# Building the registry source
|
||||
|
||||
## Use-case
|
||||
|
||||
This is useful if you intend to actively work on the registry.
|
||||
|
||||
### Alternatives
|
||||
|
||||
Most people should use the [official Registry docker image](https://hub.docker.com/r/library/registry/).
|
||||
|
||||
People looking for advanced operational use cases might consider rolling their own image with a custom Dockerfile inheriting `FROM registry:2`.
|
||||
|
||||
OS X users who want to run natively can do so following [the instructions here](https://github.com/docker/docker.github.io/blob/master/registry/recipes/osx-setup-guide.md).
|
||||
|
||||
### Gotchas
|
||||
|
||||
You are expected to know your way around with go & git.
|
||||
|
||||
If you are a casual user with no development experience, and no preliminary knowledge of go, building from source is probably not a good solution for you.
|
||||
|
||||
## Build the development environment
|
||||
|
||||
The first prerequisite of properly building distribution targets is to have a Go
|
||||
development environment setup. Please follow [How to Write Go Code](https://golang.org/doc/code.html)
|
||||
for proper setup. If done correctly, you should have a GOROOT and GOPATH set in the
|
||||
environment.
|
||||
|
||||
If a Go development environment is setup, one can use `go get` to install the
|
||||
`registry` command from the current latest:
|
||||
|
||||
go get github.com/docker/distribution/cmd/registry
|
||||
|
||||
The above will install the source repository into the `GOPATH`.
|
||||
|
||||
Now create the directory for the registry data (this might require you to set permissions properly)
|
||||
|
||||
mkdir -p /var/lib/registry
|
||||
|
||||
... or alternatively `export REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY=/somewhere` if you want to store data into another location.
|
||||
|
||||
The `registry`
|
||||
binary can then be run with the following:
|
||||
|
||||
$ $GOPATH/bin/registry --version
|
||||
$GOPATH/bin/registry github.com/docker/distribution v2.0.0-alpha.1+unknown
|
||||
|
||||
> __NOTE:__ While you do not need to use `go get` to checkout the distribution
|
||||
> project, for these build instructions to work, the project must be checked
|
||||
> out in the correct location in the `GOPATH`. This should almost always be
|
||||
> `$GOPATH/src/github.com/docker/distribution`.
|
||||
|
||||
The registry can be run with the default config using the following
|
||||
incantation:
|
||||
|
||||
$ $GOPATH/bin/registry serve $GOPATH/src/github.com/docker/distribution/cmd/registry/config-example.yml
|
||||
INFO[0000] endpoint local-5003 disabled, skipping app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown
|
||||
INFO[0000] endpoint local-8083 disabled, skipping app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown
|
||||
INFO[0000] listening on :5000 app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown
|
||||
INFO[0000] debug server listening localhost:5001
|
||||
|
||||
If it is working, one should see the above log messages.
|
||||
|
||||
### Repeatable Builds
|
||||
|
||||
For the full development experience, one should `cd` into
|
||||
`$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/golang/lint/golint
|
||||
|
||||
Once these commands are available in the `GOPATH`, run `make` to get a full
|
||||
build:
|
||||
|
||||
$ make
|
||||
+ clean
|
||||
+ fmt
|
||||
+ vet
|
||||
+ lint
|
||||
+ build
|
||||
github.com/docker/docker/vendor/src/code.google.com/p/go/src/pkg/archive/tar
|
||||
github.com/sirupsen/logrus
|
||||
github.com/docker/libtrust
|
||||
...
|
||||
github.com/yvasiyarov/gorelic
|
||||
github.com/docker/distribution/registry/handlers
|
||||
github.com/docker/distribution/cmd/registry
|
||||
+ test
|
||||
...
|
||||
ok github.com/docker/distribution/digest 7.875s
|
||||
ok github.com/docker/distribution/manifest 0.028s
|
||||
ok github.com/docker/distribution/notifications 17.322s
|
||||
? github.com/docker/distribution/registry [no test files]
|
||||
ok github.com/docker/distribution/registry/api/v2 0.101s
|
||||
? github.com/docker/distribution/registry/auth [no test files]
|
||||
ok github.com/docker/distribution/registry/auth/silly 0.011s
|
||||
...
|
||||
+ /Users/sday/go/src/github.com/docker/distribution/bin/registry
|
||||
+ /Users/sday/go/src/github.com/docker/distribution/bin/registry-api-descriptor-template
|
||||
+ binaries
|
||||
|
||||
The above provides a repeatable build using the contents of the vendor
|
||||
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:
|
||||
|
||||
$ ./bin/registry --version
|
||||
./bin/registry github.com/docker/distribution v2.0.0-alpha.2-80-g16d8b2c.m
|
||||
|
||||
### Optional build tags
|
||||
|
||||
Optional [build tags](http://golang.org/pkg/go/build/) can be provided using
|
||||
the environment variable `DOCKER_BUILDTAGS`.

