Recipes

default

Installs the dnsmasq package. Depending on the [:dnsmasq][:enable_dns] and [:dnsmasq][:enable_dhcp] attributes it includes the dns and dhcp recipes respectively.

dhcp

Includes the default recipe and writes the contents of the node[:dnsmasq][:dhcp] attribute hash to /etc/dnsmasq.d/dhcp.conf. Here is an example of the necessary attributes for DHCP with TFTP enabled:

'dnsmasq' => {
  'enable_dhcp' => true,
  'dhcp' => {
    'dhcp-authoritative' => nil,
    'dhcp-range' => 'eth0,10.0.0.10,10.0.0.100,12h',
    'dhcp-option' => '3', #turns off everything except basic DHCP
    'domain' => 'lab.atx',
    'interface' => 'eth0',
    'dhcp-boot' => 'pxelinux.0',
    'enable-tftp' => nil,
    'tftp-root' => '/var/lib/tftpboot',
    'tftp-secure' => nil
  }
}

dns

Includes the default and manage_hostsfile recipes, then writes the content of the node[:dnsmasq][:dns] attribute hash to /etc/dnsmasq.d/dns.conf.

manage_hostsfile

Loads the dnsmasq data bag managed_hosts item and merges it with any nodes in the [:dnsmasq][:managed_hosts] attribute, then writes them out to /etc/hosts/ via the hosts_file cookbook.

Usage

Data Bag

If you need manage your DNS hosts you may use the dnsmasq data bag managed_hosts item. It takes the form:

{
    "id": "managed_hosts",
    "maps": {
      "192.168.0.100": "www.google.com",
      "192.168.0.101": ["www.yahoo.com", "www.altavista.com"]
    }
}

  • [:dnsmasq][:enable_dhcp] whether to enabled the DHCP service, default is false
  • [:dnsmasq][:managed_hosts] hash of IPs and hostname/array of hostnames for the manage_hostfile recipe, default is empty
  • [:dnsmasq][:managed_hosts_bag] name of the data bag item, default is managed_hosts
