I have a Java Spring Boot application running in a container within a Kubernetes pod. I'm wondering if there's a way to:
Retrieve the Dockerfile configuration from the Kubernetes cluster namespace without pulling it from the repository.
Suppose my Java application runs with JAVA_OPTS=X. I would like Kubernetes to somehow add to the JAVA_OPTS so that it becomes JAVA_OPTS=X,Y,Z, and then restart the pod. Additionally, I want the new configuration to be saved inside the container without modifying the original Dockerfile.
