## Contribution Guidelines
|
||||||
|
|
||||||
|
### Pull requests are always welcome
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
We're trying very hard to keep runc 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* runc.
|
||||||
|
|
||||||
|
|
||||||
|
### Conventions
|
||||||
|
|
||||||
|
Fork the repo and make changes on your fork in a feature branch:
|
||||||
|
|
||||||
|
- 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 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 ``docs/README.md`` for more
|
||||||
|
information on building the docs and how docs get released.
|
||||||
|
|
||||||
|
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 plugins that do this automatically.
|
||||||
|
|
||||||
|
Pull requests descriptions should be as clear as possible and include a
|
||||||
|
reference to all the issues that they address.
|
||||||
|
|
||||||
|
Pull requests must not contain commits from other users or branches.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
Code review comments may be added to your pull request. Discuss, then make the
|
||||||
|
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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||

# The libcontainer Contributors' Guide
|
|
||||||
|
|
||||||
Want to hack on libcontainer? Awesome! Here are instructions to get you
|
|
||||||
started. They are probably not perfect, please let us know if anything
|
|
||||||
feels wrong or incomplete.
|
|
||||||
|
|
||||||
## Reporting Issues
|
|
||||||
|
|
||||||
When reporting [issues](https://github.com/opencontainers/runc/libcontainer/issues)
|
|
||||||
on GitHub please include your host OS (Ubuntu 12.04, Fedora 19, etc),
|
|
||||||
the output of `uname -a`. Please include the steps required to reproduce
|
|
||||||
the problem if possible and applicable.
|
|
||||||
This information will help us review and fix your issue faster.
|
|
||||||
|
|
||||||
## Development Environment
|
|
||||||
|
|
||||||
### Requirements
|
|
||||||
|
|
||||||
For best results, use a Linux development environment.
|
|
||||||
The following packages are required to compile libcontainer natively.
|
|
||||||
|
|
||||||
- Golang 1.3
|
|
||||||
- GCC
|
|
||||||
- git
|
|
||||||
- cgutils
|
|
||||||
|
|
||||||
You can develop on OSX, but you are limited to Dockerfile-based builds only.
|
|
||||||
|
|
||||||
### Building libcontainer from Dockerfile
|
|
||||||
|
|
||||||
make all
|
|
||||||
|
|
||||||
This is the easiest way of building libcontainer.
|
|
||||||
As this build is done using Docker, you can even run this from [OSX](https://github.com/boot2docker/boot2docker)
|
|
||||||
|
|
||||||
### Testing changes with "nsinit"
|
|
||||||
|
|
||||||
make sh
|
|
||||||
|
|
||||||
This will create an container that runs `nsinit exec sh` on a busybox rootfs with the configuration from ['minimal.json'](https://github.com/opencontainers/runc/libcontainer/blob/master/sample_configs/minimal.json).
|
|
||||||
Like the previous command, you can run this on OSX too!
|
|
||||||
|
|
||||||
### Building libcontainer directly
|
|
||||||
|
|
||||||
> Note: You should add the `vendor` directory to your GOPATH to use the vendored libraries
|
|
||||||
|
|
||||||
./update-vendor.sh
|
|
||||||
go get -d ./...
|
|
||||||
make direct-build
|
|
||||||
# Run the tests
|
|
||||||
make direct-test-short | egrep --color 'FAIL|$'
|
|
||||||
# Run all the test
|
|
||||||
make direct-test | egrep --color 'FAIL|$'
|
|
||||||
|
|
||||||
### Testing Changes with "nsinit" directly
|
|
||||||
|
|
||||||
To test a change:
|
|
||||||
|
|
||||||
# Install nsinit
|
|
||||||
make direct-install
|
|
||||||
|
|
||||||
# Optional, add a docker0 bridge
|
|
||||||
ip link add docker0 type bridge
|
|
||||||
ifconfig docker0 172.17.0.1/16 up
|
|
||||||
|
|
||||||
mkdir testfs
|
|
||||||
curl -sSL https://github.com/jpetazzo/docker-busybox/raw/buildroot-2014.02/rootfs.tar | tar -xC testfs
|
|
||||||
cd testfs
|
|
||||||
cp <your-sample-config.json> container.json
|
|
||||||
nsinit exec sh
|
|
||||||
|
|
||||||
## Contribution Guidelines
|
|
||||||
|
|
||||||
### Pull requests are always welcome

