not be installed on the node you run the install command on. DTR will be
installed on the ucp worker defined by the `--ucp-node` flag.
As an example, you can SSH into a UCP node and install DTR from there. Running the installation command in interactive TTY or `-it` mode means you will be prompted for any required additional information. As an example, you could SSH into a UCP node and run the DTR install command
