Stefan Wang commented on FLINK-37893:
-------------------------------------
Could a committer assign FLINK-37893 to me? Have a PR ready —
https://github.com/apache/flink/pull/28047 — adds
kubernetes.rest-service.port-name (default "rest") so service-mesh
port-name policies can be honored without breaking existing deployments.
JobManager's REST service hardcodes the port name to "rest"
(Constants.REST_PORT_NAME). Service meshes that route by port name and
organizations with port-name conventions can't align Flink's rest
service with those policies. Adds kubernetes.rest-service.port-name
(default "rest") plumbed through KubernetesJobManagerParameters and
ServiceType#buildUpExternalRestService.
ServiceType#getRestPortFromExternalService
drops its name-filter — the rest Service always has exactly one port
so the lookup can return that port directly; works for any configured
name without plumbing it through the abstract getRestEndpoint.
Default preserves existing behavior; purely additive.

> Project: Flink
> Issue Type: Improvement
> Components: Deployment / Kubernetes
> Affects Versions: 1.16.1, 1.17.1, 1.18.1, 1.20.0, 1.19.1
> Reporter: Mayur Dhingra
> Priority: Major
> Labels: Kubernetes, pull-request-available, rest
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> While running Flink in Kubernetes mode, the Rest Service created by Flink
> framework has the REST_PORT_NAME is a fixed constant value called "rest".
> This should be made configurable by users via a configurable flink config.
> Many organization like ours have a strict policy of defining port names and
> current flink framework does not support it.
