ClusterControl provides RPC interfaces for the CMON controller, and these interfaces are exposed in two different versions:
It’s recommended to use the RPC v2, whenever possible. Please note that the RPC v2 API calls are available only using secure (TLS) connections, where encryption is mandatory. The RPC v2 also uses an authentication call, and very few of the calls are available to be used without authenticating first.
By default, the encrypted communication can be used through port 9501 and the RPC v2 requests are server served on the /v2 path (e.g. /v2/clusters).