# Contributing to the registry
|
||||
|
||||
## Before reporting an issue...
|
||||
|
||||
### If your problem is with...
|
||||
|
||||
- automated builds
|
||||
- your account on the [Docker Hub](https://hub.docker.com/)
|
||||
- any other [Docker Hub](https://hub.docker.com/) issue
|
||||
|
||||
Then please do not report your issue here - you should instead report it to [https://support.docker.com](https://support.docker.com)
|
||||
|
||||
### If you...
|
||||
|
||||
- need help setting up your registry
|
||||
- can't figure out something
|
||||
- are not sure what's going on or what your problem is
|
||||
|
||||
Then please do not open an issue here yet - you should first try one of the following support forums:
|
||||
|
||||
- irc: #docker-distribution on freenode
|
||||
- mailing-list: <distribution@dockerproject.org> or https://groups.google.com/a/dockerproject.org/forum/#!forum/distribution
|
||||
|
||||
### Reporting security issues
|
||||
|
||||
The Docker maintainers take security seriously. If you discover a security
|
||||
issue, please bring it to their attention right away!
|
||||
|
||||
Please **DO NOT** file a public issue, instead send your report privately to
|
||||
[security@docker.com](mailto:security@docker.com).
|
||||
|
||||
## Reporting an issue properly
|
||||
|
||||
By following these simple rules you will get better and faster feedback on your issue.
|
||||
|
||||
- search the bugtracker for an already reported issue
|
||||
|
||||
### If you found an issue that describes your problem:
|
||||
|
||||
- please read other user comments first, and confirm this is the same issue: a given error condition might be indicative of different problems - you may also find a workaround in the comments
|
||||
- please refrain from adding "same thing here" or "+1" comments
|
||||
- you don't need to comment on an issue to get notified of updates: just hit the "subscribe" button
|
||||
- comment if you have some new, technical and relevant information to add to the case
|
||||
- __DO NOT__ comment on closed issues or merged PRs. If you think you have a related problem, open up a new issue and reference the PR or issue.
|
||||
|
||||
### If you have not found an existing issue that describes your problem:
|
||||
|
||||
1. create a new issue, with a succinct title that describes your issue:
|
||||
- bad title: "It doesn't work with my docker"
|
||||
- good title: "Private registry push fail: 400 error with E_INVALID_DIGEST"
|
||||
2. copy the output of:
|
||||
- `docker version`
|
||||
- `docker info`
|
||||
- `docker exec <registry-container> registry --version`
|
||||
3. copy the command line you used to launch your Registry
|
||||
4. restart your docker daemon in debug mode (add `-D` to the daemon launch arguments)
|
||||
5. reproduce your problem and get your docker daemon logs showing the error
|
||||
6. if relevant, copy your registry logs that show the error
|
||||
7. provide any relevant detail about your specific Registry configuration (e.g., storage backend used)
|
||||
8. indicate if you are using an enterprise proxy, Nginx, or anything else between you and your Registry
|
||||
|
||||
## Contributing a patch for a known bug, or a small correction
|
||||
|
||||
You should follow the basic GitHub workflow:
|
||||
|
||||
1. fork
|
||||
2. commit a change
|
||||
3. make sure the tests pass
|
||||
4. PR
|
||||
|
||||
Additionally, you must [sign your commits](https://github.com/docker/docker/blob/master/CONTRIBUTING.md#sign-your-work). It's very simple:
|
||||
|
||||
- configure your name with git: `git config user.name "Real Name" && git config user.email mail@example.com`
|
||||
- sign your commits using `-s`: `git commit -s -m "My commit"`
|
||||
|
||||
Some simple rules to ensure quick merge:
|
||||
|
||||
- clearly point to the issue(s) you want to fix in your PR comment (e.g., `closes #12345`)
|
||||
- prefer multiple (smaller) PRs addressing individual issues over a big one trying to address multiple issues at once
|
||||
- if you need to amend your PR following comments, please squash instead of adding more commits
|
||||
|
||||
## Contributing new features
|
||||
|
||||
