Chef Solo is very useful for single server configuration management.

Chef Solo config file '/etc/chef/solo.rb' is optional and it defaults to repo='/var/chef/'.

Just copy cookbooks directly to /var/chef/cookbooks. Run them using chef-solo command.

For e.g

cp -a /var/chef/cache/cookbooks /var/chef/cookbooks
