Kamal: Deploy web apps anywhere

From bare metal to cloud VMs using Docker, deploy web apps anywhere with zero downtime. Kamal uses the dynamic reverse-proxy Traefik to hold requests, while the new app container is started and the old one is stopped — working 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.
