JKube Kit

Task description

Description

Currently, IngressEnricher simply returns when it discovers an Ingress resource already present.

https://github.com/eclipse/jkube/blob/bb9794e6a5ee4cf0a66b7e0b5e38feb35df9a711/jkube-kit/enricher/generic/src/main/java/org/eclipse/jkube/enricher/generic/IngressEnricher.java#L77-L80

While working on #1980 , we realized we might want to change this behavior.

I faced this issue yesterday while adapting the Apache Tomee quickstart (#1972). We might want to improve the IngressEnricher so that it can merge stuff for provided incomplete Ingress fragments.

Expected Behavior

IngressEnricher should check if provided Ingress fragment is valid and merge opinionated defaults if it's not complete. We should properly discuss these scenario and define what we expect.

Acceptance Criteria

• Needs to be discussed.
