Docker Trusted Registry system requirementsEstimated reading time: 1 minute
Docker Trusted Registry can be installed on-premises or on the cloud. Before installing, be sure your infrastructure has these requirements.
You can install DTR on-premises or on a cloud provider. To install DTR, all nodes must:
- Be a worker node managed by Universal Control Plane.
- Have a fixed hostname.
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.
