This repository hosts open source components of Docker CE products. The
master branch serves to unify the upstream components on a regular
basis. Long-lived release branches host the code that goes into a product
version for the lifetime of the product.
This repository is solely maintained by Docker, Inc.
There are separate issue-tracking repos for the end user Docker CE products specialized for a platform. Find your issue or file a new issue for the platform you are using:

Main development of new features should be directed towards the upstream
git repos. The
master branch of this repo will periodically pull in new
changes from upstream to provide a point for integration.
Branching for release
When a release is started for Docker CE, a new branch will be created
master. Branch names will be
YY.MM to represent the time-based
release version of the product, e.g.
Adding fixes to release branch
Note: every commit of a fix should affect files only within one component directory.
Fix available upstream
A PR cherry-picking the necessary commits should be created against the release branch. If the the cherry-pick cannot be applied cleanly, the logic of the fix should be ported manually.
No fix yet
First create the PR with the fix for the release branch. Once the fix has been merged, be sure to port the fix to the respective upstream git repo.
There will be a git tag for each release candidate (RC) and general availablilty (GA) release. The tag will only point to commits on release branches.
