How to update the build image

The build image currently can only be updated by a Cortex maintainer. If you’re not a maintainer you can still open a PR with the changes, asking a maintainer to assist you publishing the updated image. The procedure is:

  1. Update build-image/Docker
  2. Build the image running make build-image/.uptodate
  3. Publish the image to the repository running docker push (this can only be done by a maintainer)
  4. Replace the image tag in .github/workflows/* (there may be multiple references)
  5. Open a PR and make sure the CI with new build-image passes
