A chef is a configuration management tool which helps develop and operations teams manage applications and infrastructure in an efficient manner.
Many companies like Facebook use Chef software to control and manage their infrastructure
The cookbook is the fundamental unit of configuration and policy distribution. It contains all the details of a scenario. a scenario and contains everything that is required to support that scenario:
A chef is a powerful automation platform that transforms infrastructure into code. The Chef server is the main component which stores cookbooks, the policies that are applied to nodes, and metadata which has details of the registered nodes which are being managed by the chef-client.
Chef DK workstation is used for user interaction with Chef. In the Workstation users write and test cookbooks using tools and after testing upload to Chef Server using knife command line tools. Also, it provides the below
Chef-Client nodes are the machines managed by Chef. It is installed on each node which is required to configure the node to its desired state.
Chef workstation is a computer that has knife configured along with chef-client installed on it. Using knife we can author cookbooks, interact with Chef Server and with the nodes.
Workstation is used for the below purposes.
It describes the steps done by the chef-client when it is configuring a node . The below diagram shows the various stages which occur during a chef-client run.
Syntax : $ knife ssl check (options)
For example:
$ knife data bag create DATA_BAG_NAME (DATA_BAG_ITEM)
It is an agent which runs on every node that is managed by Chef. It is run to ensure the node into the desired state as given below
A chef_container resource is used to interact with container objects that exist on the Chef server.
Syntax:
chef_container 'name' do attribute 'value' # see properties section below ... action :action # see actions section below end
A data bag is a container of related data bag items, where each individual data bag item is a JSON file. The knife can load a data bag item by specifying the name of the data bag to which the item belongs and then the filename of the data bag item.
Syntax:
chef_data_bag 'name' do attribute 'value' # see properties section below ... action :action # see actions section below end
A Recipe is a collection of Resources which is used for configuring a piece of software. A Cookbook groups together Recipes and other information in a way that is more manageable than having just Recipes alone.
chef-apply is an executable program which runs a single recipe from the command line. It belongs to Chef Development Kit and very useful to work with resources.
The syntax for Chef-apply is:
chef-apply name_of_recipe.rb
chef-client is used with cookbooks. It is widely used in production purposes environments.
It is used to manage packages on ubuntu and debian platforms
It is used between chef-client and the Chef Server for secure communication and proper access to the data
1.Node's hostname / Public Ip Address
2.Node's userName and Password
3.Also, key details if it is used for authentication
Yes, both are the same. Resource attributes in any specific order as required. want.
A run-list must be in one of the below following formats:
'role[NAME]'
or
'recipe[COOKBOOK::RECIPE]'
Use a comma to separate roles and recipes when adding more than one item the run-list:
'recipe[COOKBOOK::RECIPE],COOKBOOK::RECIPE,role[NAME]'
Details of the bootstrap process are given below
1.Node downloads and installs chef-client.
2.chef-client registers with Chef Server and does the check-in.
One can validate if the node has successfully bootstrapped by checking the details in Chef Management Console and using commands knife node list and knife node show.
A knife is a command-line tool which provides an interface between a local chef-repo and the Chef server.
knife helps users to manage:
knife ec2, knife azure, knife blue box, knife eucalyptus, knife google, knife linode, knife OpenStack, and knife rackspace
It is a tool that comes along with chef-client installation, which can detect attributes on a node which is provided to the chef-client for use within cookbooks. It is run by the chef-client at the beginning of every Chef run to determine system state.
Set cookbook’s version number to 1.0.0 when it is ready to be used in production.
Starter Kit will create the necessary configuration files like chef directory, knife.rb, the ORGANIZATION-validator.pem, and USER.pem files etc. which is required to interact with the Chef server.
Diagnose subcommand is used to see details of computed diagnostic configuration for one or more instances. It has all the details updated in YAML format.
Syntax – $ kitchen diagnose PLATFORMS (options)
When a chef-client run is executed and if there any issues, Handlers are used to identify situations and remediate the issues. There are 3 types of handlers
Vagrant helps Test Kitchen communicate with VirtualBox and configures resources like memory and network settings.
