Get Podman container ID from inside itself

What is the most reliable way to get the Podman container id from inside itself?

In Docker I solved it like this: basename $(cat /proc/1/cpuset). Unfortunately, this doesn't work for Podman, as it returns /.

I already tried cat /etc/hostname in Podman, however this doesn't work if the container is started with podman run --network host.

Solution

  • You should be able to get it by peeking /proc/self/cgroup
