---------------------------------
Summary: 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
Reporter: Yang Wang
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.