|
||||||

|
|
||||||

|

|
|
||||||
|
|
||||||
### Discuss your design on the mailing list
|
|
||||||
|
|
||||||
We recommend discussing your plans [on the mailing
|
|
||||||
list](https://groups.google.com/forum/?fromgroups#!forum/libcontainer)
|
|
||||||
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...
|
|
||||||
|
|
||||||
Any significant improvement should be documented as [a GitHub
|
|
||||||
issue](https://github.com/opencontainers/runc/libcontainer/issues) before anybody
|
|
||||||
starts working on it.
|
|
||||||
|
|
||||||
### ...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 repo and make changes on your fork in a feature branch:
|
|
||||||
|
|
||||||
- If it's a bugfix branch, name it XXX-something where XXX is the number of the

|
|

|
|
||||||
chars) written in the imperative, followed by an optional, more detailed
|
|
||||||

|
|

or `Fixes #XXX`, which will automatically close the issue when merged.
|
|
||||||
|
|
||||||
### Testing
|
|
||||||
|
|
||||||
Make sure you include suitable tests, preferably unit tests, in your pull request
|
|
||||||
and that all the tests pass.
|
|
||||||
|
|
||||||
*Instructions for running tests to be added.*
|
|
||||||
|
|
||||||
### Merge approval
|
|
||||||
|
|
||||||
libcontainer maintainers use LGTM (looks good to me) in comments on the code review
|
|
||||||
to indicate acceptance.
|
|
||||||
|
|
||||||
A change requires LGTMs from at lease two maintainers. One of those must come from
|
|
||||||
a maintainer of the component affected. For example, if a change affects `netlink/`
|
|
||||||
and `security`, it needs at least one LGTM from a maintainer of each. Maintainers
|
|
||||||
only need one LGTM as presumably they LGTM their own change.
|
|
||||||
|

||||||

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:
|
|
||||||
|
|
||||||
Docker-DCO-1.1-Signed-off-by: Joe Smith <joe.smith@email.com> (github: github_handle)
|
|
||||||
|
|
||||||
using your real name (sorry, no pseudonyms or anonymous contributions.)
|
|
||||||
|
|
||||||
One way to automate this, is customise your get ``commit.template`` by adding
|
|
||||||
a ``prepare-commit-msg`` hook to your libcontainer checkout:
|
|
||||||
|
|
||||||
```
|
|
||||||
curl -o .git/hooks/prepare-commit-msg https://raw.githubusercontent.com/docker/docker/master/contrib/prepare-commit-msg.hook && chmod +x .git/hooks/prepare-commit-msg
|
|
||||||
```
|
|
||||||
|
|
||||||
* Note: the above script expects to find your GitHub user name in ``git config --get github.user``
|
|
||||||
|
|
||||||
#### Small patch exception
|
|
||||||
|
|
||||||
There are several exceptions to the signing requirement. Currently these are:
|
|
||||||
|
|
||||||
* Your patch fixes spelling or grammar errors.
|
|
||||||
* Your patch is a single line change to documentation contained in the
|
|
||||||
`docs` directory.
|
|
||||||
* Your patch fixes Markdown formatting or syntax errors in the
|
|
||||||
documentation contained in the `docs` directory.
|
|
||||||
|
|
||||||
If you have any questions, please refer to the FAQ in the [docs](to be written)
|
|
||||||
|
|
||||||
### How can I become a maintainer?
|
|
||||||
|
|
||||||
* Step 1: learn the component inside out
|
|
||||||
* Step 2: make yourself useful by contributing code, bugfixes, support etc.
|
|
||||||
* Step 3: volunteer on the irc channel (#libcontainer@freenode)
|
|
||||||
|
|
||||||
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!

