are supported on Windows, and all manager nodes in the swarm must run on Linux.
Follow these steps to enable a worker node on Windows.
1. Install UCP on a Linux distribution.
2. Install Docker EE on Windows Server 2016.
2. Install Docker Enterprise Edition (*Docker EE*) on Windows Server 2016.
3. Configure the Windows node.
4. Join the Windows node to the swarm.
## Install UCP
To install UCP, follow the instructions in
[Learn how to install Docker Universal Control Plane on production](/datacenter/ucp/2.2/guides/admin/install/).
Install UCP on a Linux distribution.
[Learn how to install UCP on production](../install/index.md).
UCP requires Docker EE version 17.06 or later.
For internal development, you need to `docker login` and pull
the UCP images manually. For Beta, the images will be available publicly.

## Install Docker EE on Windows Server 2016
Install Docker Enterprise Edition (*Docker EE*) on a Windows
Server 2016 instance to enable joining a swarm that's managed by UCP.
Follow the instructions in
[Install Docker Enterprise Edition for Windows Server 2016](/docker-ee-for-windows/install/#using-a-script-to-install-docker-ee).
For internal development, install the dev binaries in the zip archive at
[windows/amd64/docker-17.06.0-dev.zip](https://master.dockerproject.org/windows/amd64/docker-17.06.0-dev.zip),
because you need version 17.06 or later to join a UCP swarm. For Beta, the binaries
will be available publicly at [download.docker.com](https://download.docker.com/components/engine/windows-server).

### Compatibility with daemon.json
The script may be incompatible with installations that use a config file at
`C:\ProgramData\docker\config\daemon.json`. If you use such a file, make sure
that the daemon runs on port 2376 and that it uses certificates located in
`C:\ProgramData\docker\daemoncerts`. If certificates don't exist in this
directory, run `ucp-agent-win generate-certs`, as shown in Step 2 of the
[Set up certs for the dockerd service](#set-up-certs-for-the-dockerd-service)
procedure.
In the daemon.json file, set the `tlscacert`, `tlscert`, and `tlskey` options
to the corresponding files in `C:\ProgramData\docker\daemoncerts`:
```json
{

"debug": true,
"tls": true,

## Join the Windows node to the swarm
Now you can join the UCP cluster by using the `docker swarm join` command that's
provided by the UCP web UI. For more info, see
[Join worker nodes](/datacenter/ucp/2.2/guides/admin/install/#step-7-join-worker-nodes).
