# Contributing to Docker
Want to hack on Docker? Awesome! We have a contributor's guide that explains
[setting up a Docker development environment and the contribution
process](https://docs.docker.com/project/who-written-for/).
Want to hack on Docker? Awesome! There are instructions to get you
started on the website: http://docker.io/gettingstarted.html
![Contributors guide](docs/static_files/contributors.png)
They are probably not perfect, please let us know if anything feels
wrong or incomplete.
This page contains information about reporting issues as well as some tips and
guidelines useful to experienced open source contributors. Finally, make sure
you read our [community guidelines](#docker-community-guidelines) before you
start participating.
## Contribution guidelines
## Topics
### Pull requests are always welcome
* [Reporting Security Issues](#reporting-security-issues)
* [Design and Cleanup Proposals](#design-and-cleanup-proposals)
* [Reporting Issues](#reporting-other-issues)
* [Quick Contribution Tips and Guidelines](#quick-contribution-tips-and-guidelines)
* [Community Guidelines](#docker-community-guidelines)
We are always thrilled to receive pull requests, and do our best to
process them as fast as possible. Not sure if that typo is worth a pull
request? Do it! We will appreciate it.
## Reporting security issues
If your pull request is not accepted on the first try, don't be
discouraged! If there's a problem with the implementation, hopefully you
received feedback on what to improve.
The Docker maintainers take security seriously. If you discover a security
issue, please bring it to their attention right away!
We're trying very hard to keep Docker lean and focused. We don't want it
to do everything for everybody. This means that we might decide against
incorporating a new feature. However, there might be a way to implement
that feature *on top of* docker.
Please **DO NOT** file a public issue, instead send your report privately to
[security@docker.com](mailto:security@docker.com).
### Discuss your design on the mailing list
Security reports are greatly appreciated and we will publicly thank you for it.
We also like to send gifts&mdash;if you're into Docker schwag, make sure to let
us know. We currently do not offer a paid security bounty program, but are not
ruling it out in the future.
We recommend discussing your plans [on the mailing
list](https://groups.google.com/forum/?fromgroups#!forum/docker-club)
before starting to code - especially for more ambitious contributions.
This gives other contributors a chance to point you in the right
direction, give feedback on your design, and maybe point out if someone
else is working on the same thing.
### Create issues...
## Reporting other issues
Any significant improvement should be documented as [a github
issue](https://github.com/dotcloud/docker/issues) before anybody
starts working on it.
A great way to contribute to the project is to send a detailed report when you
encounter an issue. We always appreciate a well-written, thorough bug report,
and will thank you for it!
Check that [our issue database](https://github.com/docker/docker/issues)
doesn't already include that problem or suggestion before submitting an issue.
If you find a match, add a quick "+1" or "I have this problem too." Doing this
helps prioritize the most common problems and requests. **DO NOT DO THAT** to
subscribe to the issue unless you have something meaningful to add to the
conversation. The best way to subscribe the issue is by clicking Subscribe
button in top right of the page.
When reporting issues, please include your host OS (Ubuntu 12.04, Fedora 19,
etc). Please include:
* The output of `uname -a`.
* The output of `docker version`.
* The output of `docker info`.
Please also include the steps required to reproduce the problem if possible and
applicable. This information will help us review and fix your issue faster.
**Issue Report Template**:
```
Description of problem:
`docker version`:
`docker info`:
`uname -a`:
Environment details (AWS, VirtualBox, physical, etc.):
How reproducible:
Steps to Reproduce:
1.

##Quick contribution tips and guidelines
This section gives the experienced contributor some tips and guidelines.
###Pull requests are always welcome
Not sure if that typo is worth a pull request? Found a bug and know how to fix
it? Do it! We will appreciate it. Any significant improvement should be
documented as [a GitHub issue](https://github.com/docker/docker/issues) before
anybody starts working on it.
We are always thrilled to receive pull requests. We do our best to process them
quickly. If your pull request is not accepted on the first try,
don't get discouraged! Our contributor's guide explains [the review process we
use for simple changes](https://docs.docker.com/project/make-a-contribution/).
### Design and cleanup proposals
You can propose new designs for existing Docker features. You can also design
entirely new features. We really appreciate contributors who want to refactor or
otherwise cleanup our project. For information on making these types of
contributions, see [the advanced contribution
section](https://docs.docker.com/project/advanced-contributing/) in the
contributors guide.
We try hard to keep Docker lean and focused. Docker can't do everything for
everybody. This means that we might decide against incorporating a new feature.
However, there might be a way to implement that feature *on top of* Docker.

### ...but check for existing issues first!
Please take a moment to check that an issue doesn't already exist
documenting your bug report or improvement proposal. If it does, it
never hurts to add a quick "+1" or "I have this problem too". This will
help prioritize the most common problems and requests.
### Conventions
Fork the repository and make changes on your fork in a feature branch:
Fork the repo and make changes on your fork in a feature branch:
- If it's a bug fix branch, name it XXXX-something where XXXX is the number of
the issue.
- If it's a feature branch, create an enhancement issue to announce
your intentions, and name it XXXX-something where XXXX is the number of the
issue.
- If it's a bugfix branch, name it XXX-something where XXX is the number of the
issue
- If it's a feature branch, create an enhancement issue to announce your
intentions, and name it XXX-something where XXX is the number of the issue.
Submit unit tests for your changes. Go has a great test framework built in; use
it! Take a look at existing tests for inspiration. [Run the full test
suite](https://docs.docker.com/project/test-and-docs/) on your branch before
submitting a pull request.
Submit unit tests for your changes. Go has a great test framework built in; use
it! Take a look at existing tests for inspiration. Run the full test suite on
your branch before submitting a pull request.
