> Key: FLINK-26570
> URL: https://issues.apache.org/jira/browse/FLINK-26570
> Project: Flink
> Issue Type: Improvement
> Components: Stateful Functions
> Reporter: Fil Karnicki
> Assignee: Fil Karnicki
> Priority: Major
> Labels: pull-request-available

> Add the ability for users to provide placeholders in module.yaml, e.g.
> {code:java}
> kind: com.foo.bar/test
> spec:
> something: ${REPLACE_ME}
> transport:
> password: ${REPLACE_ME_WITH_A_SECRET}
> array:
> - ${REPLACE_ME}
> - sthElse {code}
> These placeholders would be resolved in
> org.apache.flink.statefun.flink.core.jsonmodule.RemoteModule#bindComponent
> using
> {code:java}
> ParameterTool.fromSystemProperties().mergeWith(ParameterTool.fromMap(globalConfiguration)
> {code}
> by traversing the ComponentJsonObject.specJsonNode() and replacing values
> that contain placeholders with values from the combined system+globalConfig
> map