You are heavily encouraged to first discuss what you want to do. You can do so on the irc channel, or by opening an issue that clearly describes the use case you want to fulfill, or the problem you are trying to solve.
|
||||
|
||||
If this is a major new feature, you should then submit a proposal that describes your technical solution and reasoning.
|
||||
If you did discuss it first, this will likely be greenlighted very fast. It's advisable to address all feedback on this proposal before starting actual work.
|
||||
|
||||
Then you should submit your implementation, clearly linking to the issue (and possible proposal).
|
||||
|
||||
Your PR will be reviewed by the community, then ultimately by the project maintainers, before being merged.
|
||||
|
||||
It's mandatory to:
|
||||
|
||||
- interact respectfully with other community members and maintainers - more generally, you are expected to abide by the [Docker community rules](https://github.com/docker/docker/blob/master/CONTRIBUTING.md#docker-community-guidelines)
|
||||
- address maintainers' comments and modify your submission accordingly
|
||||
- write tests for any new code
|
||||
|
||||
Complying to these simple rules will greatly accelerate the review process, and will ensure you have a pleasant experience in contributing code to the Registry.
|
||||
|
||||
Have a look at a great, successful contribution: the [Swift driver PR](https://github.com/docker/distribution/pull/493)
|
||||
|
||||
## Coding Style
|
||||
|
||||
Unless explicitly stated, we follow all coding guidelines from the Go
|
||||
community. While some of these standards may seem arbitrary, they somehow seem
|
||||
to result in a solid, consistent codebase.
|
||||
|
||||
It is possible that the code base does not currently comply with these
|
||||
guidelines. We are not looking for a massive PR that fixes this, since that
|
||||
goes against the spirit of the guidelines. All new contributions should make a
|
||||
best effort to clean up and make the code base better than they left it.
|
||||
Obviously, apply your best judgement. Remember, the goal here is to make the
|
||||
code base easier for humans to navigate and understand. Always keep that in
|
||||
mind when nudging others to comply.
|
||||
|
||||
The rules:
|
||||
|
||||
1. All code should be formatted with `gofmt -s`.
|
||||
2. All code should pass the default levels of
|
||||
[`golint`](https://github.com/golang/lint).
|
||||
3. All code should follow the guidelines covered in [Effective
|
||||
Go](http://golang.org/doc/effective_go.html) and [Go Code Review
|
||||
Comments](https://github.com/golang/go/wiki/CodeReviewComments).
|
||||
4. Comment the code. Tell us the why, the history and the context.
|
||||
5. Document _all_ declarations and methods, even private ones. Declare
|
||||
expectations, caveats and anything else that may be important. If a type
|
||||
gets exported, having the comments already there will ensure it's ready.
|
||||
6. Variable name length should be proportional to its context and no longer.
|
||||
`noCommaALongVariableNameLikeThisIsNotMoreClearWhenASimpleCommentWouldDo`.
|
||||
In practice, short methods will have short variable names and globals will
|
||||
have longer names.
|
||||
7. No underscores in package names. If you need a compound name, step back,
|
||||
and re-examine why you need a compound name. If you still think you need a
|
||||
compound name, lose the underscore.
|
||||
8. No utils or helpers packages. If a function is not general enough to
|
||||
warrant its own package, it has not been written generally enough to be a
|
||||
part of a util package. Just leave it unexported and well-documented.
|
||||
9. All tests should run with `go test` and outside tooling should not be
|
||||
required. No, we don't need another unit testing framework. Assertion
|
||||
packages are acceptable if they provide _real_ incremental value.
|
||||
10. Even though we call these "rules" above, they are actually just
|
||||
guidelines. Since you've read all the rules, you now know that.
|
||||
|
||||
If you are having trouble getting into the mood of idiomatic Go, we recommend
|
||||
reading through [Effective Go](http://golang.org/doc/effective_go.html). The
|
||||
[Go Blog](http://blog.golang.org/) is also a great resource. Drinking the
|
||||
kool-aid is a lot easier than going thirsty.

