-To ensure you have the latest version of the collections, scenarios, parsers, etc., you can set the variable `DO_HUB_UPGRADE` to true.
-This will perform an update/upgrade of the hub every time the container is started.

-Be aware that if your container is misbehaving and caught in a restart loop, the CrowdSec hub may ban your IP for some time and your containers
-will run with the version of the hub that is cached in the container's image. If you enable `DO_HUB_UPGRADE`, do it when your infrastructure is running
-correctly and make sure you have some monitoring in place.
