I have a bunch of DB backups used for QA and Integration Testing. From time to time, the schema of these DBs gets updated.
I thought of Building Images for each DB instance and commit changes after the schema gets updated, and this guide seems up to the job.
But thinking about updating the Postgres instance, I'd like a setup where I've data images "bound" to Postgres images, so I can update PG or the Data independently.
Something similar to submodules in git. Is there anything like that for docker?
