Plan Docker Compose updates and rollbacks before the first change

An update plan is a recovery plan with a smaller time window and a clearer definition of success.

Record the deployed state

Keep the rendered Compose configuration, image versions, environment references, and the state backup associated with the current deployment. This gives an update a known point to return to.

Change one meaningful layer at a time

Avoid combining host changes, proxy changes, database migrations, and application upgrades in one unreviewed operation. Keep the operation small enough that a failed check identifies the layer that changed.

Verify the restored service, not only the container

After an update or rollback, test the user-facing service and the state it depends on. A running container does not prove that data, jobs, routes, or credentials are correct.
