Code Deployment and Release Management with Rails

Code Deployment or Software Deployment and Release management with Ruby on Rails uses various tools such as Capistrano, Heroku, Mina, Vlad, Inploy etc. These automated tools are frameworks used to write and execute commands in parallel remote machines and thus ease the process of deployment and management of various applications.

Introduction

Deployment is a process of transferring your application onto a production server to make it available for other users. This process involves various activities and transitions between them. Though the general procedure remains same, the specific requirements vary with the software system.

Why Automation?

Deployment Automation tools

Capistrano

Capistrano is a Ruby program that gives you a set of advanced tools to deploy web applications to your servers. With Capistrano it’s also possible to deploy to many machines at once. Capistrano offers many advanced options and can be used to deploy many kinds of applications.

It supports the scripting and execution of arbitrary tasks, and includes a set of sane-default deployment workdflows.

Capistrano can be used to:

Reliably deploy web application to any number of machines simultaneously, in sequence or as a rolling set

  • To automate audits of any number of machines (checking login logs, enumerating uptimes, and/or applying security patches)
  • To script arbitrary workflows over SSH
  • To automate common tasks in software teams.
  • To drive infrastructure provisioning tools such as chef-solo, Ansible or similar.

Capistrano is also very scriptable, and can be integrated with any other Ruby software to form part of a larger too.

Heroku

Vlad

"Take some more [[tea]]," the March Hare said to Alice, very earnestly.

"I've had '''nothing''' yet," Alice replied in an offended tone, "so I can't take more."

"You mean you can't take ''less''?" said the Hatter. "It's very easy to take ''more'' than nothing." 		<p>"Take some more <a title="Tea" href="/wiki/Tea">tea</a>," the March Hare said to Alice, very earnestly.</p>
