Chefdore

Chef tool that was named after Dumbledore.

I created this gem in order to help those who may want to convert Chef Roles to Chef Cookbooks.

Installation

$ gem install chefdore

Usage

Let's say you have a Chef Role in your Chef Server and you want to convert it to a Chef Cookbook.

First let's take a look at an "example_role":

$ knife role show example_role --format json
{
  "name": "example_role",
  "description": "Chef-server example role",
  "json_class": "Chef::Role",
  "default_attributes": {
    "ntp": {
      "servers": [
        "0.pool.ntp.org",
        "1.pool.ntp.org",
        "2.pool.ntp.org",
        "3.pool.ntp.org"
      ]
    }
  },
  "override_attributes": {
    "developer_mode": false,
    "monitoring": {
      "metric_provider": "collectd",
      "procmon_provider": "monit"
    },
    "glance": {
      "image_upload": true,
      "images": [
        "cirros",
        "precise"
      ]
    },
    "nova": {
      "ratelimit": {
        "api": {
          "enabled": true
        },
        "volume": {
          "enabled": true
        }
      },
      "libvirt": {
        "virt_type": "qemu"
      },
      "networks": {
        "public": {
          "label": "public",
          "ipv4_cidr": "10.10.100.0/24",
          "bridge": "br100",
          "bridge_dev": "eth0.100",
          "dns1": "8.8.8.8",
          "dns2": "8.8.4.4"
        },
        "private": {
          "label": "private",
          "ipv4_cidr": "172.16.101.0/24",
          "bridge": "br101",
          "bridge_dev": "eth0.101",
          "dns1": "8.8.8.8",
          "dns2": "8.8.4.4"
        }
      }
    },
    "mysql": {
      "allow_remote_root": true,
      "root_network_acl": "%"
    },
    "osops_networks": {
      "nova": "192.168.1.0/24",
      "public": "192.168.1.0/24",
      "management": "192.168.1.0/24"
    },
    "package_component": "folsom"
  },
  "chef_type": "role",
  "run_list": [
    "recipe[osops-utils::packages]",
    "recipe[osops-utils::nf_conntrack_max]",
    "recipe[osops-utils::vhost_net]",
    "recipe[openssh]",
    "recipe[ntp]",
    "recipe[rsyslog::default]",
    "recipe[hardware]",
    "recipe[osops-utils::version]"
  ],
  "env_run_lists": {

  }
}

All we have to do is pipe that output into our little command line client:

$ knife role show example_role --format json | chefdore convert
default["ntp"]["servers"] = ["0.pool.ntp.org", "1.pool.ntp.org", "2.pool.ntp.org", "3.pool.ntp.org"]
override["developer_mode"] = false
override["monitoring"]["metric_provider"] = "collectd"
override["monitoring"]["procmon_provider"] = "monit"
override["glance"]["image_upload"] = true
override["glance"]["images"] = ["cirros", "precise"]
override["nova"]["ratelimit"]["api"]["enabled"] = true
override["nova"]["ratelimit"]["volume"]["enabled"] = true
override["nova"]["libvirt"]["virt_type"] = "qemu"
override["nova"]["networks"]["public"]["label"] = "public"
override["nova"]["networks"]["public"]["ipv4_cidr"] = "10.10.100.0/24"
override["nova"]["networks"]["public"]["bridge"] = "br100"
override["nova"]["networks"]["public"]["bridge_dev"] = "eth0.100"
override["nova"]["networks"]["public"]["dns1"] = "8.8.8.8"
override["nova"]["networks"]["public"]["dns2"] = "8.8.4.4"
override["nova"]["networks"]["private"]["label"] = "private"
override["nova"]["networks"]["private"]["ipv4_cidr"] = "172.16.101.0/24"
override["nova"]["networks"]["private"]["bridge"] = "br101"
override["nova"]["networks"]["private"]["bridge_dev"] = "eth0.101"
override["nova"]["networks"]["private"]["dns1"] = "8.8.8.8"
override["nova"]["networks"]["private"]["dns2"] = "8.8.4.4"
override["mysql"]["allow_remote_root"] = true
override["mysql"]["root_network_acl"] = "%"
override["osops_networks"]["nova"] = "192.168.1.0/24"
override["osops_networks"]["public"] = "192.168.1.0/24"
override["osops_networks"]["management"] = "192.168.1.0/24"
override["package_component"] = "folsom"
include_recipe "osops-utils::packages"
include_recipe "osops-utils::nf_conntrack_max"
include_recipe "osops-utils::vhost_net"
include_recipe "openssh"
include_recipe "ntp"
include_recipe "rsyslog::default"
include_recipe "hardware"
include_recipe "osops-utils::version"

It outputs exactly what should be dropped into your new Chef Cookbook attributes file. e.g. attributes/default.rb
