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 1.10 or higher. Learn about the
[operating systems supported by CS Docker Engine](/cs-engine/install/).
* 2.00 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 |
|:-------------------|:---------:|:------------------------|:---------------------------------------------------------------------------|
| controllers, nodes | in | TCP 443 (configurable) | Web app and CLI client access to UCP. |
| controllers, nodes | in | TCP 2375 | Heartbeat for nodes, to ensure they are running. |
| controllers | in | TCP 2376 (configurable) | Swarm manager accepts requests from UCP controller. |
| controllers, nodes | in, out | TCP + UDP 4789 | Overlay networking. |
| controllers, nodes | in, out | TCP + UDP 7946 | Overlay networking. |
| controllers, nodes | in | TCP 12376 | Proxy for TLS, provides access to UCP, Swarm, and Engine. |
| controller | in | TCP 12379 | Internal node configuration, cluster configuration, and HA. |
| controller | in | TCP 12380 | Internal node configuration, cluster configuration, and HA. |
| controller | in | TCP 12381 | Proxy for TLS, provides access to UCP. |
| controller | in | TCP 12382 | Manages TLS and requests from swarm manager. |
| controller | in | TCP 12383 | Used by the authentication storage backend. |
| controller | in | TCP 12384 | Used by authentication storage backend for replication across controllers. |
| controller | in | TCP 12385 | The port where the authentication API is exposed. |
| controller | in | TCP 12386 | Used by the authentication worker. |
## Compatibility and maintenance lifecycle
Docker Datacenter is a software subscription that includes 3 products:
* CS Docker Engine,
* Docker Trusted Registry,
* Docker Universal Control Plane.
[Learn more about the maintenance lifecycle for these products](http://success.docker.com/Get_Help/Compatibility_Matrix_and_Maintenance_Lifecycle).
