Call service from specific node
Scenario: System of multiple nodes able to be configured during runtime via one master. Idea: every node provides a service (ex: configure_node(config)) which can be called by the master. Each node is uniquely named and does a job specific to the configuration it got.
Problem: I cant find anything about calling a service on a specific node (ex: NodeA/configure_node). Of course it could be realised using Pub/Sub but I would appreciate the RPC like features of the services. Is there anything I am missing?
