First, build the jar executable using maven
$ mvn verifyThis should create a jar file in the target directory.
Now, we can build our image using podman
$ podman build -t jaft .The building phase is done. Now we can run it. To make our life easier, we're running all our instance in the same pod (this makes the networking easier in dev/test phase)
$ podman pod create -p 8080-8082:8080-8082
$ podman pod ps
