Can you share your host's operating system and docker's version / source installed from?

In docker using Init: true relies on the host's init system if none is provided in container.

Is docker-init present in your host's /sbin or /usr/libexec/docker directory?

I see you running Ubuntu, maybe apparmor is messing with docker's abilities?
