[Discussion] Devs and Devops: if you have running containers in production, how are you upgrading those containers? (lemdit.com)

Hey all!

I'm seeking guidance. I have a lot of apps that use ORMs like Mongoose or Sequelize or Sqlalchemy, or even just init-db scripts with raw SQL. Point is a lot of apps have changes to the data layer. When we program and make apps they tend to describe how they need to see a database. Sometimes its no trivial feat to do an upgrade - and even if you have a CI/CD pipeline in place what does that look like to have something like even lemmy upgrade in a container.

If you have these apps in production how are you handling these apps? Both developer perspective and devops welcomed.

I see the devs offering insight into maybe how the backend recognizes database state, while the devops perhaps either describing process and implementation.

This also assumes you have adequate testing capabilities which are important so that you can evaluate unit capabilities, integrated capabilities, and performance characteristics.

On cloud you might have your testing infra be ephemeral and spin up whenever you need to perform the testing (as well as your IAC capabilities).

But this would partially evaluate any issues with the app coordinating with the database.

I would also assume DBA's can write some test scripts to execute as well.
