must complete within 10 minutes or will fail
-  //   go run withContext.go -b mybucket -k myKey -d 10m < myfile.txt
-  func main() {
-  	var bucket, key string
-  	var timeout time.Duration
-
-  	flag.StringVar(&bucket, "b", "", "Bucket name.")
-  	flag.StringVar(&key, "k", "", "Object key name.")
-  	flag.DurationVar(&timeout, "d", 0, "Upload timeout.")
-  	flag.Parse()
-
-  	// All clients require a Session. The Session provides the client with
- 	// shared configuration such as region, endpoint, and credentials. A
- 	// Session should be shared where possible to take advantage of
- 	// configuration and credential caching. See the session package for
- 	// more information.
-  	sess := session.Must(session.NewSession())
-
- 	// Create a new instance of the service's client with a Session.
- 	// Optional aws.Config values can also be provided as variadic arguments
- 	// to the New function. This option allows you to provide service
- 	// specific configuration.
-  	svc := s3.New(sess)
-
-  	// Create a context with a timeout that will abort the upload if it takes
-  	// more than the passed in timeout.
-  	ctx := context.Background()
-  	var cancelFn func()
-  	if timeout > 0 {
-  		ctx, cancelFn = context.WithTimeout(ctx, timeout)
-  	}
-  	// Ensure the context is canceled to prevent leaking.
-  	// See context package for more information, https://golang.org/pkg/context/
-  	defer cancelFn()
-
-  	// Uploads the object to S3. The Context will interrupt the request if the
-  	// timeout expires.
-  	_, err := svc.PutObjectWithContext(ctx, &s3.PutObjectInput{
-  		Bucket: aws.String(bucket),
-  		Key:    aws.String(key),
-  		Body:   os.Stdin,
-  	})
-  	if err != nil {
-  		if aerr, ok := err.(awserr.Error); ok && aerr.Code() == request.CanceledErrorCode {
-  			// If the SDK can determine the request or retry delay was canceled
-  			// by a context the CanceledErrorCode error code will be returned.
-  			fmt.Fprintf(os.Stderr, "upload canceled due to timeout, %v\n", err)
-  		} else {
-  			fmt.Fprintf(os.Stderr, "failed to upload object, %v\n", err)
-  		}
-  		os.Exit(1)
-  	}
-
-  	fmt.Printf("successfully uploaded file to %s/%s\n", bucket, key)
-  }

+## Migration Guide from v2 -> v3
+
+Version 3 adds several new, frequently requested features.  To do so, it introduces a few breaking changes.  We've worked to keep these as minimal as possible.  This guide explains the breaking changes and how you can quickly update your code.
+
+### `Token.Claims` is now an interface type
+
+The most requested feature from the 2.0 verison of this library was the ability to provide a custom type to the JSON parser for claims. This was implemented by introducing a new interface, `Claims`, to replace `map[string]interface{}`.  We also included two concrete implementations of `Claims`: `MapClaims` and `StandardClaims`.
+
+`MapClaims` is an alias for `map[string]interface{}` with built in validation behavior.  It is the default claims type when using `Parse`.  The usage is unchanged except you must type cast the claims property.
+
+The old example for parsing a token looked like this..
+
+```go
+	if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
+		fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
+	}
+```
+
+is now directly mapped to...
+
+```go
+	if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
+		claims := token.Claims.(jwt.MapClaims)
+		fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
+	}
+```
+
+`StandardClaims` is designed to be embedded in your custom type.  You can supply a custom claims type with the new `ParseWithClaims` function.  Here's an example of using a custom claims type.
+
+```go
+	type MyCustomClaims struct {
+		User string
+		*StandardClaims
+	}
+	
+	if token, err := jwt.ParseWithClaims(tokenString, &MyCustomClaims{}, keyLookupFunc); err == nil {
+		claims := token.Claims.(*MyCustomClaims)
+		fmt.Printf("Token for user %v expires %v", claims.User, claims.StandardClaims.ExpiresAt)
+	}
+```
+
+### `ParseFromRequest` has been moved
+
+To keep this library focused on the tokens without becoming overburdened with complex request processing logic, `ParseFromRequest` and its new companion `ParseFromRequestWithClaims` have been moved to a subpackage, `request`.  The method signatues have also been augmented to receive a new argument: `Extractor`.
+
+`Extractors` do the work of picking the token string out of a request.  The interface is simple and composable.
+
+This simple parsing example:
+
+```go
+	if token, err := jwt.ParseFromRequest(tokenString, req, keyLookupFunc); err == nil {
+		fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
+	}
+```
+
+is directly mapped to:
+
+```go
+	if token, err := request.ParseFromRequest(req, request.OAuth2Extractor, keyLookupFunc); err == nil {
+		claims := token.Claims.(jwt.MapClaims)
+		fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
+	}
+```
+
+There are several concrete `Extractor` types provided for your convenience:
+
+* `HeaderExtractor` will search a list of headers until one contains content.
+* `ArgumentExtractor` will search a list of keys in request query and form arguments until one contains content.
+* `MultiExtractor` will try a list of `Extractors` in order until one returns content.
+* `AuthorizationHeaderExtractor` will look in the `Authorization` header for a `Bearer` token.
+* `OAuth2Extractor` searches the places an OAuth2 token would be specified (per the spec): `Authorization` header and `access_token` argument
+* `PostExtractionFilter` wraps an `Extractor`, allowing you to process the content before it's parsed.  A simple example is stripping the `Bearer ` text from a header
+
+
+### RSA signing methods no longer accept `[]byte` keys
+
+Due to a [critical vulnerability](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/), we've decided the convenience of accepting `[]byte` instead of `rsa.PublicKey` or `rsa.PrivateKey` isn't worth the risk of misuse.
+
+To replace this behavior, we've added two helper methods: `ParseRSAPrivateKeyFromPEM(key []byte) (*rsa.PrivateKey, error)` and `ParseRSAPublicKeyFromPEM(key []byte) (*rsa.PublicKey, error)`.  These are just simple helpers for unpacking PEM encoded PKCS1 and PKCS8 keys. If your keys are encoded any other way, all you need to do is convert them to the `crypto/rsa` package's types.
+
+```go 
+	func keyLookupFunc(*Token) (interface{}, error) {
+		// Don't forget to validate the alg is what you expect:
+		if _, ok := token.Method.(*jwt.SigningMethodRSA); !ok {
+			return nil, fmt.Errorf("Unexpected signing method: %v", token.Header["alg"])
+		}
+		
+		// Look up key 
+		key, err := lookupPublicKey(token.Header["kid"])
+		if err != nil {
+			return nil, err
+		}
+		
+		// Unpack key from PEM encoded PKCS8
+		return jwt.ParseRSAPublicKeyFromPEM(key)
+	}
+```

