Description
This is a feature request for listing init PID and namespace info easily, eg, by adding a -v (for verbose) flag to docker ps. Here's a simple prototype in bash to show what I mean:
# ./dockerpsv.sh
CONTAINER NAME PID PATH CGROUP IPC MNT NET PID USER UTS
host bgregg-xenial-bpf-i- 1 systemd 4026531835 4026531839 4026531840 4026532197 4026531836 4026531837 4026531838

In my prototype (not shown above), I color namespaces red that match the host, to make it easy to see which namespaces are shared with the host.
