[caasp-beta] docker service down on master ?

[Rafael Fernández López]

Hello,

It looks like etcd lost some important information.

What was the size of the cluster? Was the master server the only one
that was rebooted?

From the kubernetes master node, can you run the following command:

etcdctl ls -r /


Thank you,
Rafael Fernández López.