+## `jwt-go` Version History
+
+#### 3.0.0
+
+* **Compatibility Breaking Changes**: See MIGRATION_GUIDE.md for tips on updating your code
+	* Dropped support for `[]byte` keys when using RSA signing methods.  This convenience feature could contribute to security vulnerabilities involving mismatched key types with signing methods.
+	* `ParseFromRequest` has been moved to `request` subpackage and usage has changed
+	* The `Claims` property on `Token` is now type `Claims` instead of `map[string]interface{}`.  The default value is type `MapClaims`, which is an alias to `map[string]interface{}`.  This makes it possible to use a custom type when decoding claims.
+* Other Additions and Changes
+	* Added `Claims` interface type to allow users to decode the claims into a custom type
+	* Added `ParseWithClaims`, which takes a third argument of type `Claims`.  Use this function instead of `Parse` if you have a custom type you'd like to decode into.
+	* Dramatically improved the functionality and flexibility of `ParseFromRequest`, which is now in the `request` subpackage
+	* Added `ParseFromRequestWithClaims` which is the `FromRequest` equivalent of `ParseWithClaims`
+	* Added new interface type `Extractor`, which is used for extracting JWT strings from http requests.  Used with `ParseFromRequest` and `ParseFromRequestWithClaims`.
+	* Added several new, more specific, validation errors to error type bitmask
+	* Moved examples from README to executable example files
+	* Signing method registry is now thread safe
+	* Added new property to `ValidationError`, which contains the raw error returned by calls made by parse/verify (such as those returned by keyfunc or json parser)
+
+#### 2.7.0
+
+This will likely be the last backwards compatible release before 3.0.0, excluding essential bug fixes.
+
+* Added new option `-show` to the `jwt` command that will just output the decoded token without verifying
+* Error text for expired tokens includes how long it's been expired
+* Fixed incorrect error returned from `ParseRSAPublicKeyFromPEM`
+* Documentation updates
+
+#### 2.6.0
+
+* Exposed inner error within ValidationError
+* Fixed validation errors when using UseJSONNumber flag
+* Added several unit tests
+
+#### 2.5.0
+
+* Added support for signing method none.  You shouldn't use this.  The API tries to make this clear.
+* Updated/fixed some documentation
+* Added more helpful error message when trying to parse tokens that begin with `BEARER `
+
+#### 2.4.0
+
+* Added new type, Parser, to allow for configuration of various parsing parameters
+	* You can now specify a list of valid signing methods.  Anything outside this set will be rejected.
+	* You can now opt to use the `json.Number` type instead of `float64` when parsing token JSON
+* Added support for [Travis CI](https://travis-ci.org/dgrijalva/jwt-go)
+* Fixed some bugs with ECDSA parsing
+
+#### 2.3.0
+
+* Added support for ECDSA signing methods
+* Added support for RSA PSS signing methods (requires go v1.4)
+
+#### 2.2.0
+
+* Gracefully handle a `nil` `Keyfunc` being passed to `Parse`.  Result will now be the parsed token and an error, instead of a panic.
+
+#### 2.1.0
+
+Backwards compatible API change that was missed in 2.0.0.
+
+* The `SignedString` method on `Token` now takes `interface{}` instead of `[]byte`
+
+#### 2.0.0
+
+There were two major reasons for breaking backwards compatibility with this update.  The first was a refactor required to expand the width of the RSA and HMAC-SHA signing implementations.  There will likely be no required code changes to support this change.
+
+The second update, while unfortunately requiring a small change in integration, is required to open up this library to other signing methods.  Not all keys used for all signing methods have a single standard on-disk representation.  Requiring `[]byte` as the type for all keys proved too limiting.  Additionally, this implementation allows for pre-parsed tokens to be reused, which might matter in an application that parses a high volume of tokens with a small set of keys.  Backwards compatibilty has been maintained for passing `[]byte` to the RSA signing methods, but they will also accept `*rsa.PublicKey` and `*rsa.PrivateKey`.
+
+It is likely the only integration change required here will be to change `func(t *jwt.Token) ([]byte, error)` to `func(t *jwt.Token) (interface{}, error)` when calling `Parse`.
+
+* **Compatibility Breaking Changes**
+	* `SigningMethodHS256` is now `*SigningMethodHMAC` instead of `type struct`
+	* `SigningMethodRS256` is now `*SigningMethodRSA` instead of `type struct`
+	* `KeyFunc` now returns `interface{}` instead of `[]byte`
+	* `SigningMethod.Sign` now takes `interface{}` instead of `[]byte` for the key
+	* `SigningMethod.Verify` now takes `interface{}` instead of `[]byte` for the key
+* Renamed type `SigningMethodHS256` to `SigningMethodHMAC`.  Specific sizes are now just instances of this type.
+    * Added public package global `SigningMethodHS256`
+    * Added public package global `SigningMethodHS384`
+    * Added public package global `SigningMethodHS512`
+* Renamed type `SigningMethodRS256` to `SigningMethodRSA`.  Specific sizes are now just instances of this type.
+    * Added public package global `SigningMethodRS256`
+    * Added public package global `SigningMethodRS384`
+    * Added public package global `SigningMethodRS512`
+* Moved sample private key for HMAC tests from an inline value to a file on disk.  Value is unchanged.
+* Refactored the RSA implementation to be easier to read
+* Exposed helper methods `ParseRSAPrivateKeyFromPEM` and `ParseRSAPublicKeyFromPEM`
+
+#### 1.0.2
+
+* Fixed bug in parsing public keys from certificates
+* Added more tests around the parsing of keys for RS256
+* Code refactoring in RS256 implementation.  No functional changes
+
+#### 1.0.1
+
+* Fixed panic if RS256 signing method was passed an invalid key
+
+#### 1.0.0
+
+* First versioned release
+* API stabilized
+* Supports creating, signing, parsing, and validating JWT tokens
+* Supports RS256 and HS256 signing methods

