Registry Release Checklist

  1. Compile release notes detailing features and since the last release.

Update the CHANGELOG.md file and create a PR to master with the updates. Once that PR has been approved by maintainers the change may be cherry-picked to the release branch (new release branches may be forked from this commit).

  1. Update the version file: https://github.com/docker/distribution/blob/master/version/version.go

  2. Update the MAINTAINERS (if necessary), AUTHORS and .mailmap files.

make AUTHORS
  1. Create a signed tag.

Distribution uses semantic versioning. Tags are of the format vx.y.z[-rcn]. You will need PGP installed and a PGP key which has been added to your Github account. The comment for the tag should include the release notes, use previous tags as a guide for formatting consistently. Run git tag -s vx.y.z[-rcn] to create tag and git -v vx.y.z[-rcn] to verify tag, check comment and correct commit hash.

  1. Push the signed tag

  2. Create a new release. In the case of a release candidate, tick the pre-release checkbox.

  3. Update the registry binary in distribution library image repo by running the update script and opening a pull request.

  4. Update the official image. Add the new version in the official images repo by appending a new version to the registry/registry file with the git hash pointed to by the signed tag. Update the major version to point to the latest version and the minor version to point to new patch release if necessary. e.g. to release 2.3.1

2.3.1 (new)

2.3.0 -> 2.3.0 can be removed

2 -> 2.3.1

2.3 -> 2.3.1

  1. Build a new distribution/registry image on Docker hub by adding a new automated build with the new tag and re-building the images.
