Estimated reading time: 3 minutes

Install UCP on this node


This command initializes a new swarm, turns this node into a manager, and installs Docker Universal Control Plane (UCP).

When installing UCP you can customize:

  • The certificates used by the UCP web server. Create a volume named ‘ucp-controller-server-certs’ and copy the ca.pem, cert.pem, and key.pem files to the root directory. Then run the install command with the ‘–external-server-cert’ flag.

  • The license used by UCP, by bind-mounting the file at ‘/config/docker_subscription.lic’ in the tool. E.g. -v /path/to/my/config/docker_subscription.lic:/config/docker_subscription.lic or by specifying with ‘–license “$(cat license.lic)”

If you’re joining more nodes to this swarm, open the following ports in your firewall:

  • 443 or the ‘–controller-port’
  • 2376 or the ‘–swarm-port’
  • 12376, 4789, 12379, 12380, 12381, 12382, 12383, 12384, 12385, 12386, 12387
  • 4789(udp) and 7946(tcp/udp) for overlay networking
