dingguotao opened a new pull request, #29519: URL: https://github.com/apache/flink/pull/29519
## What is the purpose of the change Add a config option to control `enableServiceLinks` of the JobManager and TaskManager pods. With many Flink clusters in one namespace, the Service environment variables injected by Kubernetes slow down the pod startup. See FLINK-41025. ## Brief change log - Add `kubernetes.pod.service-links.enabled` (Boolean, no default value). - `InitJobManagerDecorator` / `InitTaskManagerDecorator` overwrite `enableServiceLinks` of the pod spec only when the option is configured; otherwise the pod template value or the Kubernetes default applies. - Document the option and add `enableServiceLinks` to the "Fields Overwritten by Flink" table (en/zh). ## Verifying this change - `InitJobManagerDecoratorTest` / `InitTaskManagerDecoratorTest`: the field is not set by default, and is set when the option is configured. - `DecoratorWithPodTemplateTestBase`: the value from the pod template is kept, and is overwritten when the option is configured. ## Does this pull request potentially affect one of the following parts - Dependencies: no - The public API: no - The serializers: no - The runtime per-record code paths: no - Anything that affects deployment or recovery: yes (Kubernetes pod spec, only when the option is configured) - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? yes - If yes, how is the feature documented? docs -- This is an automated message from the Apache Git Service.
