Attributes

See attributes/default.rb for default values.

• node['resolver']['search'] - an array of search domains for host-name lookup; a string may also be provided for backwards compatibility. Limited to 6 elements and 256 characters.
• node['resolver']['nameservers'] - Required, an array of nameserver IP address strings; the default is an empty array, and the default recipe will not change resolv.conf if this is not set. See Usage.
• node['resolver']['options'] - a hash of resolv.conf options. See Usage for examples.
• node['resolver']['domain'] - Local domain name. if nil, the domain is determined from the local hostname returned by gethostname(2).

Recipes

default

Configure /etc/resolv.conf based on attributes.

Usage

Using the default recipe, set the resolver attributes in a role, for example from my base.rb:

"resolver" => {
  "nameservers" => ["10.13.37.120", "10.13.37.40"],
  "search" => [ "int.example.org", "ext.example.org" ],
  "options" => {
    "timeout" => 2, "rotate" => nil
  }
}

The resulting /etc/resolv.conf will look like:

search int.example.org ext.example.org
nameserver 10.13.37.120
nameserver 10.13.37.40
options timeout:2 rotate
