[chef] Re: Variables in attributes file

[Carlton Stedman < >]

Set up a ruby_block in a recipe with a node.set, like so:

ruby_block "do something" do
  block do
    bar, baz = # something
    node.set["foo"][bar] = baz
    node.save # only if chef-zero/chef-client
  end
end

That block can subscribe or be notified by other resources. Not sure if it works, at all, with chef solo, but give chef zero a try.

Is it possible to create attributes based on a dynamic variables?

# Example

default['ipdns']['#{int}']['address'] = '#{ip}'

# Code

node['network']["interfaces"].each do | int, parms |

    File.open("/etc/sysconfig/network-scripts/ifcfg-#{int}") do |f|

      f.each_line do |line|

        if line.strip == ">

          node['network']["interfaces"]["#{int}"]["addresses"].each do |ip, params|

            if params['family'] == ('inet')

              #puts "#{int} - #{ip}"

              default['ipdns']['#{int}']['address'] = '#{ip}'

              #puts { "int" => "{int}", "ip" => "{ip}" }