Maintainers are often under-appreciated, because their work is harder to appreciate.

It's easy to appreciate a really cool and technically advanced feature. It's harder

to appreciate the absence of bugs, the slow but steady improvement in stability,

maintainer candidates are selected and proposed on the maintainers mailing list.

existing maintainers are given five business days to discuss the candidate,

raise objections and cast their vote. Candidates must be approved by at least 66% of the current maintainers by adding their vote on the mailing

allowed to vote.

If a candidate is approved, a maintainer will contact the candidate to invite

Short answer: EVERYTHING IS A PULL REQUEST.

distribution is an open-source project with an open design philosophy. This means

that the repository is the source of truth for EVERY aspect of the project,

including its philosophy, design, road map, and APIs. *If it's part of the
|
||||
project, it's in the repo. If it's in the repo, it's part of the project.*

||||
As a result, all decisions can be expressed as changes to the repository. An
|
||||
implementation change is a change to the source code. An API change is a change
|
||||
to the API specification. A philosophy change is a change to the philosophy
|
||||
manifesto, and so on.
|
||||
|

All decisions affecting distribution, big and small, follow the same 3 steps:

|

|
||||
* Step 2: Discuss the pull request. Anyone can do this.

of the pull request and which areas of the project it affects.

# Distribution
|
||||
|
||||
The Docker toolset to pack, ship, store, and deliver content.
|
||||
|
||||
This repository provides the Docker Registry 2.0 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.
|
||||
|
||||

|
||||
|
||||
[](https://circleci.com/gh/docker/distribution/tree/master)
|
||||
[](https://godoc.org/github.com/docker/distribution)
|
||||
|
||||
This repository contains the following components:
|
||||
|
||||
|**Component** |Description |
|
||||
|--------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
||||
| **registry** | An implementation of the [Docker Registry HTTP API V2](docs/spec/api.md) for use with docker 1.6+. |
|
||||
| **libraries** | A rich set of libraries for interacting with distribution components. Please see [godoc](https://godoc.org/github.com/docker/distribution) for details. **Note**: These libraries are **unstable**. |
|
||||
| **specifications** | _Distribution_ related specifications are available in [docs/spec](docs/spec) |
|
||||
| **documentation** | Docker's full documentation set is available at [docs.docker.com](https://docs.docker.com). This repository [contains the subset](docs/) related just to the registry. |
|
||||
|
||||
### How does this integrate with Docker engine?
|
||||
|
||||
This project should provide an implementation to a V2 API for use in the [Docker
|
||||
core project](https://github.com/docker/docker). 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?
|
||||
|
||||
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.
|
||||
|
||||
Our goal is to 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.
|
||||
|
||||
## More about Registry 2.0
|
||||
|
||||
The new registry implementation provides the following benefits:
|
||||
|
||||
- faster push and pull
|
||||
- new, more efficient implementation
|
||||
- simplified deployment
|
||||
- pluggable storage backend
|
||||
- webhook notifications
|
||||
|
||||
For information on upcoming functionality, please see [ROADMAP.md](ROADMAP.md).
|
||||
|
||||
### Who needs to deploy a registry?
|
||||
|
||||
By default, Docker users pull images from Docker's public registry instance.
|
||||
[Installing Docker](https://docs.docker.com/engine/installation/) gives users this
|
||||
ability. Users can also push images to a repository on Docker's public registry,
|
||||
if they have a [Docker Hub](https://hub.docker.com/) account.
|
||||
|
||||
For some users and even companies, this default behavior is sufficient. For
|
||||
others, it is not.
|
||||
|
||||
For example, users with their own software products may want to maintain a
|
||||
registry for private, company images. Also, you may wish to deploy your own
|
||||
image repository for images used to test or in continuous integration. For these
|
||||
use cases and others, [deploying your own registry instance](https://github.com/docker/docker.github.io/blob/master/registry/deploying.md)
|
||||
may be the better choice.
|
||||
|
||||
### Migration to Registry 2.0
|
||||
|
||||
For those who have previously deployed their own registry based on the Registry
|
||||
1.0 implementation and wish to deploy a Registry 2.0 while retaining images,
|
||||
data migration is required. A tool to assist with migration efforts has been
|
||||
created. For more information see [docker/migrator](https://github.com/docker/migrator).

