CNV supports to create container disks and than attaching them to VMs and boot the VM from them. The ask is to document this functionality. Document URL: Section Number and Name: Describe the issue: Suggestions for improvement: Additional information:
Upstream has cat << END > Dockerfile FROM scratch ADD fedora25.qcow2 /disk/ END docker build -t vmdisks/fedora25:latest . docker push vmdisks/fedora25:latest We should use podman and rhel.
Reintroducing the target milestone. containerDisks are already being used. We should document when they can be used (immutable filesystems) and how to create them.
