Rudy - v0.9 BETA

Not your grandparents’ EC2 deployment tool.

Rudy is a development and deployment tool for EC2. It helps you build and maintain infrastructures by organizing them into groups of zones, environments, and roles. By making it quick and easy to build infrastructures, Rudy makes it feasible to run environments only for the time that you need them.

All configuration is organized into this hierarchy so you can define properties (machine image, machine type, IP address, etc…) by role, by environment, or by zone. You can also define routines for running shell commands and scripts, uploading files, creating disks and backups, etc… Routines are organized by hierarchy too so a "startup" routine can run one thing for your database machines and another thing for your application machines.

Rudy helps with other stuff too. Every machine can be given a hostname based on its zone, environment, role, and position (you can run multiple machines with the same role). These names look like this: m-us-east-1b-stage-app-01, but you can also assign your own names. Rudy also automatically creates a private keypair and security for each machine group (e.g. key-us-east-1b-stage-app and grp-us-east-1b-stage-app).

Get-Started with Rudy now.

Configuration

Rudy is configured via several Ruby-based domain specific languages.

Machines

The machines configuration describes the "physical" characteristics of your infrastructure.

    machines do
      env :stage do                   # Define an environment
        ami 'ami-e348af8a'            # Specify a machine image

        role :app do                  # Define a role
          addresses '11.22.33.44'     # Use elastic IPs

          disks do                    # Define EBS volumes
            path "/rudy/disk1" do
              size 100
              device "/dev/sdr"
            end
          end
        end

      end
    end

Routines

The routines configuration describes repeatable processes that you can execute on your machines.

    routines do

      startup do                      # $ rudy startup
        adduser :rudy
        authorize :rudy               # Enable passwordless login

        disks do
          create "/rudy/disk1"        # Create, format, and mount a volume
        end

        remote :rudy do               # Run remote commands via SSH
          mkdir :p, "great"           # $ mkdir -p great
          mysql_init :start
          your_script 'arg1', 'arg2'  # Call your own scripts
        end
      end

    end

See Rudyfile for a complete configuration example.

Running Commands

Rudy comes with a command-line tool called rudy. It provides commands for describing the infrastructures you’ve built with Rudy.

    $ rudy machines
    m-us-east-1d-stage-app-01: ec2-67-202-0-112.compute-1.amazonaws.com
    m-us-east-1d-stage-app-02: ec2-174-129-117-30.compute-1.amazonaws.com

    $ rudy disks
    disk-us-east-1d-stage-app-01-rudy-disk1
    disk-us-east-1d-stage-app-02-rudy-disk1

    $ rudy backups
    back-us-east-1d-stage-app-01-rudy-disk1-20090803-1857-49
    back-us-east-1d-stage-app-01-rudy-disk1-20090803-1858-36
    back-us-east-1d-stage-app-02-rudy-disk1-20090803-1911-05

See rudy -h for more info.

Project Status

This is a BETA release. That means Rudy is not ready for production use! See Project-Status.

Installation

Via Rubygems:

    $ sudo gem install rudy

or via download:
