$ podman infoERRO[0000] 'overlay' is not supported over overlayfsError: could not get runtime: 'overlay' is not supported over overlayfs: backing file system is unsupported for this graph driver I am using the Jenkins Kubernetes plugin to write CI/CD pipelines that run as containers within a Kubernetes cluster. I've been successful at writing pipelines that use a Docker-in-Docker container to run docker build and docker push commands.
However, running a Docker client and a Docker Daemon inside a container makes the CI/CD environment very bloated, hard to configure, and just not ideal to work with. So I figured I could use podman to build Docker images from Dockerfiles without using a fat Docker daemon.
