-------------------------------
Summary: Configure advertised host name of Remote Process Group
Input Port
Key: NIFI-868
URL: https://issues.apache.org/jira/browse/NIFI-868
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Affects Versions: 0.2.1
Environment: Linux
Reporter: Chin Huang
The host given out to clients to connect to a Remote Process Group Input Port
is the host where the NiFi instance runs. However, sometimes the binding host
is different from the host that clients connect to. For example, when a NiFi
instance runs inside a Docker container, a client on a separate machine must
connect to the Docker host which forwards the connection to the container.
Kafka addresses this situation by allowing a broker to configure the host name
given out to producers, consumers, and other brokers to connect to. Implement
something similar in NiFi. Add a configuration property to specify the host
name to give out to clients to connect to a Remote Process Group Input Port. If
the property is not configured, then give out the name of host running the NiFi
instance.