Update the documentation when creating or modifying features. Test your
documentation changes for clarity, concision, and correctness, as well as a
clean documentation build. See our contributors guide for [our style
guide](https://docs.docker.com/project/doc-style) and instructions on [building
the documentation](https://docs.docker.com/project/test-and-docs/#build-and-test-the-documentation).
Make sure you include relevant updates or additions to documentation when
creating or modifying features.
Write clean code. Universally formatted code promotes ease of writing, reading,
and maintenance. Always run `gofmt -s -w file.go` on each changed file before
committing your changes. Most editors have plug-ins that do this automatically.
and maintenance. Always run `go fmt` before committing your changes. Most
editors have plugins that do this automatically, and there's also a git
pre-commit hook:
Pull request descriptions should be as clear as possible and include a reference
to all the issues that they address.
```
curl -o .git/hooks/pre-commit https://raw.github.com/edsrzf/gofmt-git-hook/master/fmt-check && chmod +x .git/hooks/pre-commit
```
Commit messages must start with a capitalized and short summary (max. 50 chars)
written in the imperative, followed by an optional, more detailed explanatory
text which is separated from the summary by an empty line.
Pull requests descriptions should be as clear as possible and include a
reference to all the issues that they address.
Code review comments may be added to your pull request. Discuss, then make the
suggested modifications and push additional commits to your feature branch. Post
a comment after pushing. New commits show up in the pull request automatically,
but the reviewers are notified only when you comment.
suggested modifications and push additional commits to your feature branch. Be
sure to post a comment after pushing. The new commits will show up in the pull
request automatically, but the reviewers will not be notified unless you
comment.
Pull requests must be cleanly rebased on top of master without multiple branches
mixed into the PR.
Before the pull request is merged, make sure that you squash your commits into
logical units of work using `git rebase -i` and `git push -f`. After every
commit the test suite should be passing. Include documentation changes in the
same commit so that a revert would remove all traces of the feature or fix.
**Git tip**: If your PR no longer merges cleanly, use `rebase master` in your
feature branch to update your pull request rather than `merge master`.
Commits that fix or close an issue should include a reference like `Closes #XXX`
or `Fixes #XXX`, which will automatically close the issue when merged.
Before you make a pull request, squash your commits into logical units of work
using `git rebase -i` and `git push -f`. A logical unit of work is a consistent
set of patches that should be reviewed together: for example, upgrading the
version of a vendored dependency and taking advantage of its now available new
feature constitute two separate units of work. Implementing a new function and
calling it in another file constitute a single logical unit of work. The very
high majority of submissions should have a single commit, so if in doubt: squash
down to one.
After every commit, [make sure the test suite passes]
(https://docs.docker.com/project/test-and-docs/). Include documentation
changes in the same pull request so that a revert would remove all traces of
the feature or fix.
Include an issue reference like `Closes #XXXX` or `Fixes #XXXX` in commits that
close an issue. Including references automatically closes the issue on a merge.
Please do not add yourself to the `AUTHORS` file, as it is regenerated regularly
from the Git history.
Please see the [Coding Style](#coding-style) for further guidelines.
### Merge approval
Docker maintainers use LGTM (Looks Good To Me) in comments on the code review to
indicate acceptance.
A change requires LGTMs from an absolute majority of the maintainers of each
component affected. For example, if a change affects `docs/` and `registry/`, it
needs an absolute majority from the maintainers of `docs/` AND, separately, an
absolute majority of the maintainers of `registry/`.
For more details, see the [MAINTAINERS](MAINTAINERS) page.
### 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'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`.
Note that the old-style `Docker-DCO-1.1-Signed-off-by: ...` format is still
accepted, so there is no need to update outstanding pull requests to the new
format right away, but please do adjust your processes for future contributions.
### How can I become a maintainer?
* Step 1: Learn the component inside out
* Step 2: Make yourself useful by contributing code, bug fixes, support etc.
* Step 3: Volunteer on the IRC channel (#docker at Freenode)
* Step 4: Propose yourself at a scheduled docker meeting in #docker-dev
Don't forget: being a maintainer is a time investment. Make sure you
will have time to make yourself available. You don't have to be a
maintainer to make a difference on the project!
### IRC meetings
There are two monthly meetings taking place on #docker-dev IRC to accommodate all
timezones. Anybody can propose a topic for discussion prior to the meeting.
If you feel the conversation is going off-topic, feel free to point it out.
For the exact dates and times, have a look at [the irc-minutes
repo](https://github.com/docker/irc-minutes). The minutes also contain all the
notes from previous meetings.
## Docker community guidelines
We want to keep the Docker community awesome, growing and collaborative. We need
your help to keep it that way. To help with this we've come up with some general
guidelines for the community as a whole:
* Be nice: Be courteous, respectful and polite to fellow community members:
no regional, racial, gender, or other abuse will be tolerated. We like
nice people way better than mean ones!
* Encourage diversity and participation: Make everyone in our community feel
welcome, regardless of their background and the extent of their
contributions, and do everything possible to encourage participation in
our community.
* Keep it legal: Basically, don't get us in trouble. Share only content that
you own, do not share private or sensitive information, and don't break
the law.
* Stay on topic: Make sure that you are posting to the correct channel and
avoid off-topic discussions. Remember when you update an issue or respond
to an email you are potentially sending to a large number of people. Please
consider this before you update. Also remember that nobody likes spam.
### Guideline violations — 3 strikes method
The point of this section is not to find opportunities to punish people, but we
do need a fair way to deal with people who are making our community suck.
1. First occurrence: We'll give you a friendly, but public reminder that the
behavior is inappropriate according to our guidelines.
2. Second occurrence: We will send you a private message with a warning that
any additional violations will result in removal from the community.
