Mupx fails to work with docker for me

Sorry, Little stuck, How does this error get resolved?

x Invoking deployment process: FAILED

-----------------------------------STDERR-----------------------------------

Can you SSH into the remote server to make sure the docker daemon is running?

[remote] ~ > /etc/init.d/docker status

If it’s not running, try starting it as:

[remote] ~ > /etc/init.d/docker start

OK I got it work, I didn’t realize my dev-ops guy had already installed docker, so I was actually trying to install docker on the docker image, rather than the docker host. Once we figured that out, it went smoothly. I have to say that deployments are much faster with mupx rather than mup

Hope this helps anybody else new to docker.