 在获取所有键值的过程中，特殊语法 `%(<name>)s` 会被应用，其中 `<name>` 可以是相同分区或者默认分区下的键名。字符串 `%(<name>)s` 会被相应的键值所替代，如果指定的键不存在，则会用空字符串替代。您可以最多使用 99 层的递归嵌套。

-#### 读取自增键名
+### 无法解析的分区

+如果遇到一些比较特殊的分区，它们不包含常见的键值对，而是没有固定格式的纯文本，则可以使用 `LoadOptions.UnparsableSections` 进行处理：

+```go

+
+/* --- start ---

+------  end  --- */
+```
+
+### 读取自增键名
 
 如果数据源中的键名为 `-`，则认为该键使用了自增键名的特殊语法。计数器从 1 开始，并且分区之间是相互独立的。

-# Go support for Protocol Buffers
-
-Google's data interchange format.
-Copyright 2010 The Go Authors.
-https://github.com/golang/protobuf
-
-This package and the code it generates requires at least Go 1.4.
-
-This software implements Go bindings for protocol buffers.  For
-information about protocol buffers themselves, see
-	https://developers.google.com/protocol-buffers/
-
-## Installation ##
-
-To use this software, you must:
-- Install the standard C++ implementation of protocol buffers from
-	https://developers.google.com/protocol-buffers/
-- Of course, install the Go compiler and tools from
-	https://golang.org/
-  See
-	https://golang.org/doc/install
-  for details or, if you are using gccgo, follow the instructions at
-	https://golang.org/doc/install/gccgo
-- Grab the code from the repository and install the proto package.
-  The simplest way is to run `go get -u github.com/golang/protobuf/{proto,protoc-gen-go}`.
-  The compiler plugin, protoc-gen-go, will be installed in $GOBIN,
-  defaulting to $GOPATH/bin.  It must be in your $PATH for the protocol
-  compiler, protoc, to find it.
-
-This software has two parts: a 'protocol compiler plugin' that
-generates Go source files that, once compiled, can access and manage
-protocol buffers; and a library that implements run-time support for
-encoding (marshaling), decoding (unmarshaling), and accessing protocol
-buffers.
-
-There is support for gRPC in Go using protocol buffers.
-See the note at the bottom of this file for details.
-
-There are no insertion points in the plugin.
-
-
-## Using protocol buffers with Go ##
-
-Once the software is installed, there are two steps to using it.
-First you must compile the protocol buffer definitions and then import
-them, with the support library, into your program.
-
-To compile the protocol buffer definition, run protoc with the --go_out
-parameter set to the directory you want to output the Go code to.
-
-	protoc --go_out=. *.proto
-
-The generated files will be suffixed .pb.go.  See the Test code below
-for an example using such a file.
-
-
-The package comment for the proto library contains text describing
-the interface provided in Go for protocol buffers. Here is an edited
-version.
-
-==========
-
-The proto package converts data structures to and from the
-wire format of protocol buffers.  It works in concert with the
-Go source code generated for .proto files by the protocol compiler.
-
-A summary of the properties of the protocol buffer interface
-for a protocol buffer variable v:
-
-  - Names are turned from camel_case to CamelCase for export.
-  - There are no methods on v to set fields; just treat
-  	them as structure fields.
-  - There are getters that return a field's value if set,
-	and return the field's default value if unset.
-	The getters work even if the receiver is a nil message.
-  - The zero value for a struct is its correct initialization state.
-	All desired fields must be set before marshaling.
-  - A Reset() method will restore a protobuf struct to its zero state.
-  - Non-repeated fields are pointers to the values; nil means unset.
-	That is, optional or required field int32 f becomes F *int32.
-  - Repeated fields are slices.
-  - Helper functions are available to aid the setting of fields.
-	Helpers for getting values are superseded by the
-	GetFoo methods and their use is deprecated.
-		msg.Foo = proto.String("hello") // set field
-  - Constants are defined to hold the default values of all fields that
-	have them.  They have the form Default_StructName_FieldName.
-	Because the getter methods handle defaulted values,
-	direct use of these constants should be rare.
-  - Enums are given type names and maps from names to values.
-	Enum values are prefixed with the enum's type name. Enum types have
-	a String method, and a Enum method to assist in message construction.
-  - Nested groups and enums have type names prefixed with the name of
-  	the surrounding message type.
-  - Extensions are given descriptor names that start with E_,
-	followed by an underscore-delimited list of the nested messages
-	that contain it (if any) followed by the CamelCased name of the
-	extension field itself.  HasExtension, ClearExtension, GetExtension
-	and SetExtension are functions for manipulating extensions.
-  - Oneof field sets are given a single field in their message,
-	with distinguished wrapper types for each possible field value.
-  - Marshal and Unmarshal are functions to encode and decode the wire format.
-
-When the .proto file specifies `syntax="proto3"`, there are some differences:
-
-  - Non-repeated fields of non-message type are values instead of pointers.
-  - Getters are only generated for message and oneof fields.
-  - Enum types do not get an Enum method.
-
-Consider file test.proto, containing
-
-```proto
-	package example;
-	
