[Podman] How to build image for own jar file

Hello, I have successfully build docker image "sapmachine", a build of OpenJDK. Now I want to build my own image to run my own jar file. This jar file is located in ~/.mpw-gui/masterpassword-gui.jar, and with locally installed OpenJDK I would run this command: java -jar .mpw-gui/masterpassword-gui.jar Could you please advise how to build my own image for this java application?
