Open Source Ruby Deployment Tools

Kamal offers zero-downtime deploys, rolling restarts, asset bridging, remote builds, accessory service management, and everything else you need to deploy and manage your web app in production with Docker. Originally built for Rails apps, Kamal will work with any type of web app that can be containerized. Kamal seeks to bring the advance in ergonomics pioneered by these commercial offerings to deploying web apps anywhere. Whether that’s low-cost cloud options without the managed-service markup from the likes of Digital Ocean, Hetzner, OVH, etc, or it’s your own colocated bare metal. To Kamal, it’s all the same. Feed the config file a list of IP addresses with vanilla Ubuntu servers that have seen no prep beyond an added SSH key, and you’ll be running in literally minutes.

A remote server automation and deployment tool written in Ruby. Capistrano extends the Rake DSL with methods specific to running commands on() servers. Capistrano is written in Ruby, but it can easily be used to deploy any language. If your language or framework has special deployment requirements, Capistrano can easily be extended to support them. Capistrano is bundled as a Ruby Gem. It requires Ruby 2.0 or newer. Capistrano can be installed as a standalone Gem, or bundled into your application. It is recommended to fix the version number when using Capistrano, and is therefore recommended to use an appropriate bundler. The capistrano-rails gem includes extras specifically designed for Ruby on Rails, specifically Asset Pipeline Support and Database Migration Support. Capistrano deploys using SSH. Thus, you must be able to SSH (ideally with keys and ssh-agent) from the deployment system to the destination system for Capistrano to work.

Easy git deployment is a lightweight deployment tool that simplifies the process of deploying applications to remote servers using Git as the primary mechanism. It works by setting up a remote repository with a post-receive hook that automatically updates the application whenever code is pushed. This approach allows developers to deploy applications by simply pushing changes to a designated branch, eliminating the need for complex deployment pipelines. The tool generates customizable deployment scripts that can perform tasks such as installing dependencies, running database migrations, and restarting services. It is designed to be easy to set up and integrate into existing workflows, making it accessible even for small teams or individual developers. Git Deploy also supports rollback functionality, allowing users to revert to previous versions if needed. Its hook-based architecture ensures that deployments are consistent and automated without requiring additional tooling.
