•  Overview •  Chef Software Platform •  Building Blocks •  Automation Patterns

Overview

•  Chef is an automation framework that enables Infrastructure as Code

•  Chef leverages reusable definitions to automate desired state

•  Chef is API driven

•  Chef supports Linux variants, Unix variants, AIX and Windows, all as first class citizens.

Building Blocks: What is a Resource?

•  A Resource is a system state you define •  Example: Package installed, state of a service, configuration file existing

•  You declare what state you want the resource in. •  Chef automatically determines HOW that state is achieved

On Linux based OSes: On Windows based OSes:

Building Blocks: What is a Recipe?

•  A recipe is a collection of Resources •  Resources are executed in the order they are listed.

On Linux based OSes: On Windows based OSes:

Building Blocks: What is a Cookbook?

•  A cookbook is a set of recipes •  A cookbook is a defined set of items

and different outcomes that you expect to address •  A cookbook could have a recipe to install

apache2/httpd but also another set of recipes to activate modules required.

Building Blocks: What is a role?

•  Define reusable roles for Infrastructure Code

chef_type:                      role  default_attributes:      my-­‐app:          application:              package:          mysite-­‐A.tar.gz              package_sum:  73e5cf3287e4d903d3828da5be1ab228ea33152447551b4e489e659268f643b2              package_url:  http://demo-­‐framework.s3.amazonaws.com/mysite-­‐A.tar.gz  description:                  Role  for  a  myapp  webserver  env_run_lists:  json_class:                    Chef::Role  name:                                myapp_A_webserver  override_attributes:  run_list:      recipe[my-­‐app::application]      recipe[my-­‐app::webserver]  

Building Blocks: What is an Environment?

•  Define a reusable environments for Infrastructure Code

chef_type:                      environment  cookbook_versions:      database:  2.2.0    default_attributes:      myapp:          version:  1.2.3  description:                  for  development  nodes  json_class:                    Chef::Environment  name:                                development  override_attributes:

Building Blocks: What is a Data_Bag?

•  Define global variables accessible to all the things
