------------------------------------
Summary: Remote module configuration interpolation
Key: FLINK-26570
URL: https://issues.apache.org/jira/browse/FLINK-26570
Project: Flink
Issue Type: Improvement
Components: Stateful Functions
Reporter: Fil Karnicki
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
