Release tools

Introduction

This directory contains tools for Kata Containers releases.

update-repository-version.sh

This script creates a GitHub pull request (a.k.a PR) to change the version in all the Kata repositories.

For more information on using the script, run the following:

$ ./update-repository-version.sh -h

Update Kata projects to a new version

Kata Containers is divided into multiple projects. With each release, all project versions are updated to keep the version consistent.

To update all versions for all projects, use the following:

$ make bump-kata-version NEW_VERSION=<new-version>

The makefile target bump-kata-version creates a GitHub pull request in the Kata repositories. These pull requests are tested by the Kata CI to ensure the entire project is working prior to the release. Next, the PR is approved and merged by Kata Containers members.

tag_repos.sh

After all the Kata repositories are updated with a new version, they need to be tagged.

The tag_repos.sh script is used to create tags for the Kata Containers repositories. This script ensures that all the repositories are in the same version (by checking the VERSION file).

The script creates an annotated tag for the new release version for the following repositories:

  • agent
  • proxy
  • runtime
  • shim
  • throttler

The script also tags the tests and osbuilder repositories to make it clear which versions of these supporting repositories are used for the release.
