[ENH] Multi-stage docker-compose to package the app

[afzal442]

I went through your video tutorial. That was really great explaining DOCKERFILE and helm chart. But I stick to DOCKER COMPOSE here as I am already impressed and inspired through your tutorials. I have seen multi-stage dockerfile to support docker-compose where when any database like mysql is concerned, a special stage is defined. I have been very curious to see on how to create such stages and ship the app.

I can't wait to see you next up explaining on it.
