Dockerfiles

For existing applications, you have two Dockerfiles:

    Dockerfile.jvm: this is the one for the legacy-jar packaging
    Dockerfile.fast-jar: this is the one for fast-jar packaging (so the new default)

For newly generated applications, the situation is a bit different:

    Dockerfile.jvm: this is the one for the fast-jar packaging (so the new default)
    Dockerfile.legacy-jar: this is the one for legacy-jar

Note that if you want all your applications to be consistent, you can just update the Dockerfiles of your existing applications with the ones of a newly generated project.
