Install UCP on a 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 anode into a manager, and installs Docker Universal Control Plane (UCP).

When installing UCP you can customize:

• The UCP web server certificates. 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, which you can accomplish by bind-mounting the file at /config/docker_subscription.lic in the tool. For example, -v /path/to/my/config/docker_subscription.lic:/config/docker_subscription.lic or by specifying the --license $(cat license.lic) option.

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.

Options

Option	Description
--debug, D	Enable debug mode
--jsonlog	Produce json formatted output for easier parsing
--interactive, i	Run in interactive mode and prompt for configuration values
--admin-username	The UCP administrator username
--admin-password	The UCP administrator password
--san	Add subject alternative names to certificates (e.g. --san www1.acme.com --san www2.acme.com)
--host-address	The network address to advertise to other nodes. Format: IP address or network interface name
--data-path-addr	Address or interface to use for data path traffic. Format: IP address or network interface name
--controller-port	Port for the web UI and API
--kube-apiserver-port	Port for the Kubernetes API server (default: 6443)
--swarm-port	Port for the Docker Swarm manager. Used for backwards compatibility
--swarm-grpc-port	Port for communication between nodes
--cni-installer-url	Deprecated feature. A URL pointing to a Kubernetes YAML file to be used as an installer for the CNI plugin of the cluster. If specified, the default CNI plugin is not installed. If the URL uses the HTTPS scheme, no certificate verification is performed.

| --unmanaged-cni | flag to indicate if cni provider is calico and managed by UCP (calico is the default CNI provider). The default value is "true" when using the default Calico CNI. |

| --pod-cidr | Kubernetes cluster IP pool for the pods to allocated IPs from (Default: 192.168.0.0/16) |
| --cloud-provider | The cloud provider for the cluster |
| --dns | Set custom DNS servers for the UCP containers |
| --dns-opt | Set DNS options for the UCP containers |
| --dns-search | Set custom DNS search domains for the UCP containers |
| --unlock-key | The unlock key for this swarm-mode cluster, if one exists. |
| --existing-config | Use the latest existing UCP config during this installation. The install fails if a config is not found.
| --force-minimums | Force the install/upgrade even if the system doesn't meet the minimum requirements.
| --pull | Pull UCP images: always, when missing, or never
| --registry-username | Username to use when pulling images

| --kv-timeout | Timeout in milliseconds for the key-value store
| --kv-snapshot-count | Number of changes between key-value store snapshots
| --swarm-experimental | Enable Docker Swarm experimental features. Used for backwards compatibility
| --disable-tracking | Disable anonymous tracking and analytics
| --disable-usage | Disable anonymous usage reporting
| --external-server-cert | Use the certificates in the ucp-controller-server-certs volume instead of generating self-signed certs during installation
| --preserve-certs | Don't generate certificates if they already exist
| --binpack | Set the Docker Swarm scheduler to binpack mode. Used for backwards compatibility
| --random | Set the Docker Swarm scheduler to random mode. Used for backwards compatibility
| --external-service-lb | Set the external service load balancer reported in the UI
| --enable-profiling | Enable performance profiling
| --license | Add a license: e.g. --license "$(cat license.lic)"
| --force-insecure-tcp | Force install to continue even with unauthenticated Docker Engine ports
