Let’s get an overview of Microsoft Azure cloud and, how the popular configuration management tool Chef can be installed on Azure for making them work together.
Chef Introduction
Chef is a configuration management tool that turns infrastructure into code. You can easily configure your server with the help of Chef. Chef will help you automate, build, deploy, and manage the infrastructure process.
If you want to know more about Chef, please refer to https://docs.chef.io/index.html.
In order to know how you can create a user account on hosted Chef, please refer to:https://manage.chef.io/signup; alternatively, use open-source Chef by referring to:https://docs.chef.io/install_server.html.
Microsoft Azure
Microsoft Azure is a cloud computing platform and infrastructure created by Microsoft for building, deploying, and managing applications and services through a global network of Microsoft-managed datacenters.
It provides both PaaS and IaaS services and supports many different programming languages, tools, and frameworks, including both Microsoft-specific and third-party software and systems.
For more details refer to: http://azure.microsoft.com/en-in/ andhttp://msdn.microsoft.com/en-us/library/azure/dd163896.aspx.

We need your Chef’s account organization_validation key, rb and run_list.
Sample format for client.rb file:
log_location: STDOUT chef_server_url "https://api.opscode.com/organizations/" validation_client_name "-validator" +36+9
1. From Azure portal log into your azure account at https://portal.azure.com
1.1 List existing virtual machines:
1.2 Select existing VM:
1.3 Click the Extensions section:
1.4 Select Add Extension:
1.5 Select the Chef extension:
1.6 Click the Create button:
1.7 Upload Chef configuration files:
1.8 You can now see the Chef extension for VM:

2. Azure PowerShell CLI Tool
Azure PowerShell is a command line tool used to manage Azure cloud resources. You can use cmdlets to perform the same tasks that you can perform from the Azure portal.
Refer- http://msdn.microsoft.com/en-us/library/azure/jj156055.aspx
Prerequisites
Install Azure PowerShell Tool; refer to http://azure.microsoft.com/en-in/documentation/articles/install-configure-powershell/
Azure user accounts publish settings file.
We are going to use Azure PowerShell cmdlets to install the Chef extension on Azure VM.
2.1 Import your Azure user account into your PowerShell Session. Download subscription credentials for accessing Azure. This can be done by executing a cmdlet.

2.2 Create a new Azure VM and install the Chef extension
# Set VM and Cloud Service names
PS C:\> $vm1 = "azurechef"
PS C:\> $svc = "azurechef"
PS C:\> $username = 'azure'
PS C:\> $password = 'azure@123'
PS C:\> $img =
#Note- Try Get-AzureVMImage cmdlet to list images
PS C:\> $vmObj1 = New-AzureVMConfig -Name $vm1 -InstanceSize Small -ImageName $img
#Add-AzureProvisioningConfig for Windows OR Linux VM
# For Windows VM
PS C:\> $vmObj1 = Add-AzureProvisioningConfig -VM $vmObj1 -Password $password -AdminUsername
$username –Windows
or
# For Linux VM
PS C:\> $vmObj1 = Add-AzureProvisioningConfig -VM $vmObj1 -Password $password -LinuxUser
$username -Linux
# Set AzureVMChefExtension for Windows OR Linux VM
# For Windows VM
PS C:\> $vmObj1 = Set-AzureVMChefExtension -VM $vmObj1 -ValidationPem "C:\\users\\azure\
\msazurechef-validator.pem" -ClientRb "C:\\users\\azure\\client.rb" -RunList "getting-started"
-Windows
or
# For Linux VM
PS C:\> $vmObj1 = Set-AzureVMChefExtension -VM $vmObj1 -ValidationPem "C:\\users\\azure\
\msazurechef-validator.pem" -ClientRb "C:\\users\\azure\\client.rb" -RunList "getting-started" -Linux
# Create VM
PS C:\> New-AzureVM -Location 'West US' -ServiceName $svc -VM $vObj1
2.3 Install SetAzureVMChefExtension on existing azure VM:
# Get existing azure VM
PS C:\> $vmObj1 = Get-AzureVM -ServiceName -Name
# Set AzureVMChefExtension for Windows OR Linux VM
# For Windows VM
PS C:\> $vmObj1 = Set-AzureVMChefExtension -VM $vmObj1 -ValidationPem "C:\\users\\azure\
\msazurechef-validator.pem" -ClientRb "C:\\users\\azure\\client.rb" -RunList "getting-started" -Windows
or
# For Linux VM
PS C:\> $vmObj1 = Set-AzureVMChefExtension -VM $vmObj1 -ValidationPem "C:\\users\\azure\
\msazurechef-validator.pem" -ClientRb "C:\\users\\azure\\client.rb" -RunList "getting-started" -Linux
2.4 You can use following cmdlets to Remove Chef Extension from VM
# Get existing azure VM PS C:\> $vmObj1 = Get-AzureVM -ServiceName -Name # Remove Chef Extension from VM PS C:\> Remove-AzureVMChefExtension -VM $vmObj1 # Update VM PS C:\> Update-AzureVM -ServiceName $vmName -Name $vmName -VM $vmObj1
2.5 You can get current state of Chef Extension by using following cmdlet:
# Get existing azure VM PS C:\> $vmObj1 = Get-AzureVM -ServiceName -Name # Get Chef Extension details from VM PS C:\> Set-AzureVMChefExtension -VM $vmObj1
