App won't start in OpenShift due to incorrect JAVA_APP_JAR with quarkus-kubernetes-config

[michalvavrik]

Describe the bug

Quarkus app won't start in OpenShift as there is JAVA_APP_JAR set to ~ artifact-id-version-runner.jar and no CMD set. In Quarkus 2.12.2.Final there was also set /deployments/artifact-id-version-runner.jar (so not a new behavior), however that was not used as there was cmd that started the app

    Command:
      java
      -jar
      /deployments/quarkus-run.jar

It's consequence of https://github.com/quarkusio/quarkus/pull/27733, differs from https://github.com/quarkusio/quarkus/issues/28037 in that I added single dependency quarkus-kubernetes-config.

Expected behavior

App should start just fine, e.g. it could set JAVA_APP_JAR to /deployments/quarkus-run.jar or set cmd. Example of generated openshift.yml with reproducer when k8 config dep is removed: https://github.com/michalvavrik/openshift-quickstart/blob/master/without-troublesome-dep-openshift.yml

Actual behavior

Example of generated openshift.yml with reproducer: https://github.com/michalvavrik/openshift-quickstart/blob/master/troublesome-openshift.yml App POD in CrashLoopBackOff and exception is logged:

Starting the Java application using /opt/jboss/container/java/run/run-java.sh ...

1. OC stuff

Steps to reproduce the behavior:

1. git clone https://github.com/michalvavrik/openshift-quickstart.git
2. cd openshift-quickstart
3. quarkus build
4. inspect pod

Alternative reproducer: Quarkus QE test suite module contains failing test, clone it, and run mvn clean verify -f config/ -Dit.test=OpenShiftApiServerConfigSecretConfigIT -Dopenshift

Additional information

I think JAVA_APP_JAR that is set through AddEnvVarDecorator is overwritten in Dekorate (just suggestion...).

[geoand]

Isn't this similar to one you had reported a few days ago?

[michalvavrik]

@geoand very similar, but that one is fixed. This one, I believe, is due to Dekorate overwriting the env. variable JAVA_APP_JAR. This is not a new behavior as this issue was already in Quarkus 2.12 etc. it's just now we don't have a CMD se the variable is actually used.

Please mention that the issue I opened a few days ago is fixed and arguably in desirable fashion. Had Dekorate respected the variable we set in Quarkus, it would also fix this one - but that's my opinion, please ask @Sgitario and @iocanel .

[michalvavrik]

I didn't know about this scenario, that's why I created new issue now.

[geoand]

Makes sense, I just wanted to clarify.
