For easy updates from Traefik to kamal-proxy, add `kamal proxy update`. This stops and removes Traefik and kamal-proxy containers (just in case it is run after an update). Then it starts kamal-proxy and calls `kamal-proxy deploy` to route to any app containers that are already running. It can be run with a rolling option and calls the `pre-proxy-reboot` and `post-proxy-reboot` hooks for each host.
Kamal: Deploy web apps anywhere
From bare metal to cloud VMs, deploy web apps anywhere with zero downtime. Kamal uses a custom proxy for zero-downtime deployments. Works seamlessly across multiple hosts, using SSHKit to execute commands. Originally built for Rails apps, Kamal will work with any type of web app that can be containerized with Docker.
➡️ See kamal-deploy.org for documentation on installation, configuration, and commands.
