FEATURE REQUEST: Config option to call a webhook after VPN is established

[codersaur]

Use Case: I'm using wireguard-initramfs as part of my fully-LUKS-encrypted remote backup server. Occasionally the server will reboot outside of my control and I want to receive a notification when the remote server has booted to initramfs and is waiting to be unlocked.

I am thinking a simple solution would be to add support for another wget request to be made once the wireguard tunnel has been successfully established. By hosting a webhook endpoint on the other end of the VPN, this call could trigger any number of custom actions such as emailing me.

Thanks for the suggestion. I am thinking of other use cases where this would be useful. I would like to keep the role small and focused; but something like this does make sense. Just want to make sure that whatever is decided is well thought out and useful for other cases that may occur.
