Ok, I have everything installed. But when trying the busybox test I get
Error response from daemon: Error looking up volume plugin flocker: Plugin not found
I noticed that the docs say that on upgrade of the plugin the docker daemon should be restarted.
But nothing is said about restarting during/after the initial install.
In any case I restarted both the docker and the plugin, but still same error.
Any help would be appreciated.
