Usage

With CloudFormation, use the folowing in Mappings:

"Mappings": {
    "UserData": {
        "CloudInit": {
        "BaseInclude": "http://public.fewbytes.com/bootstrap/latest/ubuntu-chef-base.yaml"
        }
    },
    "Config": {
        "Chef": {
            "serverURL": "https://chef.server.url.com:444",
            "validationCert": "-----BEGIN RSA PRIVATE KEY-----\n-----END RSA PRIVATE KEY-----"
        },
        "Misc": {
            "domain": "fewbytes.info"
        }
    }
}

Then in your Instance resource (or AutoScalingLaunchConfig) use the following:

    "UserData": {"Fn::Base64": {"Fn::Join": ["\n", [
      "#include-once",
      {"Fn::FindInMap": ["UserData", "CloudInit", "BaseInclude"]}
      ] ]
    }},

And in metadata use:

  "Metadata": {
    "chef": {
      "role": "storm_nimbus",
      "run_list": ["role[storm_nimbus]", "recipe[cloudformation::signal]"],
      "serverURL": {"Fn::FindInMap":["Config", "Chef", "serverURL"]},
      "validationCert": {"Fn::FindInMap":["Config", "Chef", "validationCert"]},
      "environment": {"Ref": "Environment"}
    },
    "generic": {
      "domain": {"Fn::FindInMap": ["Config", "Misc", "domain"]}
    }
  },

Note: For AutoscalingGroups put the metadata in the AutoScalingGroup resource and not the AutoScalingLaunchConfig. UserData goes in LaunchConfig, Metadata in AutoScalingGroup.
