Whenever I reboot a host it fails to reconnect to rancher server. However, once I log into the host and run “docker ps” the host immediately reconnects. I am using Kubernetes for my environment and CoreOS stable (1520.7.0) on my hosts. Any help would be greatly appreciated. Thanks!
Try enabling it on boot:
sudo systemctl enable docker
Oh man, I just assumed CoreOS would start Docker at boot. That was totally the answer. So simple. Thank you so much.
