------------------------------
Component/s: Runtime / Configuration
> Support env replacement in flink-kubernetes-operator CR
> -------------------------------------------------------
>
> Key: FLINK-27491
> URL: https://issues.apache.org/jira/browse/FLINK-27491
> Project: Flink
> Issue Type: Improvement
> Components: Kubernetes Operator, Runtime / Configuration
> Reporter: Yang Wang
> Priority: Major
>
> Flink deployment resources support env interpolation natively using $() syntax[1]. Users expected this to "just work" like other resources when using the operator, but it does not.
> It would be a great addition, simplifying job startup decision-making while following existing conventions.
