What azure-image-builder does

The skill covers Packer’s azure-arm builder for producing a managed image or publishing one to Azure Compute Gallery. Its HCL examples configure an Ubuntu Linux image, a region and a VM size, with shell provisioning shown for package updates.

Authentication examples use either a Service Principal with environment variables or Azure CLI authentication through Managed Identity. The build workflow runs packer init ., packer validate . and packer build .. Gallery image versions cannot be overwritten, so each build needs a version that does not already exist.

What it helps with

build a managed Azure image from a Packer template
publish an Ubuntu image to Azure Compute Gallery
configure Packer credentials with a Service Principal
validate a template before building an image

Example prompts for the agent

Create a Packer template for an Ubuntu managed image in Azure.
Set up a Packer source that publishes to Azure Compute Gallery.
Check my Packer template and give me the commands to build the Azure image.
