Rudy - v0.8 BETA

Not your grandparents’ EC2 deployment tool.

Rudy is a command-line development and deployment tool for Amazon Web Services. It helps you build and manage machines in EC2 by organizing them into groups of environments and roles. These are called machine groups. stage is the default environment and app is the default role. You can run multiple machines with the same role. These are called positions. Rudy also supports running machine groups across availability zones.

When you put all this together, you have a unique name for every machine. The default machine is:

             zone     env  role
              v        v    v
        m-us-east-1b-stage-app-01
        ^                       ^
     "machine"                position

All configuration is organized into the zones, environments, and roles that you specify (Rudy assumes positions are identical which is important for backups and scaling). And as you’d expect, the defaults can be changed too (in ~/.rudy/config).

See Getting-Started for more info.

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

Configuration

Machines

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

    env :stage do         # Define an environment
      ami 'ami-e348af8a'

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

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

Routines

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

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

      disks do                   # Create a disk
        restore "/rudy/disk1"    # from a backup
      end

      after :rudy do      # Run remote SSH commands
        mkdir :p, "great"        # $ mkdir -p great
        touch "great/scott"      # $ touch great/scott
        ls :l, :a                # $ ls -l -a
      end
    end
