In k8s Pod, you can specify HostPID when container need access to Host PID (equivalent to --pid host).

Currently, this is not supported by podman kube play, which is problematic when trying to migrate Docker compose yaml to k8s yaml usable with podman

Did you try this against the main branch?

If yes, would you care to open a PR?

[fcrozat]

Yes, I checked main branch, it is not implemented.

Unforunately, I don't have enough go skills to implement it myself :(
