Breakpoints not hit in Java app deployed to GKE #3010

Closed nicopoirier closed 3 years ago

nicopoirier commented 3 years ago

I'm trying to debug java-hello-world from here with docker.io. The project is build and deploy, the url is ok and the application is running, the panel Debug is launch but the panel Debug(5005) is never launch and no portForward to the 5005. I can't debug the application

Skaffold.yaml