-	enum FOO { X = 17; };
-	
-	message Test {
-	  required string label = 1;
-	  optional int32 type = 2 [default=77];
-	  repeated int64 reps = 3;
-	  optional group OptionalGroup = 4 {
-	    required string RequiredField = 5;
-	  }
-	}
-```
-
-To create and play with a Test object from the example package,
-
-```go
-	package main
-
-	import (
-		"log"
-
-		"github.com/golang/protobuf/proto"
-		"path/to/example"
-	)
-
-	func main() {
-		test := &example.Test {
-			Label: proto.String("hello"),
-			Type:  proto.Int32(17),
-			Reps:  []int64{1, 2, 3},
-			Optionalgroup: &example.Test_OptionalGroup {
-				RequiredField: proto.String("good bye"),
-			},
-		}
-		data, err := proto.Marshal(test)
-		if err != nil {
-			log.Fatal("marshaling error: ", err)
-		}
-		newTest := &example.Test{}
-		err = proto.Unmarshal(data, newTest)
-		if err != nil {
-			log.Fatal("unmarshaling error: ", err)
-		}
-		// Now test and newTest contain the same data.
-		if test.GetLabel() != newTest.GetLabel() {
-			log.Fatalf("data mismatch %q != %q", test.GetLabel(), newTest.GetLabel())
-		}
-		// etc.
-	}
-```
-
-## Parameters ##
-
-To pass extra parameters to the plugin, use a comma-separated
-parameter list separated from the output directory by a colon:
-
-
-	protoc --go_out=plugins=grpc,import_path=mypackage:. *.proto
-
-
-- `import_prefix=xxx` - a prefix that is added onto the beginning of
-  all imports. Useful for things like generating protos in a
-  subdirectory, or regenerating vendored protobufs in-place.
-- `import_path=foo/bar` - used as the package if no input files
-  declare `go_package`. If it contains slashes, everything up to the
-  rightmost slash is ignored.
-- `plugins=plugin1+plugin2` - specifies the list of sub-plugins to
-  load. The only plugin in this repo is `grpc`.
-- `Mfoo/bar.proto=quux/shme` - declares that foo/bar.proto is
-  associated with Go package quux/shme.  This is subject to the
-  import_prefix parameter.
-
-## gRPC Support ##
-
-If a proto file specifies RPC services, protoc-gen-go can be instructed to
-generate code compatible with gRPC (http://www.grpc.io/). To do this, pass
-the `plugins` parameter to protoc-gen-go; the usual way is to insert it into
-the --go_out argument to protoc:
-
-	protoc --go_out=plugins=grpc:. *.proto
-
-## Plugins ##
-
-The `protoc-gen-go/generator` package exposes a plugin interface,
-which is used by the gRPC code generation. This interface is not
-supported and is subject to incompatible changes without notice.

+Package context stores values shared during a request lifetime.
+
+Note: gorilla/context, having been born well before `context.Context` existed,
+does not play well > with the shallow copying of the request that
+[`http.Request.WithContext`](https://golang.org/pkg/net/http/#Request.WithContext)
+(added to net/http Go 1.7 onwards) performs. You should either use *just*
+gorilla/context, or moving forward, the new `http.Request.Context()`.
+
+For example, a router can set variables extracted from the URL and later
+application handlers can access those values, or it can be used to store
+sessions values to be saved at the end of a request. There are several
+others common uses.
+
+The idea was posted by Brad Fitzpatrick to the go-nuts mailing list:
+
+	http://groups.google.com/group/golang-nuts/msg/e2d679d303aa5d53
+
+Here's the basic usage: first define the keys that you will need. The key
+type is interface{} so a key can be of any type that supports equality.
+Here we define a key using a custom int type to avoid name collisions:
+
+	package foo
+
+	import (
+		"github.com/gorilla/context"
+	)
+
+	type key int
+
+	const MyKey key = 0
+
+Then set a variable. Variables are bound to an http.Request object, so you
+need a request instance to set a value:
+
+	context.Set(r, MyKey, "bar")
+
+The application can later access the variable using the same key you provided:
+
+	func MyHandler(w http.ResponseWriter, r *http.Request) {
+		// val is "bar".
+		val := context.Get(r, foo.MyKey)
+
+		// returns ("bar", true)
+		val, ok := context.GetOk(r, foo.MyKey)
+		// ...
+	}
+
+And that's all about the basic usage. We discuss some other ideas below.
+
+Any type can be stored in the context. To enforce a given type, make the key
+private and wrap Get() and Set() to accept and return values of a specific
+type:
+
+	type key int
+
+	const mykey key = 0
+
+	// GetMyKey returns a value for this package from the request values.
+	func GetMyKey(r *http.Request) SomeType {
+		if rv := context.Get(r, mykey); rv != nil {
+			return rv.(SomeType)
+		}
+		return nil
+	}
+
+	// SetMyKey sets a value for this package in the request values.
+	func SetMyKey(r *http.Request, val SomeType) {
+		context.Set(r, mykey, val)
+	}
+
+Variables must be cleared at the end of a request, to remove all values
+that were stored. This can be done in an http.Handler, after a request was
+served. Just call Clear() passing the request:
+
+	context.Clear(r)
+
+...or use ClearHandler(), which conveniently wraps an http.Handler to clear
+variables at the end of a request lifetime.
+
+The Routers from the packages gorilla/mux and gorilla/pat call Clear()
+so if you are using either of them you don't need to clear the context manually.