# Roadmap
|
||||
|
||||
The Distribution Project consists of several components, some of which are
|
||||
still being defined. This document defines the high-level goals of the
|
||||
project, identifies the current components, and defines the release-
|
||||
relationship to the Docker Platform.
|
||||
|
||||
* [Distribution Goals](#distribution-goals)
|
||||
* [Distribution Components](#distribution-components)
|
||||
* [Project Planning](#project-planning): release-relationship to the Docker Platform.
|
||||
|
||||
This road map is a living document, providing an overview of the goals and
|
||||
considerations made in respect of the future of the project.
|
||||
|
||||
## Distribution Goals
|
||||
|
||||
- Replace the existing [docker registry](github.com/docker/docker-registry)
|
||||
implementation as the primary implementation.
|
||||
- Replace the existing push and pull code in the docker engine with the
|
||||
distribution package.
|
||||
- Define a strong data model for distributing docker images
|
||||
- Provide a flexible distribution tool kit for use in the docker platform
|
||||
- Unlock new distribution models
|
||||
|
||||
## Distribution Components
|
||||
|
||||
Components of the Distribution Project are managed via github [milestones](https://github.com/docker/distribution/milestones). Upcoming
|
||||
features and bugfixes for a component will be added to the relevant milestone. If a feature or
|
||||
bugfix is not part of a milestone, it is currently unscheduled for
|
||||
implementation.

|
||||
### Registry
|
||||
|
||||
The new Docker registry is the main portion of the distribution repository.
|
||||
Registry 2.0 is the first release of the next-generation registry. This was
|
||||
primarily focused on implementing the [new registry
|
||||
API](https://github.com/docker/distribution/blob/master/docs/spec/api.md),
|
||||
with a focus on security and performance.
|
||||
|
||||
Following from the Distribution project goals above, we have a set of goals
|
||||
for registry v2 that we would like to follow in the design. New features
|
||||
should be compared against these goals.
|
||||
|
||||
#### Data Storage and Distribution First
|
||||
|
||||
The registry's first goal is to provide a reliable, consistent storage
|
||||
location for Docker images. The registry should only provide the minimal
|
||||
amount of indexing required to fetch image data and no more.
|
||||
|
||||
This means we should be selective in new features and API additions, including
|
||||
those that may require expensive, ever growing indexes. Requests should be
|
||||
servable in "constant time".
|
||||
|
||||
#### Content Addressability
|
||||
|
||||
All data objects used in the registry API should be content addressable.
|
||||
Content identifiers should be secure and verifiable. This provides a secure,
|
||||
reliable base from which to build more advanced content distribution systems.
|
||||
|
||||
#### Content Agnostic
|
||||
|
||||
In the past, changes to the image format would require large changes in Docker
|
||||
and the Registry. By decoupling the distribution and image format, we can
|
||||
allow the formats to progress without having to coordinate between the two.
|
||||
This means that we should be focused on decoupling Docker from the registry
|
||||
just as much as decoupling the registry from Docker. Such an approach will
|
||||
allow us to unlock new distribution models that haven't been possible before.
|
||||
|
||||
We can take this further by saying that the new registry should be content
|
||||
agnostic. The registry provides a model of names, tags, manifests and content
|
||||
addresses and that model can be used to work with content.
