Docker crash on activating TLS

RancherOS
1

Hello,

On RancherOS 0.4.0, I’ve apply the method described here : http://docs.rancher.com/os/configuration/setting-up-docker-tls/ to activate TLS.

But when trying to restart the docker service :

sudo system-docker restart docker

Docker never restart, even after a reboot.
I obtain the following log in /var/log/messages :

panic: runtime error: index out of range

Yep, this is a known issue and we have a PR already created to fix the issue in.