+Notes on Go Swift
+=================
+
+Make a builder style interface like the Google Go APIs?  Advantages
+are that it is easy to add named methods to the service object to do
+specific things.  Slightly less efficient.  Not sure about how to
+return extra stuff though - in an object?
+
+Make a container struct so these could be methods on it?
+
+Make noResponse check for 204?
+
+Make storage public so it can be extended easily?
+
+Rename to go-swift to match user agent string?
+
+Reconnect on auth error - 401 when token expires isn't tested
+
+Make more api compatible with python cloudfiles?
+
+Retry operations on timeout / network errors?
+- also 408 error
+- GET requests only?
+
+Make Connection thread safe - whenever it is changed take a write lock whenever it is read from a read lock
+
+Add extra headers field to Connection (for via etc)
+
+Make errors use an error heirachy then can catch them with a type assertion
+
+ Error(...)
+ ObjectCorrupted{ Error }
+
+Make a Debug flag in connection for logging stuff
+
+Object If-Match, If-None-Match, If-Modified-Since, If-Unmodified-Since etc
+
+Object range
+
+Object create, update with X-Delete-At or X-Delete-After
+
+Large object support
+- check uploads are less than 5GB in normal mode?
+
+Access control CORS?
+
+Swift client retries and backs off for all types of errors
+
+Implement net error interface?
+
+type Error interface {
+    error
+    Timeout() bool   // Is the error a timeout?
+    Temporary() bool // Is the error temporary?
+}

+# Contributing to Docker open source projects
+
+Want to hack on this project? Awesome! Here are instructions to get you started.
+
+This project is a part of the [Docker](https://www.docker.com) project, and follows
+the same rules and principles. If you're already familiar with the way
+Docker does things, you'll feel right at home.
+
+Otherwise, go read Docker's
+[contributions guidelines](https://github.com/docker/docker/blob/master/CONTRIBUTING.md),
+[issue triaging](https://github.com/docker/docker/blob/master/project/ISSUE-TRIAGE.md),
+[review process](https://github.com/docker/docker/blob/master/project/REVIEWING.md) and
+[branches and tags](https://github.com/docker/docker/blob/master/project/BRANCHES-AND-TAGS.md).
+
+For an in-depth description of our contribution process, visit the
+contributors guide: [Understand how to contribute](https://docs.docker.com/opensource/workflow/make-a-contribution/)
+
+### Sign your work
+
+The sign-off is a simple line at the end of the explanation for the patch. Your
+signature certifies that you wrote the patch or otherwise have the right to pass
+it on as an open-source patch. The rules are pretty simple: if you can certify
+the below (from [developercertificate.org](http://developercertificate.org/)):
+
+```
+Developer Certificate of Origin
+Version 1.1
+
+Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
+1 Letterman Drive
+Suite D4700
+San Francisco, CA, 94129
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+
+Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the best
+    of my knowledge, is covered under an appropriate open source
+    license and I have the right under that license to submit that
+    work with modifications, whether created in whole or in part
+    by me, under the same open source license (unless I am
+    permitted to submit under a different license), as indicated
+    in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
+
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including all
+    personal information I submit with it, including my sign-off) is
+    maintained indefinitely and may be redistributed consistent with
+    this project or the open source license(s) involved.
+```
+
+Then you just add a line to every git commit message:
+
+    Signed-off-by: Joe Smith <joe.smith@email.com>
+
+Use your real name (sorry, no pseudonyms or anonymous contributions.)
+
+If you set your `user.name` and `user.email` git configs, you can sign your
+commit automatically with `git commit -s`.