||||||
(an example is provided in the Appendix below).
|
|
||||||
|
|
||||||
"Derivative Works" shall mean any work, whether in Source or Object
|
|
||||||
form, that is based on (or derived from) the Work and for which the
|
|
||||||
editorial revisions, annotations, elaborations, or other modifications
|
|
||||||
represent, as a whole, an original work of authorship. For the purposes
|
|
||||||
of this License, Derivative Works shall not include works that remain
|
|
||||||
separable from, or merely link (or bind by name) to the interfaces of,
|
|
||||||
the Work and Derivative Works thereof.
|
|
||||||
|
|
||||||
"Contribution" shall mean any work of authorship, including
|
|
||||||
the original version of the Work and any modifications or additions
|
|
||||||
to that Work or Derivative Works thereof, that is intentionally
|
|
||||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
|
||||||
or by an individual or Legal Entity authorized to submit on behalf of
|
|
||||||
the copyright owner. For the purposes of this definition, "submitted"

|
|
||||||
excluding communication that is conspicuously marked or otherwise
|
|
||||||

|
|
||||||
|
|
||||||
"Contributor" shall mean Licensor and any individual or Legal Entity

|
||||||

|
|
||||||
|
|
||||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
|
||||||
this License, each Contributor hereby grants to You a perpetual,
|
|
||||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|
||||||
copyright license to reproduce, prepare Derivative Works of,
|
|
||||||
publicly display, publicly perform, sublicense, and distribute the
|
|
||||||
Work and such Derivative Works in Source or Object form.
|
|
||||||
|
|
||||||
3. Grant of Patent License. Subject to the terms and conditions of
|
|
||||||
this License, each Contributor hereby grants to You a perpetual,
|
|
||||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|
||||||
(except as stated in this section) patent license to make, have made,
|
|
||||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
|
||||||
where such license applies only to those patent claims licensable
|
|
||||||
by such Contributor that are necessarily infringed by their
|
|
||||||
Contribution(s) alone or by combination of their Contribution(s)
|
|
||||||
with the Work to which such Contribution(s) was submitted. If You
|
|
||||||
institute patent litigation against any entity (including a
|
|
||||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
|
||||||
or a Contribution incorporated within the Work constitutes direct
|
|
||||||
or contributory patent infringement, then any patent licenses
|
|
||||||
granted to You under this License for that Work shall terminate
|
|
||||||
as of the date such litigation is filed.
|
|
||||||
|
|
||||||
4. Redistribution. You may reproduce and distribute copies of the
|
|
||||||
Work or Derivative Works thereof in any medium, with or without
|
|
||||||
modifications, and in Source or Object form, provided that You
|
|
||||||
meet the following conditions:
|
|
||||||
|
|
||||||
(a) You must give any other recipients of the Work or
|
|
||||||
Derivative Works a copy of this License; and
|
|
||||||
|
|
||||||
(b) You must cause any modified files to carry prominent notices
|
|
||||||
stating that You changed the files; and
|
|
||||||
|
|
||||||
(c) You must retain, in the Source form of any Derivative Works
|
|
||||||
that You distribute, all copyright, patent, trademark, and
|
|
||||||
attribution notices from the Source form of the Work,
|
|
||||||
excluding those notices that do not pertain to any part of
|
|
||||||
the Derivative Works; and
|
|
||||||
|
|
||||||
(d) If the Work includes a "NOTICE" text file as part of its
|
|
||||||
distribution, then any Derivative Works that You distribute must
|
|
||||||
include a readable copy of the attribution notices contained
|
|
||||||
within such NOTICE file, excluding those notices that do not
|
|
||||||
pertain to any part of the Derivative Works, in at least one
|
|
||||||
of the following places: within a NOTICE text file distributed
|
|
||||||
as part of the Derivative Works; within the Source form or
|
|
||||||
documentation, if provided along with the Derivative Works; or,
|
|
||||||
within a display generated by the Derivative Works, if and
|
|
||||||
wherever such third-party notices normally appear. The contents
|
|
||||||
of the NOTICE file are for informational purposes only and
|
|
||||||
do not modify the License. You may add Your own attribution
|
|
||||||
notices within Derivative Works that You distribute, alongside
|
|
||||||
or as an addendum to the NOTICE text from the Work, provided
|
|
||||||
that such additional attribution notices cannot be construed
|
|
||||||
as modifying the License.
|
|
||||||
|
|
||||||
You may add Your own copyright statement to Your modifications and
|
|
||||||
may provide additional or different license terms and conditions
|
|
||||||
for use, reproduction, or distribution of Your modifications, or
|
|
||||||
for any such Derivative Works as a whole, provided Your use,
|
|
||||||
reproduction, and distribution of the Work otherwise complies with
|
|
||||||
the conditions stated in this License.
|
|
||||||
|
|
||||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
|
||||||
any Contribution intentionally submitted for inclusion in the Work
|
|
||||||
by You to the Licensor shall be under the terms and conditions of
|
|
||||||
this License, without any additional terms or conditions.
|
|
||||||
Notwithstanding the above, nothing herein shall supersede or modify
|
|
||||||
the terms of any separate license agreement you may have executed
|
|
||||||
with Licensor regarding such Contributions.
|
|
||||||
|
|
||||||
6. Trademarks. This License does not grant permission to use the trade
|
|
||||||
names, trademarks, service marks, or product names of the Licensor,
|
|
||||||
except as required for reasonable and customary use in describing the
|
|
||||||
origin of the Work and reproducing the content of the NOTICE file.
|
|
||||||
|
|
||||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
|
||||||
agreed to in writing, Licensor provides the Work (and each
|
|
||||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
|
||||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
|
||||||
implied, including, without limitation, any warranties or conditions
|
|
||||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
|
||||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
|
||||||
appropriateness of using or redistributing the Work and assume any
|
|
||||||
risks associated with Your exercise of permissions under this License.
|
|
||||||
|
|
||||||
8. Limitation of Liability. In no event and under no legal theory,
|
|
||||||
whether in tort (including negligence), contract, or otherwise,
|
|
||||||
unless required by applicable law (such as deliberate and grossly
|
|
||||||
negligent acts) or agreed to in writing, shall any Contributor be
|
|
||||||
liable to You for damages, including any direct, indirect, special,
|
|
||||||
incidental, or consequential damages of any character arising as a
|
|
||||||
result of this License or out of the use or inability to use the
|
|
||||||
Work (including but not limited to damages for loss of goodwill,
|
|
||||||
work stoppage, computer failure or malfunction, or any and all
|
|
||||||
other commercial damages or losses), even if such Contributor
|
|
||||||
has been advised of the possibility of such damages.
|
|
||||||
|
|
||||||
9. Accepting Warranty or Additional Liability. While redistributing
|
|
||||||
the Work or Derivative Works thereof, You may choose to offer,
|
|
||||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
|
||||||
or other liability obligations and/or rights consistent with this
|
|
||||||
License. However, in accepting such obligations, You may act only
|
|
||||||
on Your own behalf and on Your sole responsibility, not on behalf
|
|
||||||
of any other Contributor, and only if You agree to indemnify,
|
|
||||||
defend, and hold each Contributor harmless for any liability
|
|
||||||
incurred by, or claims asserted against, such Contributor by reason
|
|
||||||
of your accepting any such warranty or additional liability.

