kuma-cp starts up, by default it listens on a few ports:
5677: the SDS server being used for propagating mTLS certificates across the data-planes.
5678: the xDS gRPC server implementation that the data-planes will use to retrieve their configuration.
5679: the Admin Server that serves Dataplane Tokens and manages Provided Certificate Authority
5680: the HTTP server that returns the health status of the control-plane.
5681: the HTTP API server that is being used by
kumactl, and that you can also use to retrieve Kuma's policies and - when running in
universal- that you can use to apply new policies.
5682: the HTTP server that provides the Envoy bootstrap configuration when the data-plane starts up.
5683: the HTTP server that exposes Kuma UI.
