## About
This directory contains a collection of scripts used to build and manage this
repository. If there are any issues regarding the intention of a particular
script (or even part of a certain script), please reach out to us.
It may help us either refine our current scripts, or add on new ones
that are appropriate for a given use case.
## DinD (dind.sh)
DinD is a wrapper script which allows Docker to be run inside a Docker
container. DinD requires the container to
be run with privileged mode enabled.
## Generate Authors (generate-authors.sh)
Generates AUTHORS; a file with all the names and corresponding emails of
individual contributors. AUTHORS can be found in the home directory of
this repository.
## Install (install.sh)
Executable install script for installing Docker. If updates to this are
desired, please use hack/release.sh during a normal release. The following
one-liner may be used for script hotfixes:
- `aws s3 cp --acl public-read hack/install.sh s3://get.docker.com/index`
## Make
There are two make files, each with different extensions. Neither are supposed
to be called directly; only invoke `make`. Both scripts run inside a Docker
container.
### make.ps1
- The Windows native build script that uses PowerShell semantics; it is limited
unlike `hack\make.sh` since it does not provide support for the full set of
operations provided by the Linux counterpart, `make.sh`. However, `make.ps1`
does provide support for local Windows development and Windows to Windows CI.
More information is found within `make.ps1` by the author, @jhowardmsft
### make.sh
- Referenced via `make test` when running tests on a local machine,
or directly referenced when running tests inside a Docker development container.
- When running on a local machine, `make test` to run all tests found in
`test`, `test-unit`, `test-integration-cli`, and `test-docker-py` on
your local machine. The default timeout is set in `make.sh` to 60 minutes
(`${TIMEOUT:=60m}`), since it currently takes up to an hour to run
all of the tests.
- When running inside a Docker development container, `hack/make.sh` does
not have a single target that runs all the tests. You need to provide a
single command line with multiple targets that performs the same thing.
An example referenced from [Run targets inside a development container](https://docs.docker.com/opensource/project/test-and-docs/#run-targets-inside-a-development-container): `root@5f8630b873fe:/go/src/github.com/moby/moby# hack/make.sh dynbinary binary cross test-unit test-integration-cli test-docker-py`
- For more information related to testing outside the scope of this README,
refer to
[Run tests and test documentation](https://docs.docker.com/opensource/project/test-and-docs/)
## Release (release.sh)
Releases any bundles built by `make` on a public AWS S3 bucket.
For information regarding configuration, please view `release.sh`.
## Vendor (vendor.sh)
A shell script that is a wrapper around Vndr. For information on how to use
this, please refer to [vndr's README](https://github.com/LK4D4/vndr/blob/master/README.md)

# OCI Image Format Specification
<div>
<a href="https://travis-ci.org/opencontainers/image-spec">
<img src="https://travis-ci.org/opencontainers/image-spec.svg?branch=master"></img>
</a>
</div>
The OCI Image Format project creates and maintains the software shipping container image format spec (OCI Image Format).
**[The specification can be found here](spec.md).**
This repository also provides [Go types](specs-go), [intra-blob validation tooling, and JSON Schema](schema).
The Go types and validation should be compatible with the current Go release; earlier Go releases are not supported.
Additional documentation about how this group operates:
- [Code of Conduct](https://github.com/opencontainers/tob/blob/d2f9d68c1332870e40693fe077d311e0742bc73d/code-of-conduct.md)
- [Roadmap](#roadmap)
- [Releases](RELEASES.md)
- [Project Documentation](project.md)
The _optional_ and _base_ layers of all OCI projects are tracked in the [OCI Scope Table](https://www.opencontainers.org/about/oci-scope-table).
## Running an OCI Image
The OCI Image Format partner project is the [OCI Runtime Spec project](https://github.com/opencontainers/runtime-spec).
The Runtime Specification outlines how to run a "[filesystem bundle](https://github.com/opencontainers/runtime-spec/blob/master/bundle.md)" that is unpacked on disk.
At a high-level an OCI implementation would download an OCI Image then unpack that image into an OCI Runtime filesystem bundle.
At this point the OCI Runtime Bundle would be run by an OCI Runtime.
