Listening Processes

In MetalK8s context several processes are deployed and they need to communicate with each other, sometimes locally, sometimes between machines in the cluster, or with the end user.

Depending on their :ref:`roles <node-roles>`, nodes must have several addresses available for MetalK8s processes to bind.
