Knife Block

Green and Secure IT Limited often have a need to work with multiple chef servers at the same time, be it due to testing/development/live scenarios or purely through working for a number of clients at once.

The knife block plugin has been created to enable the use of multiple knife.rb files against multiple chef servers.

The premise is that you have a "block" in which you store all your "knives" and you can choose the one best suited to the task.

Requirements

At present, knife-block requires ruby 1.9.2 or above. This is owing to the use of "Dir.home()" to find a user's home directory.

Installation

gem install knife-block

How does it work?

Knife looks for knife.rb in ~/.chef - all this script does is create a symlink from the required configuration to knife.rb so that knife can act on the appropriate server.

Create a knife-<service_name>.rb configuration file in your ~/.chef directory for each Chef server that you wish to connect to.

Please note - this script will check to see if knife.rb exists and whether it is a symlink or not.

If knife.rb is not a symlink, the program will exit immediately and tell you what to do.

List all available servers

(This command will also tell you which server is currently selected)

knife block list

The available chef servers are:
    * local-testing [ Currently Selected ]
    * opscode-hosted-chef

Change to a new server

knife block use <server_name>

You are asking to change from local-testing to opscode-hosted-chef. Are you sure? (Y/N) y
The knife configuration has been updated to use opscode-hosted-chef

Create a new server

(Launches "knife configure" and creates $HOME/.chef/knife-<friendlyname>.rb)

knife block new <friendlyname>

Berkshelf integration

Knife block supports Berkshelf, however, the berkshelf config files must be manually created and named "config-<block>.json" and put in the Berkshelf directory (typically ~/.berkshelf). In the future, these files could be automatically created by knife block.

These knife plugins are supplied without any warranty or guarantees regarding suitability for purpose.

The code requires far more tests than the simple one that currently exists.

Having said all of that, it works for us!
