## Step 2: Install CS Docker on all nodes
UCP requires you to install Docker CS Engine 1.10 or above on all nodes of
your UCP cluster.
UCP is a containerized application that requires CS Docker Engine 1.10.0 or
above to run. It is recommended to install the exact same version of the
CS Docker Engine on all nodes.
[Install CS Docker Engine](https://docs.docker.com/docker-trusted-registry/cs-engine/install/)
on each host that you want to be part of the UCP cluster.

In the case where you are creating a VM template with CS Engine already
installed, make sure that `/etc/docker/key.json` is not included in the image.
You can do this by simply removing `/etc/docker/key.json`. You can then restart
Docker on each node, which will generate new `/etc/docker/key.json` files.
