Steps to Reproduce:
Make the tutorial Run Replicated Stateful Application of k8s docs.

Link to docs:
https://kubernetes.io/docs/tasks/run-application/run-replicated-stateful-application/

Results:
After to create the statefulset (with implicit PersistentVolume and PersistentVolumeClaim that aren't in the tutorial). the replica of the pod mysql-0 won't to be created and will report CrashLoopBackOff status with the log below:

$ kbk logs pod/mysql-0 
Error from server (BadRequest): a container name must be specified for pod mysql-0, choose one of: [mysql xtrabackup] or one of the init containers: [init-mysql clone-mysql]

I've discovered that this is a bug of docker with IPTABLES in the node host and are specified in Upgrading docker 1.13 on nodes causes outbound container traffic to stop working issue of kubernetes.

But when I tried to change default iptables forward (running iptables -P FORWARD ACCEPT on the node - virtualbox VM) nothing happed and still persists. I try to disable ufw firewall to, but again, persists.

@mayconfsbrito Do you solve this issue?

[mayconfsbrito]

@jianzi123 I've disabled the firewall completely
