Introducing Knife

Knife is a command-line tool that comes bundled with the Chef installation. Depending upon how Chef was installed, you may find the binary at any particular location on your workstation. Since I have installed Chef using rvm and gem packaging, it is found at ~/.rvm/gems/ruby-2.1.0/gems/chef-11.8.2/bin/knife.

Depending upon your setup, you may find it at some other location. Whatever the location, ensure that it is in your PATH variable.

Knife is used for almost every aspect of managing your interactions with chef-server. It helps us manage:

  • Cookbooks
  • Environments
  • Roles
  • Data bags
  • Nodes
  • API clients
  • Bootstrapping of instances
  • Searching for nodes
