For small number of servers and push deployment, I show how to run LittleChef here:
Using RVM for Ruby needed for Chef’s knife later.
ubuntu@testbox:~/littlechef$ rvm use 1.9.2
Using virtrualenv for Python, so as not to clutter environment’s Python installation.
Genenerate metadata.json for Chef recipes.
ubuntu@testbox:~/littlechef$ workon lchef ubuntu@testbox:~/littlechef$ cd kitchen/cookbooks (lchef)ubuntu@testbox:~/littlechef/kitchen/cookbooks$ knife cookbook metadata -a -o ./ Generating metadata for alestic_ppa from /home/ubuntu/littlechef/kitchen/cookbooks/alestic_ppa/metadata.rb Generating metadata for apt from /home/ubuntu/littlechef/kitchen/cookbooks/apt/metadata.rb Generating metadata for graylog2 from /home/ubuntu/littlechef/kitchen/cookbooks/graylog2/metadata.rb Generating metadata for java from /home/ubuntu/littlechef/kitchen/cookbooks/java/metadata.rb Generating metadata for java_sun from /home/ubuntu/littlechef/kitchen/cookbooks/java_sun/metadata.rb Generating metadata for logrotate from /home/ubuntu/littlechef/kitchen/cookbooks/logrotate/metadata.rb Generating metadata for mdadm from /home/ubuntu/littlechef/kitchen/cookbooks/mdadm/metadata.rb Generating metadata for memcached from /home/ubuntu/littlechef/kitchen/cookbooks/memcached/metadata.rb Generating metadata for mongodb from /home/ubuntu/littlechef/kitchen/cookbooks/mongodb/metadata.rb Generating metadata for mongodbx from /home/ubuntu/littlechef/kitchen/cookbooks/mongodbx/metadata.rb Generating metadata for nginx from /home/ubuntu/littlechef/kitchen/cookbooks/nginx/metadata.rb Generating metadata for quick_start from /home/ubuntu/littlechef/kitchen/cookbooks/quick_start/metadata.rb Generating metadata for runit from /home/ubuntu/littlechef/kitchen/cookbooks/runit/metadata.rb Generating metadata for xfs from /home/ubuntu/littlechef/kitchen/cookbooks/xfs/metadata.rb
List nodes using LittleChef:
(lchef)ubuntu@testbox:~/littlechef/$ fix list_nodes
ec2-xx-xx-xxx-xxx.compute-1.amazonaws.com
Roles:
Recipes: alestic_ppa
Node attributes:
server2
Roles:
Recipes: mdadm, memcached
Node attributes:
mdadm: {'DEVICE': '/dev/sdj'}
memcached: {'memory': '512'}
List of files on my kichen directory:
(lchef)ubuntu@testbox:~/littlechef/kitchen$ ls auth.cfg cookbooks data_bags nodes roles site-cookbooks (lchef)ubuntu@testbox:~/littlechef/kitchen$ ls cookbooks/ alestic_ppa apt graylog2 java java_sun logrotate mdadm memcached mongodb mongodbx nginx quick_start README runit xfs
Ok, let’s run the nginx installation using LittleChef to lucid32 server.
For simplicity, /etc/hosts file contains the IP mapping of lucid32 server.
(lchef)ubuntu@testbox:~/littlechef/kitchen$ fix node:lucid32 recipe:nginx == Applying recipe 'nginx' on node lucid32 == Saving node configuration to nodes/lucid32.json... Synchronizing node, cookbooks, roles and data bags... ubuntu@lucid32's password: Cooking...

Disconnecting from lucid32... done.
Now to check for the running Nginx server:
(lchef)ubuntu@testbox:~/littlechef/kitchen$ fix node:lucid32 ssh:"sudo netstat -lp | grep nginx " Executing the command 'sudo netstat -lp | grep nginx ' on the node lucid32... tcp 0 0 *:www *:* LISTEN 814/nginx Done. Disconnecting from lucid32... done.