-# OCI Image Format Specification
-<div>
-<a href="https://travis-ci.org/opencontainers/image-spec">
-<img src="https://travis-ci.org/opencontainers/image-spec.svg?branch=master"></img>
-</a>
-</div>
-
-The OCI Image Format project creates and maintains the software shipping container image format spec (OCI Image Format).
-
-**[The specification can be found here](spec.md).**
-
-This repository also provides [Go types](specs-go), [intra-blob validation tooling, and JSON Schema](schema).
-The Go types and validation should be compatible with the current Go release; earlier Go releases are not supported.
-
-Additional documentation about how this group operates:
-
-- [Code of Conduct](https://github.com/opencontainers/tob/blob/d2f9d68c1332870e40693fe077d311e0742bc73d/code-of-conduct.md)
-- [Roadmap](#roadmap)
-- [Releases](RELEASES.md)
-- [Project Documentation](project.md)
-
-The _optional_ and _base_ layers of all OCI projects are tracked in the [OCI Scope Table](https://www.opencontainers.org/about/oci-scope-table).
-
-## Running an OCI Image
-
-The OCI Image Format partner project is the [OCI Runtime Spec project](https://github.com/opencontainers/runtime-spec).
-The Runtime Specification outlines how to run a "[filesystem bundle](https://github.com/opencontainers/runtime-spec/blob/master/bundle.md)" that is unpacked on disk.
-At a high-level an OCI implementation would download an OCI Image then unpack that image into an OCI Runtime filesystem bundle.
-At this point the OCI Runtime Bundle would be run by an OCI Runtime.
-
-This entire workflow supports the UX that users have come to expect from container engines like Docker and rkt: primarily, the ability to run an image with no additional arguments:
-
-* docker run example.com/org/app:v1.0.0
-* rkt run example.com/org/app,version=v1.0.0
-
-To support this UX the OCI Image Format contains sufficient information to launch the application on the target platform (e.g. command, arguments, environment variables, etc).
-
-## FAQ
-
-**Q: Why doesn't this project mention distribution?**
-
-A: Distribution, for example using HTTP as both Docker v2.2 and AppC do today, is currently out of scope on the [OCI Scope Table](https://www.opencontainers.org/about/oci-scope-table).
-There has been [some discussion on the TOB mailing list](https://groups.google.com/a/opencontainers.org/d/msg/tob/A3JnmI-D-6Y/tLuptPDHAgAJ) to make distribution an optional layer, but this topic is a work in progress.
-
-**Q: What happens to AppC or Docker Image Formats?**
-
-A: Existing formats can continue to be a proving ground for technologies, as needed.
-The OCI Image Format project strives to provide a dependable open specification that can be shared between different tools and be evolved for years or decades of compatibility; as the deb and rpm format have.
-
-Find more [FAQ on the OCI site](https://www.opencontainers.org/faq).
-
-## Roadmap
-
-The [GitHub milestones](https://github.com/opencontainers/image-spec/milestones) lay out the path to the OCI v1.0.0 release in late 2016.
-
-# Contributing
-
-Development happens on GitHub for the spec.
-Issues are used for bugs and actionable items and longer discussions can happen on the [mailing list](#mailing-list).
-
-The specification and code is licensed under the Apache 2.0 license found in the `LICENSE` file of this repository.
-
-## Discuss your design
-
-The project welcomes submissions, but please let everyone know what you are working on.
-
-Before undertaking a nontrivial change to this specification, send mail to the [mailing list](#mailing-list) to discuss what you plan to do.
-This gives everyone a chance to validate the design, helps prevent duplication of effort, and ensures that the idea fits.
-It also guarantees that the design is sound before code is written; a GitHub pull-request is not the place for high-level discussions.
-
-Typos and grammatical errors can go straight to a pull-request.
-When in doubt, start on the [mailing-list](#mailing-list).
-
-## Weekly Call
-
-The contributors and maintainers of all OCI projects have a weekly meeting Wednesdays at 2:00 PM (USA Pacific).
-Everyone is welcome to participate via [UberConference web][UberConference] or audio-only: +1-415-968-0849 (no PIN needed).
-An initial agenda will be posted to the [mailing list](#mailing-list) earlier in the week, and everyone is welcome to propose additional topics or suggest other agenda alterations there.
-Minutes are posted to the [mailing list](#mailing-list) and minutes from past calls are archived [here][minutes].
-
-## Mailing List
-
-You can subscribe and join the mailing list on [Google Groups](https://groups.google.com/a/opencontainers.org/forum/#!forum/dev).
-
-## IRC
-
-OCI discussion happens on #opencontainers on Freenode ([logs][irc-logs]).
-
-## Markdown style
-
-To keep consistency throughout the Markdown files in the Open Container spec all files should be formatted one sentence per line.
-This fixes two things: it makes diffing easier with git and it resolves fights about line wrapping length.
-For example, this paragraph will span three lines in the Markdown source.
-
-## Git commit
-
-### Sign your work
-
-The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch.
-The rules are pretty simple: if you can certify the below (from [developercertificate.org](http://developercertificate.org/)):

-2. Limit the subject line to 50 characters
-3. Capitalize the subject line
-4. Do not end the subject line with a period
-5. Use the imperative mood in the subject line
-6. Wrap the body at 72 characters
-7. Use the body to explain what and why vs. how
-  * If there was important/useful/essential conversation or information, copy or include a reference
-8. When possible, one keyword to scope the change in the subject (i.e. "README: ...", "runtime: ...")

-# Prometheus Go client library
-
-[![Build Status](https://travis-ci.org/prometheus/client_golang.svg?branch=master)](https://travis-ci.org/prometheus/client_golang)
-[![Go Report Card](https://goreportcard.com/badge/github.com/prometheus/client_golang)](https://goreportcard.com/report/github.com/prometheus/client_golang)
-
-This is the [Go](http://golang.org) client library for
-[Prometheus](http://prometheus.io). It has two separate parts, one for
-instrumenting application code, and one for creating clients that talk to the
-Prometheus HTTP API.
-
-__This library requires Go1.7 or later.__
-
-## Important note about releases, versioning, tagging, stability, and your favorite Go dependency management tool
-
-While our goal is to follow [Semantic Versioning](https://semver.org/), this
-repository is still pre-1.0.0. To quote the
-[Semantic Versioning spec](https://semver.org/#spec-item-4): “Anything may
-change at any time. The public API should not be considered stable.” We know
-that this is at odds with the widespread use of this library. However, just
-declaring something 1.0.0 doesn't make it 1.0.0. Instead, we are working
-towards a 1.0.0 release that actually deserves its major version number.
-
-Having said that, we aim for always keeping the tip of master in a workable
-state and for only introducing ”mildly” breaking changes up to and including
-[v0.9.0](https://github.com/prometheus/client_golang/milestone/1). After that,
-a number of ”hard” breaking changes are planned, see the
-[v0.10.0 milestone](https://github.com/prometheus/client_golang/milestone/2),
-which should get the library much closer to 1.0.0 state.
-
-Dependency management in Go projects is still in flux, and there are many tools
-floating around. While [dep](https://golang.github.io/dep/) might develop into
-the de-facto standard tool, it is still officially experimental. The roadmap
-for this library has been laid out with a lot of sometimes painful experience
-in mind. We really cannot adjust it every other month to the needs of the
-currently most popular or most promising Go dependency management tool. The
-recommended course of action with dependency management tools is the following:
-
-- Do not expect strict post-1.0.0 semver semantics prior to the 1.0.0
-  release. If your dependency management tool expects strict post-1.0.0 semver
-  semantics, you have to wait. Sorry.
-- If you want absolute certainty, please lock to a specific commit. You can
-  also lock to tags, but please don't ask for more tagging. This would suggest
-  some release or stability testing procedure that simply is not in place. As
-  said above, we are aiming for stability of the tip of master, but if we
-  tagged every single commit, locking to tags would be the same as locking to
-  commits.
-- If you want to get the newer features and improvements and are willing to
-  take the minor risk of newly introduced bugs and “mild” breakage, just always
-  update to the tip of master (which is essentially the original idea of Go
-  dependency management). We recommend to not use features marked as
-  _deprecated_ in this case.
-- Once [v0.9.0](https://github.com/prometheus/client_golang/milestone/1) is
-  out, you could lock to v0.9.x to get bugfixes (and perhaps minor new
-  features) while avoiding the “hard” breakage that will come with post-0.9
-  features.

