description: Explains how to use the OpenStack swift storage driver
|
||||
keywords: registry, service, driver, images, storage, swift
|
||||
title: OpenStack Swift storage driver
|
||||
---
|
||||
|
||||
An implementation of the `storagedriver.StorageDriver` interface that uses
|
||||
[OpenStack Swift](http://docs.openstack.org/developer/swift/) for object
|
||||
storage.
|
||||
|
||||
## Parameters
|
||||
|
||||
| Parameter | Required | Description |
|
||||
|:--------------|:---------|:--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
||||
| `authurl` | yes | URL for obtaining an auth token. https://storage.myprovider.com/v2.0 or https://storage.myprovider.com/v3/auth |
|
||||
| `username` | yes | Your Openstack user name. |
|
||||
| `password` | yes | Your Openstack password. |
|
||||
| `region` | no | The Openstack region in which your container exists. |
|
||||
| `container` | yes | The name of your Swift container where you wish to store the registry's data. The driver creates the named container during its initialization. |
|
||||
| `tenant` | no | Your Openstack tenant name. You can either use `tenant` or `tenantid`. |
|
||||
| `tenantid` | no | Your Openstack tenant name. You can either use `tenant` or `tenantid`. |
|
||||
| `domain` | no | Your Openstack domain name for Identity v3 API. You can either use `domain` or `domainid`. |
|
||||
| `domainid` | no | Your Openstack domain name for Identity v3 API. You can either use `domain` or `domainid`. |
|
||||
| `tenantdomain` | no | Your tenant's Openstack domain name for Identity v3 API. Only necessary if different from the <code>domain</code>. You can either use `tenantdomain` or `tenantdomainid`. |
|
||||
| `tenantdomainid` | no | Your tenant's Openstack domain id for Identity v3 API. Only necessary if different from the <code>domain</code>. You can either use `tenantdomain` or `tenantdomainid`. |
|
||||
| `trustid` | no | Your Openstack trust ID for Identity v3 API. |
|
||||
| `insecureskipverify` | no | Skips TLS verification if the value is wet to `true`. The default is `false`. |
|
||||
| `chunksize` | no | Size of the data segments for the Swift Dynamic Large Objects. This value should be a number (defaults to 5M). |
|
||||
| `prefix` | no | This is a prefix that is applied to all Swift keys to allow you to segment data in your container if necessary. Defaults to the empty string which is the container's root. |
|
||||
| `secretkey` | no | The secret key used to generate temporary URLs. |
|
||||
| `accesskey` | no | The access key to generate temporary URLs. It is used by HP Cloud Object Storage in addition to the `secretkey` parameter. |
|
||||
| `authversion` | no | Specify the OpenStack Auth's version, for example `3`. By default the driver autodetects the auth's version from the AuthURL. |
|
||||
| `endpointtype` | no | The endpoint type used when connecting to swift. Possible values are `public`, `internal`, and `admin`. The default is `public`. |
|
||||
|
||||
The features supported by the Swift server are queried by requesting the `/info`
|
||||
URL on the server. In case the administrator disabled that feature, the
|
||||
configuration file can specify the following optional parameters :
|
||||
|
||||
| Optional parameter | Description |
|
||||
|:--------------|:---------|
|
||||
| `tempurlcontainerkey` | Specify whether to use container secret key to generate temporary URL when set to true, or the account secret key otherwise. |
|
||||
| `tempurlmethods` | Array of HTTP methods that are supported by the TempURL middleware of the Swift server. For example: `["GET", "PUT", "HEAD", "POST", "DELETE"]` |

Additions
|
||||
---------
|
||||
|
||||
The `rs` sub project contains a wrapper for the Rackspace specific CDN Management interface.
|
||||
|
||||
Testing
|
||||
-------
|
||||
|
||||
To run the tests you can either use an embedded fake Swift server
|
||||
either use a real Openstack Swift server or a Rackspace Cloud files account.
|
||||
|
||||
When using a real Swift server, you need to set these environment variables
|
||||
before running the tests
|
||||
|
||||
export SWIFT_API_USER='user'
|
||||
export SWIFT_API_KEY='key'
|
||||
export SWIFT_AUTH_URL='https://url.of.auth.server/v1.0'
|
||||
|
||||
And optionally these if using v2 authentication
|
||||
|
||||
export SWIFT_TENANT='TenantName'
|
||||
export SWIFT_TENANT_ID='TenantId'
|
||||
|
||||
And optionally these if using v3 authentication
|
||||
|
||||
export SWIFT_TENANT='TenantName'
|
||||
export SWIFT_TENANT_ID='TenantId'
|
||||
export SWIFT_API_DOMAIN_ID='domain id'
|
||||
export SWIFT_API_DOMAIN='domain name'
|
||||
|
||||
And optionally these if using v3 trust
|
||||
|
||||
export SWIFT_TRUST_ID='TrustId'
|
||||
|
||||
And optionally this if you want to skip server certificate validation
|
||||
|
||||
export SWIFT_AUTH_INSECURE=1
|
||||
|
||||
And optionally this to configure the connect channel timeout, in seconds
|
||||
|
||||
export SWIFT_CONNECTION_CHANNEL_TIMEOUT=60
|
||||
|
||||
And optionally this to configure the data channel timeout, in seconds
|
||||
|
||||
export SWIFT_DATA_CHANNEL_TIMEOUT=60
|
||||
|
||||
Then run the tests with `go test`

/*
|
||||
Package swift provides an easy to use interface to Swift / Openstack Object Storage / Rackspace Cloud Files
|
||||
|
||||
Standard Usage
|
||||
|
||||
Most of the work is done through the Container*() and Object*() methods.
|
||||
|
||||
All methods are safe to use concurrently in multiple go routines.
|
||||
|
||||
Object Versioning
|
||||
|
||||
As defined by http://docs.openstack.org/api/openstack-object-storage/1.0/content/Object_Versioning-e1e3230.html#d6e983 one can create a container which allows for version control of files. The suggested method is to create a version container for holding all non-current files, and a current container for holding the latest version that the file points to. The container and objects inside it can be used in the standard manner, however, pushing a file multiple times will result in it being copied to the version container and the new file put in it's place. If the current file is deleted, the previous file in the version container will replace it. This means that if a file is updated 5 times, it must be deleted 5 times to be completely removed from the system.
|
||||
|
||||
Rackspace Sub Module
|
||||
|
||||
This module specifically allows the enabling/disabling of Rackspace Cloud File CDN management on a container. This is specific to the Rackspace API and not Swift/Openstack, therefore it has been placed in a submodule. One can easily create a RsConnection and use it like the standard Connection to access and manipulate containers and objects.

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?
|
||||
}
