Answer 1

At this point I am just assuming you have:

• a Dockerfile
• a JAR <-- that you modify
• a docker-compose.yaml file

You ran once docker-compose up -d to start and build your service. You need to run docker-compose up -d --build for any subsequent changes to your JAR or Dockerfile otherwise docker-compose will just use the already built image. You can check that with docker image ls
