Greetings my fellow Technology Advocates and Specialists.
This is Chapter #2 of my Packer Series.
In this Session, I will demonstrate how to Automate image builds with Packer in Azure using Azure Devops.
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. CI/CD Platform is Microsoft Azure Devops .
3. For the purpose this blog post, we are building image for Windows using Packer and Azure Devops.
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. Azure DevOps Organisation and Project.
6. Azure Resource Manager Service Connection in Azure DevOps.
7. Key Vault with 4 Secrets stored - 1) Azure Subscription ID, 2) Azure Tenant ID, 3) Azure Service Principal Client ID, and 4) Azure Service Principal Secret.
PACKER TEMPLATE (am-packer-template-v2.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.
