Chef: add node attributes automatically

Using knife exec

The best way probably

knife exec -E "nodes.find(:name => 'chef-node') { |node|  node.normal_attrs['some_key'] = 'some_value'; node.save; }"

Using gem

Unofficial gem: https://github.com/pdf/knife-attribute

Using $EDITOR with script

• Create a script editor.rb:

       #!/usr/bin/env ruby
       require 'json'

       data = JSON.parse(File.read(ARGV[0]))

       # You can read data from other json file on disk and
       # add key=value as attribute
       data['normal']['some_key'] = 'some_data'

       File.write(ARGV[0], JSON.pretty_generate(data))

• Set the $EDITOR variable : export EDITOR=./path/to/editor.rb

• Run knife command: knife node edit chef-node
