I'd like to limit the number of pids a container can consume on RHEL 8.3 to provide protection against things like bash fork bombs. Ideally I would want to do this in a rootless container but when I do

$ podman run -it -u user1 --pids-limit 42 frog

I get:

Error: container_linux.go:370: starting container process caused: process_linux.go:459: container init caused: process_linux.go:422: setting cgroup config for procHooks process caused: cannot set pids limit: container could not join or create cgroup: OCI runtime error

I can however run the same podman command as root without issue.

Is there a method to do this as non root? Or a better solution using systemd?

Thanks, Ed
