Release notes
As the heroku/builder:20
image used by the Auto Build component of Auto DevOps was deprecated upstream, we are moving to the heroku/builder:22
image. The new images are based on ubuntu:22.04
instead of ubuntu:20.04
and the respective packages. Otherwise, they support the same version 0.18.x
cloud native buildpack lifecycle APIs.
This breaking change arrives outside a GitLab major release as we need to accommodate a breaking change upstream and the upgrade is unlikely to break app developers' pipelines. If needed, users can manually configure to user the heroku/builder:20
and skip the errors to revert the changes.
