SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Kamal enables zero-downtime deployments for containerized applications by orchestrating deploys with SSH, Docker, and Kamal Proxy, while handling environments, accessories, and rollbacks.

Core Features & Use Cases

  • Standard deploy workflow with zero-downtime transitions.
  • Multi-environment support (staging, production) and rollback capabilities.
  • Accessories management (databases, Redis) and health checks.

Quick Start

Install Kamal, run kamal init, configure deploy.yml, and use kamal deploy to perform a zero-downtime release.

FAQPage Schema
How do I perform zero-downtime deployments with Docker and SSH?▼

Zero-downtime deployments orchestrate container transitions across remote servers using SSH and Kamal Proxy for traffic routing. Kamal automates this by coordinating Docker image builds, pushing to registries, and swapping running containers while maintaining service availability throughout the process.

What is Kamal and how does it work for containerized applications?▼

Kamal is a deployment orchestrator that manages containerized web applications on remote Linux servers via SSH. It handles Docker image deployment, Kamal Proxy traffic routing, multi-environment configuration, and rollback capabilities to enable seamless production releases.

How do I set up Kamal for deploying across multiple environments?▼

Configure deploy.yml with environment-specific settings for staging and production, define Docker registry credentials, specify remote server SSH access, and use Kamal commands to deploy, manage accessories like databases and Redis, and rollback if needed across all environments.

Can I use Kamal to manage databases and Redis as part of deployments?▼

Yes, Kamal manages accessories including databases and Redis alongside application containers. Define them in deploy.yml to coordinate their deployment, health checks, and lifecycle with your main containerized application across remote servers.

What happens if a Kamal deployment fails, and can I roll back?▼

Kamal tracks deployment state and provides rollback capabilities to revert to a previous release if deployment fails or issues arise. Use built-in rollback workflows to restore service stability without manual intervention on remote servers.

Do I need SSH access to use Kamal for deployments?▼

Yes, Kamal requires SSH access to remote Linux servers to execute deployment commands, manage Docker containers, and coordinate health checks. SSH is the primary transport for all orchestration operations Kamal performs.
