## Step 2. Install UCP
DTR requires Docker Universal Control Panel (UCP) to run. If UCP is not yet installed, refer to [install UCP for production](/ee/ucp/admin/install/).

Since DTR requires Docker Universal Control Plane (UCP)
to run, you need to [install UCP](/ee/ucp/admin/install/) on all the nodes
where you plan to install DTR.
DTR needs to be installed on a worker node that is being managed by UCP.
You cannot install DTR on a standalone Docker Engine.
DTR and UCP must not be installed on the same node, due to the potential for resource and port conflicts, Instead, install DTR on worker nodes that will be managed by UCP. Note also that DTR cannot be installed on a standalone Docker Engine.
