Using Chef Client with Cisco NX-OS
This chapter includes
the following sections:
Chef is an open-source
software package developed by Chef Software, Inc. It is a systems and cloud
infrastructure automation framework that deploys servers and applications to
any physical, virtual, or cloud location, no matter the size of the
infrastructure. Each organization is comprised of one or more workstations, a
single server, and every node that will be configured and maintained by the
chef-client. Cookbooks and recipes are used to tell the chef-client how each
node should be configured. The chef-client, which is installed on every node,
does the actual configuration.
A Chef cookbook is
the fundamental unit of configuration and policy distribution. A cookbook
defines a scenario and contains everything that is required to support that
scenario, including libraries, recipes, files, and more. A Chef recipe is a
collection of property definitions for setting state on the device. The details
for checking and setting these property states are abstracted away so that a
recipe may be used for more than one operating system or platform. While
recipes are commonly used for defining configuration settings, they can also be
used to install software packages, copy files, start services, and more.
