Hi,

I have a custom built jenkins-master Docker image that essentially just puts the jenkins user in the root group so that the container can see the /var/sock/docker.socket when I mount it

If I enter the socket URL as the docker URL, the test button reports success but If I make a docker cloud with e.g. the evarga/jenkins-slave (SSH), I can see it spawn the slave container but then it times out in 60 seconds.

The slave image works fine as standalone and I can ssh into it with jenkins/jenkins just fine. Also, the slave image spawns fine (and works) if I configure jenkins to use the docker REST endpoint of the host
