Hooks: pre-proxy-reboot
Run before rebooting the kamal-proxy container, when you call kamal proxy reboot
.
If you have the hook disable the current server in an external load balancer and use the –rolling flag, you can use this for a zero-downtime proxy reboot.
With a rolling reboot hook will be called once for each server, with KAMAL_HOSTS
containing the current server. With a non-rolling reboot it will be called just once.
Use the post-proxy-reboot hook to re-enable the server.
