[kubelet] [summary_sys_containers.go:47] Failed to get system container stats for "/system.slice/docker.service": failed to get cgroup stats for "/system.slice/docker.service": failed to get container info for "/system.slice/docker.service": unknown container "/system.slice/docker.service"

```

This error may appear in the kubelet logs after a reboot if kubelet starts after docker. In our experience this error is harmless. It’s possible to stop the error from appearing in the logs by restarting kubelet with `systemctl restart kubelet`.
