Marcos Nils, the PWD link seems to be broken:
"Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?"
It is still possible to open PWD, "git clone" the stack from Github and start Docker EE (UCP) manually:
git clone https://github.com/play-with-docker/stacks.git
docker stack deploy -c stack.yml ucp
The "stack.yml" can also be edited to run the latest UCP (version "2.2.0").
