How I can capture values in command line and add to recipe?

Question

I am new to Chef and Ruby

I need to pass two variables to Chef on the command line and have those variables available in a recipe.

How I can capture these va

Answer 1

You can set variables inside recipes by calling commands

nodename = `cat /etc/chef/client.rb | grep "node_name" | sed -e 's/\//g' | sed '/^$/d;s/[[:blank:]]//g' | sed 's/\"//g'`

And then use the variable for other chef blocks

execute "echo nodename for node #{nodename}"
 command "echo #{nodename}"
 action :run
 only_if {nodename == "node1"}
end

This will get the node.name attribute from the client.rb file without asking for it to the chef server.