|
||||
|
||||
#### Simplicity
|
||||
|
||||
The new registry should be closer to a microservice component than its
|
||||
predecessor. This means it should have a narrower API and a low number of
|
||||
service dependencies. It should be easy to deploy.
|
||||
|
||||
This means that other solutions should be explored before changing the API or
|
||||
adding extra dependencies. If functionality is required, can it be added as an
|
||||
extension or companion service.
|
||||
|
||||
#### Extensibility
|
||||
|
||||
The registry should provide extension points to add functionality. By keeping
|
||||
the scope narrow, but providing the ability to add functionality.
|
||||
|
||||
Features like search, indexing, synchronization and registry explorers fall
|
||||
into this category. No such feature should be added unless we've found it
|
||||
impossible to do through an extension.
|
||||
|
||||
#### Active Feature Discussions
|
||||
|
||||
The following are feature discussions that are currently active.
|
||||
|
||||
If you don't see your favorite, unimplemented feature, feel free to contact us
|
||||
via IRC or the mailing list and we can talk about adding it. The goal here is
|
||||
to make sure that new features go through a rigid design process before
|
||||
landing in the registry.
|
||||
|
||||
##### Proxying to other Registries
|
||||
|
||||
A _pull-through caching_ mode exists for the registry, but is restricted from
|
||||
within the docker client to only mirror the official Docker Hub. This functionality
|
||||
can be expanded when image provenance has been specified and implemented in the
|
||||
distribution project.
|
||||
|
||||
##### Metadata storage
|
||||
|
||||
Metadata for the registry is currently stored with the manifest and layer data on
|
||||
the storage backend. While this is a big win for simplicity and reliably maintaining
|
||||
state, it comes with the cost of consistency and high latency. The mutable registry
|
||||
metadata operations should be abstracted behind an API which will allow ACID compliant
|
||||
storage systems to handle metadata.
|
||||
|
||||
##### Peer to Peer transfer
|
||||
|
||||
Discussion has started here: https://docs.google.com/document/d/1rYDpSpJiQWmCQy8Cuiaa3NH-Co33oK_SC9HeXYo87QA/edit
|
||||
|
||||
##### Indexing, Search and Discovery
|
||||
|
||||
The original registry provided some implementation of search for use with
|
||||
private registries. Support has been elided from V2 since we'd like to both
|
||||
decouple search functionality from the registry. The makes the registry
|
||||
simpler to deploy, especially in use cases where search is not needed, and
|
||||
let's us decouple the image format from the registry.
|
||||
|
||||
There are explorations into using the catalog API and notification system to
|
||||
build external indexes. The current line of thought is that we will define a
|
||||
common search API to index and query docker images. Such a system could be run
|
||||
as a companion to a registry or set of registries to power discovery.
|
||||
|
||||
The main issue with search and discovery is that there are so many ways to
|
||||
accomplish it. There are two aspects to this project. The first is deciding on
|
||||
how it will be done, including an API definition that can work with changing
|
||||
data formats. The second is the process of integrating with `docker search`.
|
||||
We expect that someone attempts to address the problem with the existing tools
|
||||
and propose it as a standard search API or uses it to inform a standardization
|
||||
process. Once this has been explored, we integrate with the docker client.
|
||||
|
||||
Please see the following for more detail:
|
||||

