It is possible to add pre- and post-update-hooks to the
update.sh script that upgrades your whole mailcow installation.
To do so, just add the corresponding bash script into your mailcow root directory:
pre_update_hook.shfor commands that should run before the update
post_update_hook.shfor commands that should run after the update is completed
Keep in mind that
pre_update_hook.sh runs every time you call
post_update_hook.sh will only run if the update was successful and the script doesn't have to be re-run.
The scripts will be run by bash, an interpreter (e.g.
#!/bin/bash) as well as an execute permission flag ("+x") are not required.
