Why use this?

Kamal simplifies deployment by treating any SSH-accessible Linux server as a deployment target. It packages applications as Docker images, manages releases, configures a reverse proxy, and supports zero-downtime rollouts and rollbacks.

It is a good fit for teams that want cloud-portable deployments without adopting a full managed PaaS. Kamal is especially popular in the Ruby and Rails ecosystem but works with other web applications packaged in Docker.

Key Features

• Docker-based deployment to any server
• Zero-downtime deploys and instant rollbacks
• Built-in reverse proxy and SSL management
• Simple YAML configuration
