Note: It is recommended to install the exact same version of the CS Docker Engine across all nodes to avoid experiencing any issues during and after the install. So on each host that you want to be part of the UCP cluster, [install CS Docker Engine 1.12.0 or above](https://docs.docker.com/docker-trusted-registry/cs-engine/install/). 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.
