Greetings my fellow Technology Advocates and Specialists.
This is Chapter #1 of my Packer Series.
In this Session, I will demonstrate how to Automate image builds with Packer in Azure.
I had the Privilege to talk on this topic in ONE Azure Communities:-
NAME OF THE AZURE COMMUNITY TYPE OF SPEAKER SESSION
Cloud Lunch and Learn - 2024 Virtual
EVENT ANNOUNCEMENTS:-
Hashi Packer Series With Azure and Devops:-
Greetings to my fellow Technology Advocates and Specialists.
In this Session, I talk and run Demo on PACKER SERIES in below TECH COMMUNITIES :-
NAME OF THE TECH COMMUNITIES:-
Cloud Lunch and Learn - 2024
POINTS TO NOTE:-
1. Cloud Provider is Microsoft Azure .
2. For the purpose this blog post, we are building image for Windows using Packer.
PRE-REQUISITES:-
1. Azure Subscription.
2. Azure Resource Group.
3. Azure Service Principal - This will be used by Packer to Authenticate.
4. Azure Service Principal having "Contributor" RBAC on Subscription or on the specific Resource Group where Packer will create Image.
5. Download and Install Packer.
PACKER TEMPLATE (am-packer-template-v1.pkr.hcl):-
This template builds a Windows Server 2019 VM, installs IIS, then generalizes the VM with Sysprep.
The IIS install shows how you can use the PowerShell provisioner to run additional commands.
The final Packer image then includes the required software install and configuration.
source "azure-arm" "am-image" {
subscription_id = "210e66cb-55cf-424e-8daa-6cad804ab604"
tenant_id = "20516b3d-42af-4bd4-b2e6-e6b4051af72a"
client_id = "54b7f78d-6b11-466c-8172-5934f104e779"
client_secret = "xxxxxxxxxxxxxxxxxxxxxxx"
managed_image_name = "am-image-v1"
managed_image_resource_group_name = "am-packer-rg"
communicator = "winrm"
image_offer = "WindowsServer"
image_publisher = "MicrosoftWindowsServer"
image_sku = "2019-Datacenter"
location = "westeurope"
os_type = "Windows"
vm_size = "Standard_B4ms"
winrm_insecure = "true"
winrm_timeout = "5m"
winrm_use_ssl = "true"
winrm_username = "packeradmin"
}
build {
sources = ["source.azure-arm.am-image"]
provisioner "powershell" {
inline = ["Add-WindowsFeature Web-Server", "while ((Get-Service RdAgent).Status -ne 'Running') { Start-Sleep -s 5 }", "while ((Get-Service WindowsAzureGuestAgent).Status -ne 'Running') { Start-Sleep -s 5 }", "& $env:SystemRoot\\System32\\Sysprep\\Sysprep.exe /oobe /generalize /quiet /quit", "while($true) { $imageState = Get-ItemProperty HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Setup\\State | Select ImageState; if($imageState.ImageState -ne 'IMAGE_STATE_GENERALIZE_RESEAL_TO_OOBE') { Write-Output $imageState.ImageState; Start-Sleep -s 10 } else { break } }"]
}
}

Exit fullscreen mode
PACKER COMMANDS:-
Below follows the list of Packer commands.
Note:- "C:\Packer" Contains the Packer executable and Packer HCL Template.
.\packer.exe init C:\Packer\.
2. Format Packer Template:-
.\packer.exe fmt C:\Packer\.
.\packer.exe validate C:\Packer\.
.\packer.exe build C:\Packer\am-packer-template-v1.pkr.hcl
BELOW FOLLOWS ALL THE TROUBLESHOOTING STEPS:-
ERROR #1:-
Unknown source type "azure-rm". The source "azure-rm" is unknown by Packer, and is most likely part of a plugin that is not installed.
RESOLUTION:-
The Plugin was installed.
.\packer.exe plugins install github.com/hashicorp/azure
PACKER IMAGE BUILD SUCCESFULLY COMPLETED:-
1. Windows Image build execution with Packer completed successfully.
2. During the time, Packer build runs, an actual Virtual machine with all required resources gets created in a temporary resource group. The Windows VM Image gets created from that Virtual machine and its related resources. Once the Image is created successfully, the virtual machine and all its related resources gets deleted.
3. Finally, the Windows Image created using Packer.
Hope You Enjoyed the Session!!!