3. Third occurrence: Depending on the violation, we may need to delete or ban
your account.
**Notes:**
* Obvious spammers are banned on first occurrence. If we don't do this, we'll
have spam all over the place.
* Violations are forgiven after 6 months of good behavior, and we won't hold a
grudge.
* People who commit minor infractions will get some education, rather than
hammering them in the 3 strikes process.
* The rules apply equally to everyone in the community, no matter how much
you've contributed.
* Extreme violations of a threatening, abusive, destructive or illegal nature
will be addressed immediately and are not subject to 3 strikes or forgiveness.
* Contact abuse@docker.com to report abuse or appeal violations. In the case of
appeals, we know that mistakes happen, and we'll work with you to come up with a
fair solution if there has been a misunderstanding.
## 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 it's 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 it's 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.
Add your name to the AUTHORS file, but make sure the list is sorted and your
name and email address match your git configuration. The AUTHORS file is
regenerated occasionally from the git commit history, so a mismatch may result
in your changes being overwritten.

[Rules.maintainers]
title = "What is a maintainer?"
text = """
There are different types of maintainers, with different responsibilities, but
all maintainers have 3 things in common:
1) They share responsibility in the project's success.
2) They have made a long-term, recurring time investment to improve the project.
3) They spend that time doing whatever needs to be done, not necessarily what
is the most interesting or fun.
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,
or the reliability of a release process. But those things distinguish a good
project from a great one.
"""
[Rules.bdfl]
title = "The Benevolent dictator for life (BDFL)"
text = """
Docker follows the timeless, highly efficient and totally unfair system
known as [Benevolent dictator for
life](https://en.wikipedia.org/wiki/Benevolent_Dictator_for_Life), with
yours truly, Solomon Hykes, in the role of BDFL. This means that all
decisions are made, by default, by Solomon. Since making every decision
myself would be highly un-scalable, in practice decisions are spread
across multiple maintainers.
Ideally, the BDFL role is like the Queen of England: awesome crown, but not
an actual operational role day-to-day. The real job of a BDFL is to NEVER GO AWAY.
Every other rule can change, perhaps drastically so, but the BDFL will always
be there, preserving the philosophy and principles of the project, and keeping
ultimate authority over its fate. This gives us great flexibility in experimenting
with various governance models, knowing that we can always press the "reset" button
without fear of fragmentation or deadlock. See the US congress for a counter-example.
BDFL daily routine:
* Is the project governance stuck in a deadlock or irreversibly fragmented?
* If yes: refactor the project governance
* Are there issues or conflicts escalated by core?
* If yes: resolve them
* Go back to polishing that crown.
"""
[Rules.decisions]
title = "How are decisions made?"
text = """
Short answer: EVERYTHING IS A PULL REQUEST.
Docker 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 Docker, big and small, follow the same 3 steps:
* Step 1: Open a pull request. Anyone can do this.
* Step 2: Discuss the pull request. Anyone can do this.
* Step 3: Merge or refuse the pull request. Who does this depends on the nature
of the pull request and which areas of the project it affects. See *review flow*
for details.
Because Docker is such a large and active project, it's important for everyone to know
who is responsible for deciding what. That is determined by a precise set of rules.
* For every *decision* in the project, the rules should designate, in a deterministic way,
who should *decide*.
* For every *problem* in the project, the rules should designate, in a deterministic way,
who should be responsible for *fixing* it.
* For every *question* in the project, the rules should designate, in a deterministic way,
who should be expected to have the *answer*.
"""
[Rules.review]
title = "Review flow"
text = """
Pull requests should be processed according to the following flow:
* For each subsystem affected by the change, the maintainers of the subsystem must approve or refuse it.
It is the responsibility of the subsystem maintainers to process patches affecting them in a timely
manner.
* If the change affects areas of the code which are not part of a subsystem,
or if subsystem maintainers are unable to reach a timely decision, it must be approved by
the core maintainers.
* If the change affects the UI or public APIs, or if it represents a major change in architecture,
the architects must approve or refuse it.
* If the change affects the operations of the project, it must be approved or rejected by
the relevant operators.
* If the change affects the governance, philosophy, goals or principles of the project,
it must be approved by BDFL.
"""
[Rules.DCO]
title = "Helping contributors with the DCO"
text = """
The [DCO or `Sign your work`](
https://github.com/docker/docker/blob/master/CONTRIBUTING.md#sign-your-work)
requirement is not intended as a roadblock or speed bump.
Some Docker contributors are not as familiar with `git`, or have used a web based
editor, and thus asking them to `git commit --amend -s` is not the best way forward.
In this case, maintainers can update the commits based on clause (c) of the DCO. The
most trivial way for a contributor to allow the maintainer to do this, is to add
a DCO signature in a Pull Requests's comment, or a maintainer can simply note that
the change is sufficiently trivial that it does not substantially change the existing
contribution - i.e., a spelling change.
When you add someone's DCO, please also add your own to keep a log.

