Add a downgrade command, so you can reverse the upgrade process and go back to Kamal 1.9. This replaces kamal-proxy and reboots all the accessories. This gives an upgrade and downgrade path: Upgrade: 1. Upgrade config to be Kamal 2 compatible + use kamal 2.0 2. Run `kamal upgrade` Downgrade: 1. Switch back to previous config + use kamal 1.9 2. Run `kamal downgrade` You can set `--rolling` to downgrade one host at a time.
Kamal: Deploy web apps anywhere
From bare metal to cloud VMs, deploy web apps anywhere with zero downtime. Kamal has the dynamic reverse-proxy Traefik hold requests while a new app container is started and the old one is stopped. 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.