This entire workflow supports the UX that users have come to expect from container engines like Docker and rkt: primarily, the ability to run an image with no additional arguments:
* docker run example.com/org/app:v1.0.0
* rkt run example.com/org/app,version=v1.0.0
To support this UX the OCI Image Format contains sufficient information to launch the application on the target platform (e.g. command, arguments, environment variables, etc).
## FAQ
**Q: Why doesn't this project mention distribution?**
A: Distribution, for example using HTTP as both Docker v2.2 and AppC do today, is currently out of scope on the [OCI Scope Table](https://www.opencontainers.org/about/oci-scope-table).
There has been [some discussion on the TOB mailing list](https://groups.google.com/a/opencontainers.org/d/msg/tob/A3JnmI-D-6Y/tLuptPDHAgAJ) to make distribution an optional layer, but this topic is a work in progress.
**Q: What happens to AppC or Docker Image Formats?**
A: Existing formats can continue to be a proving ground for technologies, as needed.
The OCI Image Format project strives to provide a dependable open specification that can be shared between different tools and be evolved for years or decades of compatibility; as the deb and rpm format have.
Find more [FAQ on the OCI site](https://www.opencontainers.org/faq).
## Roadmap
The [GitHub milestones](https://github.com/opencontainers/image-spec/milestones) lay out the path to the OCI v1.0.0 release in late 2016.
# Contributing
Development happens on GitHub for the spec.
Issues are used for bugs and actionable items and longer discussions can happen on the [mailing list](#mailing-list).
The specification and code is licensed under the Apache 2.0 license found in the `LICENSE` file of this repository.
## Discuss your design
The project welcomes submissions, but please let everyone know what you are working on.
Before undertaking a nontrivial change to this specification, send mail to the [mailing list](#mailing-list) to discuss what you plan to do.
This gives everyone a chance to validate the design, helps prevent duplication of effort, and ensures that the idea fits.
It also guarantees that the design is sound before code is written; a GitHub pull-request is not the place for high-level discussions.
Typos and grammatical errors can go straight to a pull-request.
When in doubt, start on the [mailing-list](#mailing-list).
## Weekly Call
The contributors and maintainers of all OCI projects have a weekly meeting Wednesdays at 2:00 PM (USA Pacific).
Everyone is welcome to participate via [UberConference web][UberConference] or audio-only: +1-415-968-0849 (no PIN needed).
An initial agenda will be posted to the [mailing list](#mailing-list) earlier in the week, and everyone is welcome to propose additional topics or suggest other agenda alterations there.
Minutes are posted to the [mailing list](#mailing-list) and minutes from past calls are archived [here][minutes].
## Mailing List
You can subscribe and join the mailing list on [Google Groups](https://groups.google.com/a/opencontainers.org/forum/#!forum/dev).
## IRC
OCI discussion happens on #opencontainers on Freenode ([logs][irc-logs]).
## Markdown style
To keep consistency throughout the Markdown files in the Open Container spec all files should be formatted one sentence per line.
This fixes two things: it makes diffing easier with git and it resolves fights about line wrapping length.
For example, this paragraph will span three lines in the Markdown source.
## Git commit
### Sign your work
The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it 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 Certificate of Origin
Version 1.1
Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
660 York Street, Suite 102,
San Francisco, CA 94110 USA
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
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@gmail.com>
using your real name (sorry, no pseudonyms or anonymous contributions.)
You can add the sign off when creating the git commit via `git commit -s`.
### Commit Style
Simple house-keeping for clean git history.
Read more on [How to Write a Git Commit Message](http://chris.beams.io/posts/git-commit/) or the Discussion section of [`git-commit(1)`](http://git-scm.com/docs/git-commit).
1. Separate the subject from body with a blank line
2. Limit the subject line to 50 characters
3. Capitalize the subject line
4. Do not end the subject line with a period
5. Use the imperative mood in the subject line
6. Wrap the body at 72 characters
7. Use the body to explain what and why vs. how
* If there was important/useful/essential conversation or information, copy or include a reference
8. When possible, one keyword to scope the change in the subject (i.e. "README: ...", "runtime: ...")
