I was recently building up a Docker EE lab to go deeper in some of my weak areas after passing the Docker Certified Associate certification. The following commands walk you through how to install the Univeral Control Plane on a newly created Ubuntu 18.04 server.
docker image pull docker/ucp:latest
PRIVATE_IP=172.16.1.212
docker container run --rm -it --name ucp \
-v /var/run/docker.sock:/var/run/docker.sock \
docker/ucp:3.1.5 install \
--host-address $PRIVATE_IP \
--interactive
In this particular example I set a variable of PRIVATE_IP and for clarity this was set to the host of my Docker Swarm manager (leader) node. I think most of the time it pulls this automatically but I found this to be more stable if you hard code it.
Please note there is another switch which must be used if you are deploying this on Azure IaaS VMs.
The following switch should be added --cloud-provider Azure
You may also want to review this article, for another pre step which should be done before deploying UCP on Azure VMs.