-## Instrumenting applications
-
-[![code-coverage](http://gocover.io/_badge/github.com/prometheus/client_golang/prometheus)](http://gocover.io/github.com/prometheus/client_golang/prometheus) [![go-doc](https://godoc.org/github.com/prometheus/client_golang/prometheus?status.svg)](https://godoc.org/github.com/prometheus/client_golang/prometheus)
-
-The
-[`prometheus` directory](https://github.com/prometheus/client_golang/tree/master/prometheus)
-contains the instrumentation library. See the
-[best practices section](http://prometheus.io/docs/practices/naming/) of the
-Prometheus documentation to learn more about instrumenting applications.
-
-The
-[`examples` directory](https://github.com/prometheus/client_golang/tree/master/examples)
-contains simple examples of instrumented code.
-
-## Client for the Prometheus HTTP API
-
-[![code-coverage](http://gocover.io/_badge/github.com/prometheus/client_golang/api/prometheus/v1)](http://gocover.io/github.com/prometheus/client_golang/api/prometheus/v1) [![go-doc](https://godoc.org/github.com/prometheus/client_golang/api/prometheus?status.svg)](https://godoc.org/github.com/prometheus/client_golang/api)
-
-The
-[`api/prometheus` directory](https://github.com/prometheus/client_golang/tree/master/api/prometheus)
-contains the client for the
-[Prometheus HTTP API](http://prometheus.io/docs/querying/api/). It allows you
-to write Go applications that query time series data from a Prometheus
-server. It is still in alpha stage.
-
-## Where is `model`, `extraction`, and `text`?
-
-The `model` packages has been moved to
-[`prometheus/common/model`](https://github.com/prometheus/common/tree/master/model).
-
-The `extraction` and `text` packages are now contained in
-[`prometheus/common/expfmt`](https://github.com/prometheus/common/tree/master/expfmt).