[Org.Subsystems]
# As the project grows, it gets separated into well-defined subsystems. Each subsystem
# has a dedicated group of maintainers, which are dedicated to that subsytem and responsible
# for its quality.
# This "cellular division" is the primary mechanism for scaling maintenance of the project as it grows.
#
# The maintainers of each subsytem are responsible for:
#
# 1. Exposing a clear road map for improving their subsystem.
# 2. Deliver prompt feedback and decisions on pull requests affecting their subsystem.
# 3. Be available to anyone with questions, bug reports, criticism etc.
# on their component. This includes IRC, GitHub requests and the mailing
# list.
# 4. Make sure their subsystem respects the philosophy, design and
# road map of the project.
#
# #### How to review patches to your subsystem
#
# Accepting pull requests:
#
# - If the pull request appears to be ready to merge, give it a `LGTM`, which
# stands for "Looks Good To Me".
# - If the pull request has some small problems that need to be changed, make
# a comment adressing the issues.
# - If the changes needed to a PR are small, you can add a "LGTM once the
# following comments are addressed..." this will reduce needless back and
# forth.
# - If the PR only needs a few changes before being merged, any MAINTAINER can
# make a replacement PR that incorporates the existing commits and fixes the
# problems before a fast track merge.
#
# Closing pull requests:
#
# - If a PR appears to be abandoned, after having attempted to contact the
# original contributor, then a replacement PR may be made. Once the
# replacement PR is made, any contributor may close the original one.
# - If you are not sure if the pull request implements a good feature or you
# do not understand the purpose of the PR, ask the contributor to provide
# more documentation. If the contributor is not able to adequately explain
# the purpose of the PR, the PR may be closed by any MAINTAINER.
# - If a MAINTAINER feels that the pull request is sufficiently architecturally
# flawed, or if the pull request needs significantly more design discussion
# before being considered, the MAINTAINER should close the pull request with
# a short explanation of what discussion still needs to be had. It is
# important not to leave such pull requests open, as this will waste both the
# MAINTAINER's time and the contributor's time. It is not good to string a
# contributor on for weeks or months, having them make many changes to a PR
# that will eventually be rejected.

Docker: the container engine [![Release](https://img.shields.io/github/release/docker/docker.svg)](https://github.com/docker/docker/releases/latest)
============================
Docker: the Linux container runtime
===================================
Docker is an open source project to pack, ship and run any application
as a lightweight container.
Docker complements LXC with a high-level API which operates at the process level. It runs unix processes with strong guarantees of isolation and repeatability across servers.
Docker containers are both *hardware-agnostic* and *platform-agnostic*.
This means they can run anywhere, from your laptop to the largest
cloud compute instance and everything in between - and they don't require
you to use a particular language, framework or packaging system. That
makes them great building blocks for deploying and scaling web apps,
databases, and backend services without depending on a particular stack
or provider.
Docker is a great building block for automating distributed systems: large-scale web deployments, database clusters, continuous deployment systems, private PaaS, service-oriented architectures, etc.
Docker began as an open-source implementation of the deployment engine which
powers [dotCloud](https://www.dotcloud.com), a popular Platform-as-a-Service.
It benefits directly from the experience accumulated over several years
of large-scale operation and support of hundreds of thousands of
applications and databases.
![Docker L](docs/sources/static_files/lego_docker.jpg "Docker")
![Docker L](docs/static_files/docker-logo-compressed.png "Docker")
* *Heterogeneous payloads*: any combination of binaries, libraries, configuration files, scripts, virtualenvs, jars, gems, tarballs, you name it. No more juggling between domain-specific tools. Docker can deploy and run them all.
## Security Disclosure
* *Any server*: docker can run on any x64 machine with a modern linux kernel - whether it's a laptop, a bare metal server or a VM. This makes it perfect for multi-cloud deployments.
Security is very important to us. If you have any issue regarding security,
please disclose the information responsibly by sending an email to
security@docker.com and not by creating a github issue.
* *Isolation*: docker isolates processes from each other and from the underlying host, using lightweight containers.
## Better than VMs
A common method for distributing applications and sandboxing their
execution is to use virtual machines, or VMs. Typical VM formats are
VMware's vmdk, Oracle VirtualBox's vdi, and Amazon EC2's ami. In theory
these formats should allow every developer to automatically package
their application into a "machine" for easy distribution and deployment.
In practice, that almost never happens, for a few reasons:
* *Size*: VMs are very large which makes them impractical to store
and transfer.
* *Performance*: running VMs consumes significant CPU and memory,
which makes them impractical in many scenarios, for example local
development of multi-tier applications, and large-scale deployment
of cpu and memory-intensive applications on large numbers of
machines.
* *Portability*: competing VM environments don't play well with each
other. Although conversion tools do exist, they are limited and
add even more overhead.
* *Hardware-centric*: VMs were designed with machine operators in
mind, not software developers. As a result, they offer very
limited tooling for what developers need most: building, testing
and running their software. For example, VMs offer no facilities
for application versioning, monitoring, configuration, logging or
service discovery.
By contrast, Docker relies on a different sandboxing method known as
*containerization*. Unlike traditional virtualization, containerization
takes place at the kernel level. Most modern operating system kernels
now support the primitives necessary for containerization, including
Linux with [openvz](https://openvz.org),
[vserver](http://linux-vserver.org) and more recently
[lxc](https://linuxcontainers.org/), Solaris with
[zones](https://docs.oracle.com/cd/E26502_01/html/E29024/preface-1.html#scrolltoc),
and FreeBSD with
[Jails](https://www.freebsd.org/doc/handbook/jails.html).
Docker builds on top of these low-level primitives to offer developers a
portable format and runtime environment that solves all four problems.
Docker containers are small (and their transfer can be optimized with
layers), they have basically zero memory and cpu overhead, they are
completely portable, and are designed from the ground up with an
application-centric design.
Perhaps best of all, because Docker operates at the OS level, it can still be
run inside a VM!
## Plays well with others
Docker does not require you to buy into a particular programming
language, framework, packaging system, or configuration language.
Is your application a Unix process? Does it use files, tcp connections,
environment variables, standard Unix streams and command-line arguments
as inputs and outputs? Then Docker can run it.
Can your application's build be expressed as a sequence of such
commands? Then Docker can build it.
## Escape dependency hell
A common problem for developers is the difficulty of managing all
their application's dependencies in a simple and automated way.
