Docker Trusted Registry can be installed on-premises or on the cloud. Before installing, be sure your infrastructure has these requirements.
You can only install DTR on a node that is being managed by Docker Universal Control Plane.
When installing DTR on a node, make sure the following ports are open on that node:
|in||80/tcp||Web app and API client access to DTR.|
|in||443/tcp||Web app and API client access to DTR.|
These ports are configurable when installing DTR.
