capistrano-rightscale

Capistrano plugin for associating Rightscale tags with roles.

Introduction

RightScale provides a service for managing deployments of servers in various clouds. Servers can be tagged with machine tags. This plugin allows for specific tags in specific deployments to be mapped to Capistrano roles.

At present these mappings require several api calls, which are slow. On the first call, a cache file is written in the users home directory. This can be disabled with an ENV variable RIGHTSCALE_CACHE=false.

Installation

capistrano-rightscale is provided as a Ruby gem, with the following dependencies:

Capistrano >= 2.1.0
Rightscale API

Usage

In order to use the capistrano-rightscale plugin, you must require it in your Capfile:

require 'capistrano/rightscale'

Then you must specify your Rightscale API credentials:

set :rightscale_username, '???'
set :rightscale_password, '???'
set :rightscale_account, 12345

In order to define your roles, you defined the equivelent machine tags and deployment mappings:

tag :webserver, "x99:role=app", :deployment => 45678
