VM Extensions : Building block for Devops
 Software provided both Microsoft or by trusted third-party
providers for Azure VMs to extend the functionality of the
VM.
 Windows and Linux support.
 Deploy to a running or a new VM.
 Programmability support.
 Update life cycle that’s independent of the VM.
 Enables dynamic composition on a VM.

Chef

Why Chef?

Solution with Chef

Chef on Azure
What is Chef? Chef is a configuration management tools for deploying &
managing infrastructure and applications.
- Infrastructure is code
- Declarative interface to resource
- Policy based configuration management.

Chef Helps Optimize Your Use of Azure
 High scalability. Manage 10,000+ VMs with a single Chef server, or use Chef’s
SaaS option.
 Advanced workflow. Use Chef to implement best practices such as A/B
testing and test-driven infrastructure.
 Flexible, policy-based configuration. Easily define recipes for complex cloud
use cases and for enterprise application delivery. The Chef server stores and
indexes the attributes of each node in your network for dynamic configuration.
 Reusable recipes. Reuse recipes with custom data for specific situations. Chef
lets you separate configuration policy from configuration state.
 Service-oriented interface for customization. All of Chef’s functionality is
exposed through consistent REST APIs. This gives you tremendous flexibility
when designing custom workflows.

Simplify and Speed Up Configuration Tasks
 You can use Chef to manage every aspect of your Microsoft Azure cloud
environment.
 For example, how often do you need to create storage containers whenever
you configure a new VM? With Chef, you can write code that makes this
common task a versionable, repeatable process.
 azure_storage_container container_name do storage_account stg_account
access_key stg_key action :create end
 This code creates a storage container named container_name, if it doesn't
already exist. It's a part of the Azure cookbook,
 There's also a Chef plug-in, made specifically for Microsoft Azure, called knife-
azure. With this plug-in you can, for example, set affinity groups, set the name
of a storage account, and set the host name of the VM. Download the plug–in,
add your security credentials, and you"re ready to go.

Chef Concepts:
Knife : Cmdline tool to manage
infrastructure and bootstrap chef.
Resource : Fundamental building block,
piece of a system.
Recipe : ‘code’ for managing the resource.
Cookbook : Collection of recipes.
Runlist : A policy which needs to be
applied on the node.

Managing Infrastructure in Azure using Knife
Chef Server Account:
 Sign up for Hosted Chef account :
https://manage.opscode.com/signup
Setting up Chef Workstation:
 Download the starter kit from Chef server.
 Setup the workstation by downloading the chef-client :
https://www.getchef.com/download-chef-client/
 Install knife azure : gem install knife-azure
The workstation is now ready to manage VMs in Azure!

Managing Infrastructure in Azure using Knife
 Create a VM :
Download publish settings file from here :
https://manage.windowsazure.com/publishsettings/index?client=powershell
Knife azure image list --azure-publish-settings-file '/path/to/your/cert.publishsettingsfile'
knife azure server create
--azure-publish-settings-file '/path/to/your/cert.publishsettingsfile'
--azure-dns-name 'myservice'
--azure-source-image 'windows-image-name'
--ssh-user ‘testuser'
--ssh-password ‘azuredemo'
--azure-service-location "West US"

Azure Powershell :
Set-AzureVMChefExtension-VM <IPersistentVM> -ValidationPem <Validator.pem> -ClientRb
<Client.rb> -RunList <RunList>
Knife Command:
knife azure server create --azure-dns-name 'knifetest2' --bootstrap-protocol 'cloud-api‘ --
azure-source-image '3422a428aaf14529884165693cbb90d3__DreamFactory_1.7.8-0_-
_Ubuntu_14.04' --azure-service-location 'West US' --ssh-user 'kundanap' --ssh-password

Puppet

Puppet on Azure
What is Puppet? : Puppet is a configuration management system that
allows you to define the state of your IT infrastructure, then
automatically enforces the correct state.
Key Concepts:
- Supports easy to read declarative language.
- Enforces desired state on the system.
- Puppet Forge supports many ready to use modules.
- .

Automate your Microsoft Azure & Windows environments
 Deliver value to customers faster while keeping up with a relentless rate of
change, you need to automate your infrastructure all the way through — from
initial provisioning through application deployment, both on prem and in the
cloud.
 Puppet Enterprise lets you manage your infrastructure as code so you can
adopt DevOps practices, improving the speed, scale and reliability of your
systems.

Provision, configure & manage your Azure infrastructure
 Provision, configure & manage your Azure infrastructure
 Puppet Enterprise lets you automate the entire lifecycle of your Azure
infrastructure, from initial provisioning through application deployment.
 Our Azure module allows you to provision and manage Azure VMs, plus give
you consistency and visibility into your infrastructure.
 It's included in your Puppet Enterprise support package.

Enterprise-level support for Windows environments
 With thousands of modules available for free download from the Puppet Forge,
you don’t have to reinvent the wheel to automate critical tasks and services.
 For Puppet Enterprise customers who want extra assurance, we also
offer supported modules.
 Supported modules are rigorously tested, maintained for long term use, and
fully supported by Puppet.
 The Forge also offers approved modules for Windows that are fully tested and
meet our rigorous quality and usability requirements.

Puppet supported modules
 ACLs
 Azure
 PowerShell DSC
 PowerShell
 Registry
 Reboot

Puppet Terminology
What is Chef? Chef is a configuration management Manifest : A file containing code written in the
Puppet language,& managing infrastructure and applications. Manifest contains resources and
classes.
Resources : A unit of configuration, whose state can be managed by Puppet.
Module : A collection of classes, resource types, files, and templates, organized around a particular
purpose.
Catalog : A catalog is a document that describes the desired system state for one specific computer.
Catalogs are compiled from manifests by a puppet master server and served to agent nodes.
- Infrastructure is code
- Declarative interface to resource
- Policy based configuration management.