This is usually difficult for several reasons:
* *Cross-platform dependencies*. Modern applications often depend on
a combination of system libraries and binaries, language-specific
packages, framework-specific modules, internal components
developed for another project, etc. These dependencies live in
different "worlds" and require different tools - these tools
typically don't work well with each other, requiring awkward
custom integrations.
* *Conflicting dependencies*. Different applications may depend on
different versions of the same dependency. Packaging tools handle
these situations with various degrees of ease - but they all
handle them in different and incompatible ways, which again forces
the developer to do extra work.
* *Custom dependencies*. A developer may need to prepare a custom
version of their application's dependency. Some packaging systems
can handle custom versions of a dependency, others can't - and all
of them handle it differently.
* *Repeatability*: because containers are isolated in their own filesystem, they behave the same regardless of where, when, and alongside what they run.
Docker solves the problem of dependency hell by giving the developer a simple
way to express *all* their application's dependencies in one place, while
streamlining the process of assembling them. If this makes you think of
[XKCD 927](https://xkcd.com/927/), don't worry. Docker doesn't
*replace* your favorite packaging systems. It simply orchestrates
their use in a simple and repeatable way. How does it do that? With
layers.
Notable features
-----------------
Docker defines a build as running a sequence of Unix commands, one
after the other, in the same container. Build commands modify the
contents of the container (usually by installing new files on the
filesystem), the next command modifies it some more, etc. Since each
build command inherits the result of the previous commands, the
*order* in which the commands are executed expresses *dependencies*.
* Filesystem isolation: each process container runs in a completely separate root filesystem.
Here's a typical Docker build process:
* Resource isolation: system resources like cpu and memory can be allocated differently to each process container, using cgroups.
* Network isolation: each process container runs in its own network namespace, with a virtual interface and IP address of its own.
* Copy-on-write: root filesystems are created using copy-on-write, which makes deployment extremely fast, memory-cheap and disk-cheap.
* Logging: the standard streams (stdout/stderr/stdin) of each process container are collected and logged for real-time or batch retrieval.
* Change management: changes to a container's filesystem can be committed into a new image and re-used to create more containers. No templating or manual configuration required.
* Interactive shell: docker can allocate a pseudo-tty and attach to the standard input of any container, for example to run a throwaway interactive shell.
Install instructions
==================
Quick install on Ubuntu 12.04 and 12.10
---------------------------------------
```bash
FROM ubuntu:12.04
RUN apt-get update && apt-get install -y python python-pip curl
RUN curl -sSL https://github.com/shykes/helloflask/archive/master.tar.gz | tar -xzv
RUN cd helloflask-master && pip install -r requirements.txt
curl get.docker.io | sh -x
```
Note that Docker doesn't care *how* dependencies are built - as long
as they can be built by running a Unix command in a container.
Binary installs
----------------
Docker supports the following binary installation methods.
Note that some methods are community contributions and not yet officially supported.
Getting started
===============
* [Ubuntu 12.04 and 12.10 (officially supported)](http://docs.docker.io/en/latest/installation/ubuntulinux/)
* [Arch Linux](http://docs.docker.io/en/latest/installation/archlinux/)
* [MacOS X (with Vagrant)](http://docs.docker.io/en/latest/installation/macos/)
* [Windows (with Vagrant)](http://docs.docker.io/en/latest/installation/windows/)
* [Amazon EC2 (with Vagrant)](http://docs.docker.io/en/latest/installation/amazon/)
Docker can be installed on your local machine as well as servers - both
bare metal and virtualized. It is available as a binary on most modern
Linux systems, or as a VM on Windows, Mac and other systems.
Installing from source
----------------------
We also offer an [interactive tutorial](https://www.docker.com/tryit/)
for quickly learning the basics of using Docker.
1. Make sure you have a [Go language](http://golang.org/doc/install) compiler and [git](http://git-scm.com) installed.
For up-to-date install instructions, see the [Docs](https://docs.docker.com).
2. Checkout the source code
```bash
git clone http://github.com/dotcloud/docker
```
3. Build the docker binary
```bash
cd docker
make VERBOSE=1
sudo cp ./bin/docker /usr/local/bin/docker
```
Usage examples
==============
Docker can be used to run short-lived commands, long-running daemons
(app servers, databases, etc.), interactive shell sessions, etc.
First run the docker daemon
---------------------------
You can find a [list of real-world
examples](https://docs.docker.com/examples/) in the
documentation.
All the examples assume your machine is running the docker daemon. To run the docker daemon in the background, simply type:
```bash
# On a production system you want this running in an init script
sudo docker -d &
```
Now you can run docker in client mode: all commands will be forwarded to the docker daemon, so the client can run from any account.
```bash
# Now you can run docker commands from any account.
docker help
```
Throwaway shell in a base ubuntu image
--------------------------------------
```bash
docker pull ubuntu:12.10
# Run an interactive shell, allocate a tty, attach stdin and stdout
# To detach the tty without exiting the shell, use the escape sequence Ctrl-p + Ctrl-q
docker run -i -t ubuntu:12.10 /bin/bash
```
Starting a long-running worker process
--------------------------------------
```bash
# Start a very useful long-running process
JOB=$(docker run -d ubuntu /bin/sh -c "while true; do echo Hello world; sleep 1; done")
# Collect the output of the job so far
docker logs $JOB
# Kill the job
docker kill $JOB
```
Running an irc bouncer
----------------------
```bash
BOUNCER_ID=$(docker run -d -p 6667 -u irc shykes/znc $USER $PASSWORD)
echo "Configure your irc client to connect to port $(docker port $BOUNCER_ID 6667) of this machine"
```
Running Redis
-------------
```bash
REDIS_ID=$(docker run -d -p 6379 shykes/redis redis-server)
echo "Configure your redis client to connect to port $(docker port $REDIS_ID 6379) of this machine"
```
Share your own image!