||||||

# libcontainer: what's next?
|
|
||||||
|
|
||||||
This document is a high-level overview of where we want to take libcontainer next.
|
|
||||||
It is a curated selection of planned improvements which are either important, difficult, or both.
|
|
||||||
|
|
||||||
For a more complete view of planned and requested improvements, see [the Github issues](https://github.com/opencontainers/runc/libcontainer/issues).
|
|
||||||
|
|
||||||
To suggest changes to the roadmap, including additions, please write the change as if it were already in effect, and make a pull request.
|
|
||||||
|
|
||||||
## Broader kernel support
|
|
||||||
|
|
||||||
Our goal is to make libcontainer run everywhere, but currently libcontainer requires Linux version 3.8 or higher. If you’re deploying new machines for the purpose of running libcontainer, this is a fairly easy requirement to meet. However, if you’re adding libcontainer to an existing deployment, you may not have the flexibility to update and patch the kernel.
|
|
||||||
|
|
||||||
## Cross-architecture support
|
|
||||||
|
|
||||||
Our goal is to make libcontainer run everywhere. Recently libcontainer has
|
|
||||||
expanded from its initial support for x86_64 systems to include POWER (ppc64
|
|
||||||
little and big endian variants), IBM System z (s390x 64-bit), and ARM. We plan
|
|
||||||
to continue expanding architecture support such that libcontainer containers
|
|
||||||
can be created and used on more architectures.
