|
|
|
|
Docker Universal Control Plane can be installed on-premises or on the cloud.
|
|
Before installing, be sure your infrastructure has these requirements.
|
|
|
|
## Hardware and software requirements
|
|
|
|
You can install UCP on-premises or on a cloud provider. To install UCP,
|
|
all nodes must have:
|
|
|
|
* Linux kernel version 3.10 or higher
|
|
* CS Docker Engine version 1.13.0 or higher
|
|
* 4.00 GB of RAM
|
|
* 3.00 GB of available disk space
|
|
* A static IP address
|
|
|
|
For highly-available installations, you also need a way to transfer files
|
|
between hosts.
|
|
|
|
## Ports used
|
|
|
|
When installing UCP on a host, make sure the following ports are open:
|
|
|
|
| Hosts | Direction | Port | Purpose |
|
|
|:------------------|:---------:|:------------------------|:----------------------------------------------------------------------------------|
|
|
| managers, workers | in | TCP 443 (configurable) | Port for the UCP web UI and API |
|
|
| managers | in | TCP 2376 (configurable) | Port for the Docker Swarm manager. Used for backwards compatibility |
|
|
| managers, workers | in | TCP 2377 (configurable) | Port for communication between swarm nodes |
|
|
| managers, workers | in, out | UDP 4789 | Port for overlay networking |
|
|
| managers, workers | in, out | TCP, UDP 7946 | Port for gossip-based clustering |
|
|
| managers, workers | in | TCP 12376 | Port for a TLS proxy that provides access to UCP, Docker Engine, and Docker Swarm |
|
|
| managers | in | TCP 12379 | Port for internal node configuration, cluster configuration, and HA |
|
|
| managers | in | TCP 12380 | Port for internal node configuration, cluster configuration, and HA |
|
|
| managers | in | TCP 12381 | Port for the certificate authority |
|
|
| managers | in | TCP 12382 | Port for the UCP certificate authority |
|
|
| managers | in | TCP 12383 | Port for the authentication storage backend |
|
|
| managers | in | TCP 12384 | Port for the authentication storage backend for replication across managers |
|
|
| managers | in | TCP 12385 | Port for the authentication service API |
|
|
| managers | in | TCP 12386 | Port for the authentication worker |
|
|
| managers | in | TCP 12387 | Port for the metrics service |