---------------------
```bash
CONTAINER=$(docker run -d ubuntu:12.10 apt-get install -y curl)
docker commit -m "Installed curl" $CONTAINER $USER/betterbase
docker push $USER/betterbase
```
A list of publicly available images is [available here](https://github.com/dotcloud/docker/wiki/Public-docker-images).
Expose a service on a TCP port
------------------------------
```bash
# Expose port 4444 of this container, and tell netcat to listen on it
JOB=$(docker run -d -p 4444 base /bin/nc -l -p 4444)
# Which public port is NATed to my container?
PORT=$(docker port $JOB 4444)
# Connect to the public port via the host's public address
# Please note that because of how routing works connecting to localhost or 127.0.0.1 $PORT will not work.
IP=$(ifconfig eth0 | perl -n -e 'if (m/inet addr:([\d\.]+)/g) { print $1 }')
echo hello world | nc $IP $PORT
# Verify that the network connection worked
echo "Daemon received: $(docker logs $JOB)"
```

What is a Standard Container?
=============================
There are a number of projects under development that are based on Docker's
core technology. These projects expand the tooling built around the
Docker platform to broaden its application and utility.
* [Docker Registry](https://github.com/docker/distribution): Registry
server for Docker (hosting/delivery of repositories and images)
* [Docker Machine](https://github.com/docker/machine): Machine management
for a container-centric world
* [Docker Swarm](https://github.com/docker/swarm): A Docker-native clustering
system
* [Docker Compose](https://github.com/docker/compose) (formerly Fig):
Define and run multi-container apps
* [Kitematic](https://github.com/kitematic/kitematic): The easiest way to use
Docker on Mac and Windows
Docker defines a unit of software delivery called a Standard Container. The goal of a Standard Container is to encapsulate a software component and all its dependencies in
a format that is self-describing and portable, so that any compliant runtime can run it without extra dependencies, regardless of the underlying machine and the contents of the container.
The spec for Standard Containers is currently a work in progress, but it is very straightforward. It mostly defines 1) an image format, 2) a set of standard operations, and 3) an execution environment.
A great analogy for this is the shipping container. Just like Standard Containers are a fundamental unit of software delivery, shipping containers (http://bricks.argz.com/ins/7823-1/12) are a fundamental unit of physical delivery.
### 1. STANDARD OPERATIONS
Just like shipping containers, Standard Containers define a set of STANDARD OPERATIONS. Shipping containers can be lifted, stacked, locked, loaded, unloaded and labelled. Similarly, standard containers can be started, stopped, copied, snapshotted, downloaded, uploaded and tagged.
### 2. CONTENT-AGNOSTIC
Just like shipping containers, Standard Containers are CONTENT-AGNOSTIC: all standard operations have the same effect regardless of the contents. A shipping container will be stacked in exactly the same way whether it contains Vietnamese powder coffee or spare Maserati parts. Similarly, Standard Containers are started or uploaded in the same way whether they contain a postgres database, a php application with its dependencies and application server, or Java build artifacts.
### 3. INFRASTRUCTURE-AGNOSTIC
Both types of containers are INFRASTRUCTURE-AGNOSTIC: they can be transported to thousands of facilities around the world, and manipulated by a wide variety of equipment. A shipping container can be packed in a factory in Ukraine, transported by truck to the nearest routing center, stacked onto a train, loaded into a German boat by an Australian-built crane, stored in a warehouse at a US facility, etc. Similarly, a standard container can be bundled on my laptop, uploaded to S3, downloaded, run and snapshotted by a build server at Equinix in Virginia, uploaded to 10 staging servers in a home-made Openstack cluster, then sent to 30 production instances across 3 EC2 regions.
### 4. DESIGNED FOR AUTOMATION
Because they offer the same standard operations regardless of content and infrastructure, Standard Containers, just like their physical counterpart, are extremely well-suited for automation. In fact, you could say automation is their secret weapon.
Many things that once required time-consuming and error-prone human effort can now be programmed. Before shipping containers, a bag of powder coffee was hauled, dragged, dropped, rolled and stacked by 10 different people in 10 different locations by the time it reached its destination. 1 out of 50 disappeared. 1 out of 20 was damaged. The process was slow, inefficient and cost a fortune - and was entirely different depending on the facility and the type of goods.
Similarly, before Standard Containers, by the time a software component ran in production, it had been individually built, configured, bundled, documented, patched, vendored, templated, tweaked and instrumented by 10 different people on 10 different computers. Builds failed, libraries conflicted, mirrors crashed, post-it notes were lost, logs were misplaced, cluster updates were half-broken. The process was slow, inefficient and cost a fortune - and was entirely different depending on the language and infrastructure provider.
### 5. INDUSTRIAL-GRADE DELIVERY
There are 17 million shipping containers in existence, packed with every physical good imaginable. Every single one of them can be loaded on the same boats, by the same cranes, in the same facilities, and sent anywhere in the World with incredible efficiency. It is embarrassing to think that a 30 ton shipment of coffee can safely travel half-way across the World in *less time* than it takes a software team to deliver its code from one datacenter to another sitting 10 miles away.
With Standard Containers we can put an end to that embarrassment, by making INDUSTRIAL-GRADE DELIVERY of software a reality.

Docker Engine Roadmap
=====================
### How should I use this document?
This document provides description of items that the project decided to prioritize. This should
serve as a reference point for Docker contributors to understand where the project is going, and
help determine if a contribution could be conflicting with some longer terms plans.
