Docker swarm join crashes system on CentOS 7.2/VMware


(Mdaniels) #1

Using systemd to start docker. This occurs on multiple machines which have had docker 1.12 RC versions on them in the past and now have been upgraded to the final 1.12 release. Docker starts ok at boot but whenever I make some config changes and try to restart docker, the machine reboots (every time). I have other machines using the same CentOS image that don’t exhibit this problem. Any idea where I would start tracking this down?

The CentOS 7.X is supported but preferably use a cloud provider such as AWS.

Wiping out /var/lib/docker seems to have fixed it for now.

As soon as I joined the nodes back to a swarm the same behavior happened again. If I leave the swarm I can restart docker w/o any issues.
