We have a ESXi env, and we setup one VM and installed docker, then we clone it into multiple VMs, but we found the docker engine ID is the same for all the docker engines, and couldn't find a way to change it. This prevents us to use swarm to create cluster properly. Anything we missed?

docker info output:

Containers: 12
Images: 251
Storage Driver: aufs
Root Dir: /var/lib/docker/aufs
Backing Filesystem: extfs
Dirs: 435
Execution Driver: native-0.2
Kernel Version: 3.16.0-30-generic
Operating System: Ubuntu 14.04.2 LTS
CPUs: 2
Total Memory: 15.67 GiB

I ran into something similar. I was able to fix this by deleting our docker key.json file then restarting the daemon. For me the file was in /etc/docker/key.json
