-------------------------------------------
Summary: Provide a way to populate Initial Node Identities for
containered envirronment
Key: NIFI-12523
URL: https://issues.apache.org/jira/browse/NIFI-12523
Project: Apache NiFi
Issue Type: Improvement
Components: Configuration
Reporter: Dominique Jean-Prost
Currently, when running in a container environment (docker for instance) there
is no way to provide values to populate Initial Node Identity which is expected
in {{authorizers.xml}}
cf
[https://nifi.apache.org/docs/nifi-docs/html/administration-guide.html#cluster-node-identities]
The startup scripts of nifi in a docker environment only take care for the
moment of {{Initial Admin Identity}}, but not {{Initial Node Identity}}, cf
[https://nifi.apache.org/docs/nifi-docs/html/administration-guide.html#cluster-node-identities]
Instead of using a single value for {{NODE_IDENTITY}}, it should be used a
values list like {{INITIAL_NODE_IDENTITIES}}, and iterate thought the list and
add as much entries in the file.
We could be inspired by
