Some scripts that actually have some real world application.
Uses the knife search command to generate a csv file of the results. Needs the following options set to work:
-i, --index - what you want to search against, can be either client, environment, node, role, or name of a data bag
-s, --search_query - what you're searching for, example: node name that includes the word "production" would be -s name:*production*
-a, --attribute - attribute you want results from, example: "ec2 public hostnames" would be a ec2.public_hostnames (can return results from any attributes that are set by ohai - check an ohai run on a node to see what attributes are available to you to return results for and the syntax needed to get them.)
EXAMPLE: ruby knife_search_csv.rb -i node -s name:*prod* -a ec2.public_hostname is equivalent to the knife search command of knife search node "name:*prod*" -a ec2.public_hostname
Results of script will generate a csv on your Desktop called "knife-search-node-ec2.public_hostname.csv".
Uses the knife ssh command to generate a csv file of the results. Needs the following options set to work:
-n, --name - name of the nodes that you want to run the knife ssh command against (can use wildcards like * )
-c, --command - command that you want run on the node names specified from --name option above
-a, --attribute - attribute you want returned along with the output of the knife ssh command that you ran
EXAMPLE: ruby knife_ssh_csv.rb -n "name:artifactory-*" -c "chef-client -v" -a fqdn is equivalent to knife ssh "name:artifactory-*" "chef-client -v" -a fqdn
Results of the script will generate a csv on your Desktop called "knife-ssh-artifactory-*-chef-client -v.csv"
