Hi,
What is the correct way to clean old container images and volumes on CoreOS?
podman system prune --all --volumes
in a systemd timer?
I just freed 48GiB.

Yeah. There might be a better way, but timers seem like a good approach. For our builders we’re using a timer: https://github.com/coreos/fedora-coreos-pipeline/blob/aa70ee8148c94c39b2fbd8571653c5f604f2cbae/multi-arch-builders/builder-common.bu#L75-L104

This example is specific to our needs but here is what it does:
podman image prune --force
podman image prune --all --force --filter until=48h
podman container prune --force
podman volume prune --force --filter="label!=persistent"
persistent
label