The fact that a feature isn't listed here doesn't mean that a patch for it will automatically be
refused (except for those mentioned as "frozen features" below)! We are always happy to receive
patches for new cool features we haven't thought about, or didn't judge priority. Please however
understand that such patches might take longer for us to review.
### How can I help?
Short term objectives are listed in the [wiki](https://github.com/docker/docker/wiki) and described
in [Issues](https://github.com/docker/docker/issues?q=is%3Aopen+is%3Aissue+label%3Aroadmap). Our
goal is to split down the workload in such way that anybody can jump in and help. Please comment on
issues if you want to take it to avoid duplicating effort! Similarly, if a maintainer is already
assigned on an issue you'd like to participate in, pinging him on IRC or GitHub to offer your help is
the best way to go.
### How can I add something to the roadmap?
The roadmap process is new to the Docker Engine: we are only beginning to structure and document the
project objectives. Our immediate goal is to be more transparent, and work with our community to
focus our efforts on fewer prioritized topics.
We hope to offer in the near future a process allowing anyone to propose a topic to the roadmap, but
we are not quite there yet. For the time being, the BDFL remains the keeper of the roadmap, and we
won't be accepting pull requests adding or removing items from this file.
# 1. Features and refactoring
## 1.1 Security
Security is a top objective for the Docker Engine. The most notable items we intend to provide in
the near future are:
- Trusted distribution of images: the effort is driven by the [distribution](https://github.com/docker/distribution)
group but will have significant impact on the Engine
- [User namespaces](https://github.com/docker/docker/pull/12648)
- [Seccomp support](https://github.com/docker/libcontainer/pull/613)
## 1.2 Plumbing project
We define a plumbing tool as a standalone piece of software usable and meaningful on its own. In
the current state of the Docker Engine, most subsystems provide independent functionalities (such
the builder, pushing and pulling images, running applications in a containerized environment, etc)
but all are coupled in a single binary. We want to offer the users to flexibility to use only the
pieces they need, and we will also gain in maintainability by splitting the project among multiple
repositories.
As it currently stands, the rough design outlines is to have:
- Low level plumbing tools, each dealing with one responsibility (e.g., [runC](https://runc.io))
- Docker subsystems services, each exposing an elementary concept over an API, and relying on one or
multiple lower level plumbing tools for their implementation (e.g., network management)
- Docker Engine to expose higher level actions (e.g., create a container with volume `V` and network
`N`), while still providing pass-through access to the individual subsystems.
The architectural details are still being worked on, but one thing we know for sure is that we need
to technically decouple the pieces.
### 1.2.1 Runtime
A Runtime tool already exists today in the form of [runC](https://github.com/opencontainers/runc).
We intend to modify the Engine to directly call out to a binary implementing the Open Containers
Specification such as runC rather than relying on libcontainer to set the container runtime up.
This plan will deprecate the existing [`execdriver`](https://github.com/docker/docker/tree/master/daemon/execdriver)
as different runtime backends will be implemented as separated binaries instead of being compiled
into the Engine.
### 1.2.2 Builder
The Builder (i.e., the ability to build an image from a Dockerfile) is already nicely decoupled,
but would benefit from being entirely separated from the Engine, and rely on the standard Engine
API for its operations.
### 1.2.3 Distribution
Distribution already has a [dedicated repository](https://github.com/docker/distribution) which
holds the implementation for Registry v2 and client libraries. We could imagine going further by
having the Engine call out to a binary providing image distribution related functionalities.
There are two short term goals related to image distribution. The first is stabilize and simplify
the push/pull code. Following that is the conversion to the more secure Registry V2 protocol.
### 1.2.4 Networking
Most of networking related code was already decoupled today in [libnetwork](https://github.com/docker/libnetwork).
As with other ingredients, we might want to take it a step further and make it a meaningful utility
that the Engine would call out to instead of a library.
## 1.3 Plugins
An initiative around plugins started with Docker 1.7.0, with the goal of allowing for out of
process extensibility of some Docker functionalities, starting with volumes and networking. The
approach is to provide specific extension points rather than generic hooking facilities. We also
deliberately keep the extensions API the simplest possible, expanding as we discover valid use
cases that cannot be implemented.
At the time of writing:
- Plugin support is merged as an experimental feature: real world use cases and user feedback will
help us refine the UX to make the feature more user friendly.
- There are no immediate plans to expand on the number of pluggable subsystems.
- Golang 1.5 might add language support for [plugins](https://docs.google.com/document/d/1nr-TQHw_er6GOQRsF6T43GGhFDelrAP0NqSS_00RgZQ)
which we consider supporting as an alternative to JSON/HTTP.
## 1.4 Volume management
Volumes are not a first class citizen in the Engine today: we would like better volume management,
similar to the way network are managed in the new [CNM](https://github.com/docker/docker/issues/9983).
## 1.5 Better API implementation
The current Engine API is insufficiently typed, versioned, and ultimately hard to maintain. We
also suffer from the lack of a common implementation with [Swarm](https://github.com/docker/swarm).
## 1.6 Checkpoint/restore
Support for checkpoint/restore was [merged](https://github.com/docker/libcontainer/pull/479) in
[libcontainer](https://github.com/docker/libcontainer) and made available through [runC](https://runc.io):
we intend to take advantage of it in the Engine.
# 2 Frozen features
## 2.1 Docker exec
We won't accept patches expanding the surface of `docker exec`, which we intend to keep as a
*debugging* feature, as well as being strongly dependent on the Runtime ingredient effort.
## 2.2 Dockerfile syntax
The Dockerfile syntax as we know it is simple, and has proven successful in supporting all our
[official images](https://github.com/docker-library/official-images). Although this is *not* a
definitive move, we temporarily won't accept more patches to the Dockerfile syntax for several
reasons:
- Long term impact of syntax changes is a sensitive matter that require an amount of attention
the volume of Engine codebase and activity today doesn't allow us to provide.
