-------------------------------------
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.
