Any state that a container uses, such as databases or static assets, should be mapped to something outside k8s, no? I thought container orchestration was only for app later

we are talking in a context where you would spin up a new cluster whenever you want to upgrade kubernetes version.

In that case you don't want to migrate application/user data so you are kind of forced to keep DBs and filesystems outside.
