Releasing a new version

Releasing a new version of Tanka requires a couple of manual and automated steps. This guide will give you a runbook on how to do them in the right order.

1. Create a release tag

  1. Pull the latest changes from the main branch to your local clone.
  2. Create a new tag with the prefix v (e.g. v0.28.0).
  3. Push that tag back to GitHub.

This starts multiple GitHub workflows that will produce binaries, a Docker image, and also a new GitHub release that is marked as draft.

2. Add changelog to the release notes

Once all these actions have finished, go to https://github.com/grafana/tanka/releases and you should see the new draft release. Click the pencil icon (“edit”) at the top-right and go to the last line of the text body. Now hit the “Generate release notes” button to add a changelog to the end of the release notes.

3. Publish the release notes

Once you’ve check that the release looks fine (e.g. no broken links, no missing version numbers in the download paths) click the “Publish release” button.
