docker/ucp install
Estimated reading time: 5 minutesInstall UCP on this node
Usage
docker container run --rm -it \
--name ucp \
-v /var/run/docker.sock:/var/run/docker.sock \
docker/ucp \
install [command options]
Description
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 theca.pem
,cert.pem
, andkey.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, 12379, 12380, 12381, 12382, 12383, 12384, 12385, 12386, 12387
- 4789 (udp) and 7946 (tcp/udp) for overlay networking
If you have SELinux policies enabled for your Docker install, you will need to
use docker container run --rm -it --security-opt label=disable ...
when running this
command.

--dns-search |
Set custom DNS search domains for the UCP containers |
--unlock-key |
