Working on a project which is a k8s service which is implemented using flask.

As part of the deployment, I'd like to run db migrations before the app starts execution.

I was wondering what is considered "best practice", and why.

Just mentioning here some of the ideas I had in mind:

• An entrypoint.sh script
• An init container
• A job
• A configmap

if you had other approach/technique, be my guest :)

Thanks in advance!
