For Gitlab ci/cd I have the following infrastructure:
There is a Gitlab instance, which is connected to a kubernetes cluster(crio engine),
via a gitlab kubernetes runner.
When there is a commit, the runner picks up the job and runs it in a kubernetes pod.
The first task for each project is to build a container and push it to a container registry, for later use.
The problem I have, is that when buildah bud ... runs inside of a kubernetes pod,
it fails mounting an overlay filesystem.
How can I enable mounting overlay filesystems inside of crio containers?
This is the output I have for buildah bud:
