The method described is a valid one but not the easiest to maintain.

The values you're looking for can be obtained from the Chef::Config hash i.e.:

chef > Chef::Config[:chef_server_url]

 => "http://10.1.1.83:4000"

Note that the information is not available in the format exactly you're asking for. Another thing is you have a bit of a chicken and egg problem. How are you able to run chef connected to the server if you don't have the DNS entry already? Is this just a failback for flakey DNS?

One way is to set the values in your client node.

Do a knife node edit and add the values chefserverip and chefserverhostname.

These will be accessible to all recipes.

You can also set recipe specific attributes.

For example i have a recipe:

# Creating true /etc/hosts
template "/etc/hosts" do
    mode 0644
    owner "root"
    group "root"
    source "etc/hosts.erb"
    variables ({
                :ip => node[:dc][:ip],
                :domain => node[:dns][:domain],
                :hostname => node[:dc][:hostname],
                :chefserverip => ???????????????,
                :chefserverhostname => ???????????????
                })
    action :create
end


and template:

127.0.0.1           localhost
<%= @chefserverip %>           <%= @chefserverhostname %>.<%= @domain %>
<%= @ip %>        <%= @hostname %>.<%= @domain %> <%= @hostname %>
# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

How I can access service variables ??????????????? and ???????????????

And for a future:

How can i know what service vars are present when recipes are run? My be present a simple method or you hac a true doc url ?

Thank you very much.

This is not true way. I think this vars must be present by default in chef runtime.

Set vars in node, environment, data bag, etc - is not true.
