Infrastructure As Code

Infrastructure deployments with IaC are repeatable and prevent runtime issues caused by configuration drift or missing dependencies. DevOps teams can work together with a unified set of practices and tools to deliver applications and their supporting infrastructure rapidly, reliably, and at scale. In this session we will look into topics like Azure Automation, Desired State Configuration, ARM Templates.

19. What is PowerShell DSC
    • Is a new configuration management platform. It does not go against
    Chef or puppet. It works with them.
    • Enables deployment of configuration data.
    • Fixes a configuration that has drifted away from the desired state.

20. VM Agents and Extensions
    • Azure VM Agent is a secured, light-weight process that runs
    extensions.
    • VMAccessAgent, DSC, ChefClient, DockerExtension
    • Azure Powershell DSC Extension does the job for DSC.

28. How to write configurations?
    • The Configuration block. This is the
    outermost script block. You define it by using
    the Configuration keyword and providing a
    name.
    • One or more Node blocks. These define the
    nodes (computers or VMs) that you are
    configuring. In the above configuration, there
    is one Node block that targets a computer
    named "TEST-PC1".
    • One or more resource blocks. This is where
    the configuration sets the properties for the
    resources that it is configuring. In this case,
    there are two resource blocks, each of which
    call the "WindowsFeature" resource.

30. How to do it with Powershell.
    $params = @{
    AutomationAccountName = 'daronautomation'
    ResourceGroupName = 'Group'
    SourcePath = 'C:\NewTestEnvironment.ps1'
    Published = $true
    Force = $true
    }
    $null = Import-AzureRmAutomationDscConfiguration $params

31. DSC Compilation
    $compParams = @{
    AutomationAccountName = 'daronautomation'
    ResourceGroupName = 'Group'
    ConfigurationName = 'NewTestEnvironment'
    }
    $CompilationJob = Start-AzureRmAutomationDscCompilationJob @compParams
    ## Wait for the DSC compile
    while($CompilationJob.EndTime -eq $null -and $CompilationJob.Exception -eq $null)
    {
    $CompilationJob = $CompilationJob | Get-AzureRmAutomationDscCompilationJob
    Start-Sleep -Seconds 3
    }

32. Attach it to the VM
    $nodeId = (Get-AzureRmAutomationDscNode -AutomationAccountName 'daronautomation' -
    ResourceGroupName 'Group' -Name 'YourVMName').Id
    $nodeParams = @{
    NodeConfigurationName = "NewTestEnvironment.TEST"
    ResourceGroupName = 'Group'
    Id = $nodeId
    AutomationAccountName = 'daronautomation'
    Force = $true
    }
    $node = Set-AzureRmAutomationDscNode @nodeParams
