ASF GitHub Bot updated SPARK-58203:
-----------------------------------
Labels: pull-request-available (was: )
> Support configuring spark-managed UI service to work with spark.ui.port=0
> -------------------------------------------------------------------------
>
> Key: SPARK-58203
> URL: https://issues.apache.org/jira/browse/SPARK-58203
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes
> Affects Versions: 4.3.0
> Reporter: Chenyu Zheng
> Priority: Major
> Labels: pull-request-available
>
> In hostNetwork mode, setting {{spark.ui.port=0}} (kernel-picked random port)
> is required to avoid UI port collisions when multiple drivers share the
> host's port space.
> Today the driver UI Service is created by spark-operator, not by Spark
> itself. spark-operator has no way to know the actual UI port that the
> driver's UI server ends up binding to.
> Proposal: provide configs to let Spark create and manage the UI Service
> itself.
> * Add config {{spark.kubernetes.driver.ui.service.enabled}} (default false).
> When enabled, Spark creates a dedicated ClusterIP UI Service.
> * After the driver's Web UI binds, Spark patches the Service's
> {{targetPort}} to the actual bound port.