||||

|
||||
|
||||
##### Deletes
|
||||
|
||||
> __NOTE:__ Deletes are a much asked for feature. Before requesting this
|
||||
feature or participating in discussion, we ask that you read this section in
|
||||
full and understand the problems behind deletes.
|
||||
|
||||
While, at first glance, implementing deleting seems simple, there are a number
|
||||
mitigating factors that make many solutions not ideal or even pathological in
|
||||
the context of a registry. The following paragraph discuss the background and
|
||||
approaches that could be applied to arrive at a solution.
|
||||
|
||||
The goal of deletes in any system is to remove unused or unneeded data. Only
|
||||
data requested for deletion should be removed and no other data. Removing
|
||||
unintended data is worse than _not_ removing data that was requested for
|
||||
removal but ideally, both are supported. Generally, according to this rule, we
|
||||
err on holding data longer than needed, ensuring that it is only removed when
|
||||
we can be certain that it can be removed. With the current behavior, we opt to
|
||||
hold onto the data forever, ensuring that data cannot be incorrectly removed.
|
||||
|
||||
To understand the problems with implementing deletes, one must understand the
|
||||
data model. All registry data is stored in a filesystem layout, implemented on
|
||||
a "storage driver", effectively a _virtual file system_ (VFS). The storage
|
||||
system must assume that this VFS layer will be eventually consistent and has
|
||||
poor read- after-write consistency, since this is the lower common denominator
|
||||
among the storage drivers. This is mitigated by writing values in reverse-
|
||||
dependent order, but makes wider transactional operations unsafe.
|
||||
|
||||
Layered on the VFS model is a content-addressable _directed, acyclic graph_
|
||||
(DAG) made up of blobs. Manifests reference layers. Tags reference manifests.
|
||||
Since the same data can be referenced by multiple manifests, we only store
|
||||
data once, even if it is in different repositories. Thus, we have a set of
|
||||
blobs, referenced by tags and manifests. If we want to delete a blob we need
|
||||
to be certain that it is no longer referenced by another manifest or tag. When
|
||||
we delete a manifest, we also can try to delete the referenced blobs. Deciding
|
||||
whether or not a blob has an active reference is the crux of the problem.
|
||||
|
||||
Conceptually, deleting a manifest and its resources is quite simple. Just find
|
||||
all the manifests, enumerate the referenced blobs and delete the blobs not in
|
||||
that set. An astute observer will recognize this as a garbage collection
|
||||
problem. As with garbage collection in programming languages, this is very
|
||||
simple when one always has a consistent view. When one adds parallelism and an
|
||||
inconsistent view of data, it becomes very challenging.
|
||||
|
||||
A simple example can demonstrate this. Let's say we are deleting a manifest
|
||||
_A_ in one process. We scan the manifest and decide that all the blobs are
|
||||
ready for deletion. Concurrently, we have another process accepting a new
|
||||
manifest _B_ referencing one or more blobs from the manifest _A_. Manifest _B_
|
||||
is accepted and all the blobs are considered present, so the operation
|
||||
proceeds. The original process then deletes the referenced blobs, assuming
|
||||
they were unreferenced. The manifest _B_, which we thought had all of its data
|
||||
present, can no longer be served by the registry, since the dependent data has
|
||||
been deleted.
|
||||
|
||||
Deleting data from the registry safely requires some way to coordinate this
|
||||
operation. The following approaches are being considered:
|
||||
|
||||
- _Reference Counting_ - Maintain a count of references to each blob. This is
|
||||
challenging for a number of reasons: 1. maintaining a consistent consensus
|
||||
of reference counts across a set of Registries and 2. Building the initial
|
||||
list of reference counts for an existing registry. These challenges can be
|
||||
met with a consensus protocol like Paxos or Raft in the first case and a
|
||||
necessary but simple scan in the second..
|
||||
- _Lock the World GC_ - Halt all writes to the data store. Walk the data store
|
||||
and find all blob references. Delete all unreferenced blobs. This approach
|
||||
is very simple but requires disabling writes for a period of time while the
|
||||
service reads all data. This is slow and expensive but very accurate and
|
||||
effective.
|
||||
- _Generational GC_ - Do something similar to above but instead of blocking
|
||||
writes, writes are sent to another storage backend while reads are broadcast
|
||||
to the new and old backends. GC is then performed on the read-only portion.
|
||||
Because writes land in the new backend, the data in the read-only section
|
||||
can be safely deleted. The main drawbacks of this approach are complexity
|
||||
and coordination.
|
||||
- _Centralized Oracle_ - Using a centralized, transactional database, we can
|
||||
know exactly which data is referenced at any given time. This avoids
|
||||
coordination problem by managing this data in a single location. We trade
|
||||
off metadata scalability for simplicity and performance. This is a very good
|
||||
option for most registry deployments. This would create a bottleneck for
|
||||
registry metadata. However, metadata is generally not the main bottleneck
|
||||
when serving images.
|
||||
|
||||
Please let us know if other solutions exist that we have yet to enumerate.
|
||||
Note that for any approach, implementation is a massive consideration. For
|
||||
example, a mark-sweep based solution may seem simple but the amount of work in
|
||||
coordination offset the extra work it might take to build a _Centralized
|
||||
Oracle_. We'll accept proposals for any solution but please coordinate with us
|
||||
before dropping code.
|
||||
|
||||
At this time, we have traded off simplicity and ease of deployment for disk
|
||||
space. Simplicity and ease of deployment tend to reduce developer involvement,
|
||||
which is currently the most expensive resource in software engineering. Taking
|
||||
on any solution for deletes will greatly effect these factors, trading off
|
||||
very cheap disk space for a complex deployment and operational story.

### Distribution Package
|
||||
|
||||
At its core, the Distribution Project is a set of Go packages that make up
|
||||
Distribution Components. At this time, most of these packages make up the
|
||||
Registry implementation.
|
||||
|
||||
The package itself is considered unstable. If you're using it, please take care to vendor the dependent version.
|
||||
|
||||
For feature additions, please see the Registry section. In the future, we may break out a
|
||||
separate Roadmap for distribution-specific features that apply to more than
|
||||
just the registry.
|
||||
|
||||
***
|
||||
|
||||
### Project Planning
|
||||
|
||||
An [Open-Source Planning Process](https://github.com/docker/distribution/wiki/Open-Source-Planning-Process) is used to define the Roadmap. [Project Pages](https://github.com/docker/distribution/wiki) define the goals for each Milestone and identify current progress.
