If you are using bind mounts with your container, there is a really easy way to backup before an update.

  • stop the database container
  • cp -a bind_mount_dir/ bind_mount_dir.20231019

Then pull the latest database image and restart database container. If it works, yay, you're done.

If it doesn't work, reverse the steps:

  • stop the container
  • mv bind_mount_dir/ bind_mount_dir.broken
  • mv bind_mount_dir.20231019 bind_mount_dir

Restart container and you're back to exactly where you were before the upgrade.
