Once you get your trial license, you can install Docker Enterprise’s Universal Control Plane and Docker Trusted Registry on Linux Servers. Windows Servers can only be used as Universal Control Plane Worker Nodes.

Learn more about the Universal Control Plane’s system requirements here. Also, make sure the hosts are running one of the supported operating systems from Docker Enterprise’s Compatibility Matrix.

Step 1: Install Docker Enterprise Container Engine

Select a platform and click through to install the Docker Enterprise container engine on all hosts you want to manage.

Step 2: Install Universal Control Plane

Docker Universal Control Plane (UCP) allows managing from a centralized place your images, applications, networks, and other computing resources.

Use ssh to log in to the host where you want to install UCP and run:

docker container run --rm -it --name ucp \
  -v /var/run/docker.sock:/var/run/docker.sock \
  docker/ucp:3.2.4 install \
  --host-address <node-ip-address> \

This runs the install command in interactive mode, so that you’re prompted for any necessary configuration values.

Learn more about the UCP installation.

What about Windows? When you have UCP installed, you can join Windows worker nodes to a swarm.

Step 3: License your installation

Now that UCP is installed, you need to license it. In your browser, navigate to the UCP web UI, log in with your administrator credentials and upload your license.

Step 4: Join more nodes to UCP

Join more nodes so that you can manage them from UCP. Go to the UCP web UI and navigate to the Nodes page.

Nodes page

Click the Add Node button to add a new node.

Add node page

Check Add node as a manager to join the node as a manager to provide replication and make UCP highly available. For a highly available installation, make sure you have 3, 5, or 7 manager nodes.

Copy the command to your clipboard, and run it on every node that you want to be managed by UCP. After you run the command in the node, the node will show up in the UP web UI.

Step 5: Install Docker Trusted Registry

Docker Trusted Registry (DTR) is a private image registry so that you can manage who has access to your Docker images. DTR needs to be installed on a node that is being managed by UCP.

Use ssh to log in to the host where you already installed UCP, and run:

docker container run -it --rm \
  docker/dtr:2.7.4 install \
  --ucp-node <node-hostname> \

Where the --ucp-node is the hostname of the UCP node where you want to deploy DTR. --ucp-insecure-tls tells the installer to trust the certificates used by UCP.
