             Summary: Hierarchical C2 support
                 Key: MINIFI-272
                 URL: https://issues.apache.org/jira/browse/MINIFI-272
             Project: Apache NiFi MiNiFi
          Issue Type: New Feature
            Reporter: Bryan Rosander
         Attachments: c2-integration-test.png

MINIFI-238 introduced a C2 server that MiNiFi agents can poll for new configuration files.  In order for this to be useful on a larger scale, we'll need a way to structure the servers such that they are reachable by the edge nodes while still having a central place from which to distribute changed configuration.

To that end, a delegating configuration provider should allow for arbitrary hierarchical structures of C2 servers.

A docker-compose integration test that simulates several different possible network and delegation configurations will help to prove out the concept.

Attached is an image of the integration test topology.  There is a central cluster network where the authoritative C2 server resides.  There is a node able to connect directly to it in the edge1 network.  There is a delegating C2 server that bridges the cluster and edge2 networks.  The edge2 server listens for http requests and delegates over https.  There is a node on the edge3 network that requests directory from the authoritative C2 server through a squid proxy.
