# DTR system requirements
|
||
|
||
Docker Trusted Registry can be installed on-premises or on the cloud.
|
||
Before installing, be sure your infrastructure has these requirements.
|
||
|
||
## Software requirements
|
||
|
||
To install DTR on a node, that node node must be part of a Docker Universal
|
||
Control Plane 1.1 cluster.
|
||
|
||
## Ports used
|
||
|
||
When installing DTR on a node, make sure the following ports are open on that
|
||
node:
|
||
|
||
| Direction | Port | Purpose |
|
||
|:---------:|:-----|:---------------------------------------------------------------------------------|
|
||
| in | 80 | Web app and API client access to DTR. |
|
||
| in | 443 | Web app and API client access to DTR. |
|
||
| out | 443 | Check if new versions are available, and send anonymous usage reports to Docker. |
|
||
|
||
The inbound ports are configurable.
|
||
|
||
DTR collects anonymous usage metrics, to help us improve it. These metrics
|
||
are entirely anonymous, don’t identify your company, users, applications,
|
||
or any other sensitive information. You can disable this on the DTR settings
|
||
page.