- Allowing the Builder to be implemented as a separate utility consuming the Engine's API will
open the door for many possibilities, such as offering alternate syntaxes or DSL for existing
languages without cluttering the Engine's codebase.
- A standalone Builder will also offer the opportunity for a better dedicated group of maintainers
to own the Dockerfile syntax and decide collectively on the direction to give it.
- Our experience with official images tend to show that no new instruction or syntax expansion is
*strictly* necessary for the majority of use cases, and although we are aware many things are still
lacking for many, we cannot make it a priority yet for the above reasons.
Again, this is not about saying that the Dockerfile syntax is done, it's about making choices about
what we want to do first!
## 2.3 Remote Registry Operations
A large amount of work is ongoing in the area of image distribution and
provenance. This includes moving to the V2 Registry API and heavily
refactoring the code that powers these features. The desired result is more
secure, reliable and easier to use image distribution.
Part of the problem with this part of the code base is the lack of a stable
and flexible interface. If new features are added that access the registry
without solidifying these interfaces, achieving feature parity will continue
to be elusive. While we get a handle on this situation, we are imposing a
moratorium on new code that accesses the Registry API in commands that don't
already make remote calls.
Currently, only the following commands cause interaction with a remote
registry:
- push
- pull
- run
- build
- search
- login
In the interest of stabilizing the registry access model during this ongoing
work, we are not accepting additions to other commands that will cause remote
interaction with the Registry API. This moratorium will lift when the goals of
the distribution project have been met.

## Spec for data volumes
Spec owner: Solomon Hykes <solomon@dotcloud.com>
Data volumes (issue #111) are a much-requested feature which trigger much discussion and debate. Below is the current authoritative spec for implementing data volumes.
This spec will be deprecated once the feature is fully implemented.
Discussion, requests, trolls, demands, offerings, threats and other forms of supplications concerning this spec should be addressed to Solomon here: https://github.com/dotcloud/docker/issues/111
### 1. Creating data volumes
At container creation, parts of a container's filesystem can be mounted as separate data volumes. Volumes are defined with the -v flag.
For example:
```bash
$ docker run -v /var/lib/postgres -v /var/log postgres /usr/bin/postgres
```
In this example, a new container is created from the 'postgres' image. At the same time, docker creates 2 new data volumes: one will be mapped to the container at /var/lib/postgres, the other at /var/log.
2 important notes:
1) Volumes don't have top-level names. At no point does the user provide a name, or is a name given to him. Volumes are identified by the path at which they are mounted inside their container.
2) The user doesn't choose the source of the volume. Docker only mounts volumes it created itself, in the same way that it only runs containers that it created itself. That is by design.
### 2. Sharing data volumes
Instead of creating its own volumes, a container can share another container's volumes. For example:
```bash
$ docker run --volumes-from $OTHER_CONTAINER_ID postgres /usr/local/bin/postgres-backup
```
In this example, a new container is created from the 'postgres' example. At the same time, docker will *re-use* the 2 data volumes created in the previous example. One volume will be mounted on the /var/lib/postgres of *both* containers, and the other will be mounted on the /var/log of both containers.
### 3. Under the hood
Docker stores volumes in /var/lib/docker/volumes. Each volume receives a globally unique ID at creation, and is stored at /var/lib/docker/volumes/ID.
At creation, volumes are attached to a single container - the source of truth for this mapping will be the container's configuration.
Mounting a volume consists of calling "mount --bind" from the volume's directory to the appropriate sub-directory of the container mountpoint. This may be done by Docker itself, or farmed out to lxc (which supports mount-binding) if possible.
### 4. Backups, transfers and other volume operations
Volumes sometimes need to be backed up, transfered between hosts, synchronized, etc. These operations typically are application-specific or site-specific, eg. rsync vs. S3 upload vs. replication vs...
Rather than attempting to implement all these scenarios directly, Docker will allow for custom implementations using an extension mechanism.
### 5. Custom volume handlers
Docker allows for arbitrary code to be executed against a container's volumes, to implement any custom action: backup, transfer, synchronization across hosts, etc.
Here's an example:
```bash
$ DB=$(docker run -d -v /var/lib/postgres -v /var/log postgres /usr/bin/postgres)
$ BACKUP_JOB=$(docker run -d --volumes-from $DB shykes/backuper /usr/local/bin/backup-postgres --s3creds=$S3CREDS)
$ docker wait $BACKUP_JOB
```
Congratulations, you just implemented a custom volume handler, using Docker's built-in ability to 1) execute arbitrary code and 2) share volumes between containers.

## Legacy API type versions
This package includes types for legacy API versions. The stable version of the API types live in `api/types/*.go`.
Consider moving a type here when you need to keep backwards compatibility in the API. This legacy types are organized by the latest API version they appear in. For instance, types in the `v1p19` package are valid for API versions below or equal `1.19`. Types in the `v1p20` package are valid for the API version `1.20`, since the versions below that will use the legacy types in `v1p19`.
### Package name conventions
The package name convention is to use `v` as a prefix for the version number and `p`(patch) as a separator. We use this nomenclature due to a few restrictions in the Go package name convention:
1. We cannot use `.` because it's interpreted by the language, think of `v1.20.CallFunction`.
2. We cannot use `_` because golint complains abount it. The code is actually valid, but it looks probably more weird: `v1_20.CallFunction`.
For instance, if you want to modify a type that was available in the version `1.21` of the API but it will have different fields in the version `1.22`, you want to create a new package under `api/types/versions/v1p21`.
