Connecting to a NiFi Registry
To connect NiFi to a Registry, select Controller Settings from the Global Menu.
This displays the NiFi Settings window. Select the Registry Clients tab and click the
+ button in the upper-right corner to register a new Registry client.
In the Add Registry Client window, provide a name and URL.
Click "Add" to complete the registration.
Versioned flows are stored and organized in registry buckets. Bucket Policies and Special Privileges configured by the registry administrator determine which buckets a user can import versioned flows from and which buckets a user can save versioned flows to. Information on Bucket Policies and Special Privileges can be found in the NiFi Registry User Guide (https://nifi.apache.org/docs/nifi-registry-docs/html/user-guide.html).