+# Generating Bash Completions For Your Own cobra.Command
+
+Generating bash completions from a cobra command is incredibly easy. An actual program which does so for the kubernetes kubectl binary is as follows:
+
+```go
+package main
+
+import (
+        "io/ioutil"
+        "os"
+
+        "github.com/GoogleCloudPlatform/kubernetes/pkg/kubectl/cmd"
+)
+
+func main() {
+        kubectl := cmd.NewFactory(nil).NewKubectlCommand(os.Stdin, ioutil.Discard, ioutil.Discard)
+        kubectl.GenBashCompletionFile("out.sh")
+}
+```
+
+That will get you completions of subcommands and flags. If you make additional annotations to your code, you can get even more intelligent and flexible behavior.
+
+## Creating your own custom functions
+
+Some more actual code that works in kubernetes:
+
+```bash
+const (
+        bash_completion_func = `__kubectl_parse_get()
+{
+    local kubectl_output out
+    if kubectl_output=$(kubectl get --no-headers "$1" 2>/dev/null); then
+        out=($(echo "${kubectl_output}" | awk '{print $1}'))
+        COMPREPLY=( $( compgen -W "${out[*]}" -- "$cur" ) )
+    fi
+}
+
+__kubectl_get_resource()
+{
+    if [[ ${#nouns[@]} -eq 0 ]]; then
+        return 1
+    fi
+    __kubectl_parse_get ${nouns[${#nouns[@]} -1]}
+    if [[ $? -eq 0 ]]; then
+        return 0
+    fi
+}
+
+__custom_func() {
+    case ${last_command} in
+        kubectl_get | kubectl_describe | kubectl_delete | kubectl_stop)
+            __kubectl_get_resource
+            return
+            ;;
+        *)
+            ;;
+    esac
+}
+`)
+```
+
+And then I set that in my command definition:
+
+```go
+cmds := &cobra.Command{
+	Use:   "kubectl",
+	Short: "kubectl controls the Kubernetes cluster manager",
+	Long: `kubectl controls the Kubernetes cluster manager.
+
+Find more information at https://github.com/GoogleCloudPlatform/kubernetes.`,
+	Run: runHelp,
+	BashCompletionFunction: bash_completion_func,
+}
+```
+
+The `BashCompletionFunction` option is really only valid/useful on the root command. Doing the above will cause `__custom_func()` to be called when the built in processor was unable to find a solution. In the case of kubernetes a valid command might look something like `kubectl get pod [mypod]`. If you type `kubectl get pod [tab][tab]` the `__customc_func()` will run because the cobra.Command only understood "kubectl" and "get." `__custom_func()` will see that the cobra.Command is "kubectl_get" and will thus call another helper `__kubectl_get_resource()`.  `__kubectl_get_resource` will look at the 'nouns' collected. In our example the only noun will be `pod`.  So it will call `__kubectl_parse_get pod`.  `__kubectl_parse_get` will actually call out to kubernetes and get any pods.  It will then set `COMPREPLY` to valid pods!
+
+## Have the completions code complete your 'nouns'
+
+In the above example "pod" was assumed to already be typed. But if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them. Simplified code from `kubectl get` looks like:
+
+```go
+validArgs []string = { "pods", "nodes", "services", "replicationControllers" }
+
+cmd := &cobra.Command{
+	Use:     "get [(-o|--output=)json|yaml|template|...] (RESOURCE [NAME] | RESOURCE/NAME ...)",
+	Short:   "Display one or many resources",
+	Long:    get_long,
+	Example: get_example,
+	Run: func(cmd *cobra.Command, args []string) {
+		err := RunGet(f, out, cmd, args)
+		util.CheckErr(err)
+	},
+	ValidArgs: validArgs,
+}
+```
+
+Notice we put the "ValidArgs" on the "get" subcommand. Doing so will give results like
+
+```bash
+# kubectl get [tab][tab]
+nodes                 pods                    replicationControllers  services
+```
+
+## Mark flags as required
+
+Most of the time completions will only show subcommands. But if a flag is required to make a subcommand work, you probably want it to show up when the user types [tab][tab].  Marking a flag as 'Required' is incredibly easy.
+
+```go
+cmd.MarkFlagRequired("pod")
+cmd.MarkFlagRequired("container")
+```
+
+and you'll get something like
+
+```bash
+# kubectl exec [tab][tab][tab]
+-c            --container=  -p            --pod=  
+```
+
+# Specify valid filename extensions for flags that take a filename
+
+In this example we use --filename= and expect to get a json or yaml file as the argument. To make this easier we annotate the --filename flag with valid filename extensions.
+
+```go
+	annotations := []string{"json", "yaml", "yml"}
+	annotation := make(map[string][]string)
+	annotation[cobra.BashCompFilenameExt] = annotations
+
+	flag := &pflag.Flag{
+		Name:        "filename",
+		Shorthand:   "f",
+		Usage:       usage,
+		Value:       value,
+		DefValue:    value.String(),
+		Annotations: annotation,
+	}
+	cmd.Flags().AddFlag(flag)
+```
+
+Now when you run a command with this filename flag you'll get something like
+
+```bash
+# kubectl create -f 
+test/                         example/                      rpmbuild/
+hello.yml                     test.json
+```
+
+So while there are many other files in the CWD it only shows me subdirs and those with valid extensions.

+# Generating Markdown Docs For Your Own cobra.Command
+
+## Generate markdown docs for the entire command tree
+
+This program can actually generate docs for the kubectl command in the kubernetes project
+
+```go
+package main
+
+import (
+	"io/ioutil"
+	"os"
+
+	"github.com/GoogleCloudPlatform/kubernetes/pkg/kubectl/cmd"
+	"github.com/spf13/cobra"
+)
+
+func main() {
+	kubectl := cmd.NewFactory(nil).NewKubectlCommand(os.Stdin, ioutil.Discard, ioutil.Discard)
+	cobra.GenMarkdownTree(kubectl, "./")
+}
+```
+
+This will generate a whole series of files, one for each command in the tree, in the directory specified (in this case "./")
+
+## Generate markdown docs for a single command
+
+You may wish to have more control over the output, or only generate for a single command, instead of the entire command tree. If this is the case you may prefer to `GenMarkdown` instead of `GenMarkdownTree`
+
+```go
+	out := new(bytes.Buffer)
+	cobra.GenMarkdown(cmd, out)
+```
+
+This will write the markdown doc for ONLY "cmd" into the out, buffer.
+
+## Customize the output
+
+Both `GenMarkdown` and `GenMarkdownTree` have alternate versions with callbacks to get some control of the output:
+
+```go
+func GenMarkdownTreeCustom(cmd *Command, dir string, filePrepender func(string) string, linkHandler func(string) string) {
+    //...
+}
+```
+
+```go
+func GenMarkdownCustom(cmd *Command, out *bytes.Buffer, linkHandler func(string) string) {
+    //...
+}
+```
+
+The `filePrepender` will prepend the return value given the full filepath to the rendered Markdown file. A common use case is to add front matter to use the generated documentation with [Hugo](http://gohugo.io/):
+
+```go
+const fmTemplate = `---
+date: %s
+title: "%s"
+slug: %s
+url: %s
+---
+`
+
+filePrepender := func(filename string) string {
+	now := time.Now().Format(time.RFC3339)
+	name := filepath.Base(filename)
+	base := strings.TrimSuffix(name, path.Ext(name))
+	url := "/commands/" + strings.ToLower(base) + "/"
+	return fmt.Sprintf(fmTemplate, now, strings.Replace(base, "_", " ", -1), base, url)
+}
+```
+
+The `linkHandler` can be used to customize the rendered internal links to the commands, given a filename:
+
+```go
+linkHandler := func(name string) string {
+	base := strings.TrimSuffix(name, path.Ext(name))
+	return "/commands/" + strings.ToLower(base) + "/"
+}
+```
