I could reproduce with a full blown ubuntu, I'm trying to find the issue.
With docker inspect, you can get the Pid of the container you want to debug on.
Then as root you create if it doesn't exist /var/run/netns, then you link /proc/$pid/ns/net /var/run/netns/container_name.
Then you can issue commands like ip netns exec container_name ip addr, ip netns exec container_name ping etc...
I'm still looking at what is creating this behavior.
