On my environment, the name=systemd entry in /proc/self/cgroup
looks like:
13:name=systemd:/docker/917b388b40c70b17a3283d852d38bfcdc84d1bf8242e32a779eacd98a610e499
Kubelet periodically complains like:

Allow the kubelet resolv-conf flag to be set, or automatically
discovered from /etc/resolv.conf & /run/systemd/resolve/resolv.conf if
no loopback devices are present, or create our own which points to
nameserver 8.8.8.8
