Distribution
|
|
============
|
|
|
|
The Docker toolset to pack, ship, store, and deliver content.
|
|
|
|
The main product of this repository is the new registry implementation for
|
|
storing and distributing docker images. It supersedes the [docker/docker-
|
|
registry](https://github.com/docker/docker-registry) project with a new API
|
|
design, focused around security and performance.
|
|
|
|
The _Distribution_ project has the further long term goal of providing a
|
|
secure tool chain for distributing content. The specifications, APIs and tools
|
|
should be as useful with docker as they are without.
|
|
|
|
This repository contains the following components:
|
|
|
|
- **registry (beta):** An implementation of the [Docker Registry HTTP API
|
|
V2](doc/spec/api.md) for use with docker 1.5+.
|
|
- **libraries (unstable):** A rich set of libraries for interacting with
|
|
distribution components. Please see
|
|
[godoc](http://godoc.org/github.com/docker/distribution) for details. Note
|
|
that the libraries *are not* considered stable.
|
|
- **dist (experimental):** An experimental tool to provide distribution
|
|
oriented functionality without the docker daemon.
|
|
- **specifications**: _Distribution_ related specifications are available in
|
|
[doc/spec](doc/spec).
|
|
- **documentation:** Documentation is available in [doc](doc/overview.md).
|
|
|
|
### How will this integrate with Docker engine?
|
|
|
|
This project should provide an implementation to a V2 API for use in the
|
|
Docker core project. The API should be embeddable and simplify the process of
|
|
securely pulling and pushing content from docker daemons.
|
|
|
|
### What are the long term goals of the Distribution project?
|
|
|
|
Design a professional grade and extensible content distribution system, that
|
|
allow users to:
|
|
|
|
* Enjoy an efficient, secured and reliable way to store, manage, package and
|
|
exchange content
|
|
* Hack/roll their own on top of healthy open-source components
|
|
* Implement their own home made solution through good specs, and solid
|
|
extensions mechanism.

Features
|
|
--------
|
|
|
|
The new registry implementation provides the following benefits:
|
|
|
|
- faster push and pull
|
|
- new, more efficient implementation
|
|
- simplified deployment
|
|
- pluggable storage backend
|
|
- webhook notifications
|
|
|
|
Installation
|
|
------------
|
|
|
|
**TODO(stevvooe):** Add the following here:
|
|
- docker file
|
|
- binary builds for non-docker environment (test installations, etc.)
|
|
|
|
Configuration
|
|
-------------
|
|
|
|
The registry server can be configured with a yaml file. The following is a
|
|
simple example that can used for local development:
|
|
|
|
```yaml
|
|
version: 0.1
|
|
loglevel: debug
|
|
storage:
|
|
filesystem:
|
|
rootdirectory: /tmp/registry-dev
|
|
http:
|
|
addr: localhost:5000
|
|
secret: asecretforlocaldevelopment
|
|
debug:
|
|
addr: localhost:5001
|
|
```
|
|
|
|
The above configures the registry instance to run on port 5000, binding to
|
|
"localhost", with the debug server enabled. Registry data will be stored in
|
|
"/tmp/registry-dev". Logging will be in "debug" mode, which is the most
|
|
verbose.
|
|
|
|
A similar simple configuration is available at [cmd/registry/config.yml],
|
|
which is generally useful for local development.
|
|
|
|
**TODO(stevvooe): Need a "best practice" configuration overview. Perhaps, we
|
|
can point to a documentation section.
|
|
|
|
For full details about configuring a registry server, please see [the
|
|
documentation](doc/configuration.md).
|
|
|
|
### Upgrading
|
|
|
|
**TODO:** Add a section about upgrading from V1 registry along with link to
|
|
migrating in documentation.
|
|
|
|
Build
|
|
-----
|
|
|
|
If a go development environment is setup, one can use `go get` to install the
|
|
`registry` command from the current latest:
|
|
|
|
```sh
|
|
go get github.com/docker/distribution/cmd/registry
|
|
```
|
|
|
|
The above will install the source repository into the `GOPATH`. The `registry`
|
|
binary can then be run with the following:
|
|
|
|
```
|
|
$ $GOPATH/bin/registry -version
|
|
$GOPATH/bin/registry github.com/docker/distribution v2.0.0-alpha.1+unknown
|
|
```
|
|
|
|
The registry can be run with the default config using the following
|
|
incantantation:
|
|
|
|
```
|
|
$ $GOPATH/bin/registry $GOPATH/src/github.com/docker/distribution/cmd/registry/config.yml
|
|
INFO[0000] endpoint local-8082 disabled, skipping app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown
|
|
INFO[0000] endpoint local-8083 disabled, skipping app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown
|
|
INFO[0000] listening on :5000 app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown
|
|
INFO[0000] debug server listening localhost:5001
|
|
```
|
|
|
|
If it is working, one should see the above log messages.
|
|
|
|
### Repeatable Builds
|
|
|
|
For the full development experience, one should `cd` into
|
|
`$GOPATH/src/github.com/docker/distribution`. From there, the regular `go`
|
|
commands, such as `go test`, should work per package (please see
|
|
[Developing](#developing) if they don't work).
|
|
|
|
A `Makefile` has been provided as a convenience to support repeatable builds.
|
|
Please install the following into `GOPATH` for it to work:
|
|
|
|
```
|
|
go get github.com/tools/godep github.com/golang/lint/golint
|
|
```
|
|
|
|
**TODO(stevvooe):** Add a `make setup` command to Makefile to run this. Have
|
|
to think about how to interact with Godeps properly.
|
|
|
|
Once these commands are available in the `GOPATH`, run `make` to get a full
|
|
build:
|
|
|
|
```
|
|
$ GOPATH=`godep path`:$GOPATH make
|
|
+ clean
|
|
+ fmt
|
|
+ vet
|
|
+ lint
|
|
+ build

|
|
+ /Users/sday/go/src/github.com/docker/distribution/bin/dist
|
|
+ binaries
|
|
```
|
|
|
|
The above provides a repeatable build using the contents of the vendored
|
|
Godeps directory. This includes formatting, vetting, linting, building,
|
|
testing and generating tagged binaries. We can verify this worked by running
|
|
the registry binary generated in the "./bin" directory:
|
|
|
|
```sh
|
|
$ ./bin/registry -version
|
|
./bin/registry github.com/docker/distribution v2.0.0-alpha.2-80-g16d8b2c.m
|
|
```
|
|
|
|
### Developing
|
|
|
|
The above approaches are helpful for small experimentation. If more complex
|
|
tasks are at hand, it is recommended to employ the full power of `godep`.
|
|
|
|
The Makefile is designed to have its `GOPATH` defined externally. This allows
|
|
one to experiment with various development environment setups. This is
|
|
primarily useful when testing upstream bugfixes, by modifying local code. This
|
|
can be demonstrated using `godep` to migrate the `GOPATH` to use the specified
|
|
dependencies. The `GOPATH` can be migrated to the current package versions
|
|
declared in `Godeps` with the following command:
|
|
|
|
```sh
|
|
godep restore
|
|
```
|
|
|
|
> **WARNING:** This command will checkout versions of the code specified in
|
|
> Godeps/Godeps.json, modifying the contents of `GOPATH`. If this is
|
|
> undesired, it is recommended to create a workspace devoted to work on the
|
|
> _Distribution_ project.
|
|
|
|
With a successful run of the above command, one can now use `make` without
|
|
specifying the `GOPATH`:
|
|
|
|
```sh
|
|
$ make
|
|
```
|
|
|
|
If that is successful, standard `go` commands, such as `go test` should work,
|
|
per package, without issue.
|
|
