-------------------------------------
Summary: Expose bind port for Flink metric query service
Key: FLINK-16751
URL: https://issues.apache.org/jira/browse/FLINK-16751
Project: Flink
Issue Type: Improvement
Components: Runtime / Coordination
Affects Versions: 1.11.0
Reporter: Till Rohrmann
Fix For: 1.11.0
With FLINK-15911 it is now possible to run Flink behind a NAT/with an
unresolvable external address. However, due to FLINK-11127, the
{{MetricFetcherImpl}} tries to connect to the {{TaskManagers}} instead of the
other way around. If the TM is running behind a NAT, it would require to define
an external port. At the moment, it is only possible to configure the bind port
via {{metrics.internal.query-service.port}}.
I think in order to properly solve this problem we either solve FLINK-11127 or
we introduce a {{metrics.internal.query-service.bind-port}} option which allows
to configure a bind port. With such an option,
{{metrics.internal.query-service.port}} would become the external port.
