Documentation

Azure Image Builder

Build Azure managed images and Azure Compute Gallery images using Packer's azure-arm builder.

Reference: Azure ARM Builder

Note: Building Azure images incurs costs (compute, storage, data transfer). Builds typically take 15-45 minutes depending on provisioning and OS.

Basic Managed Image

packer {
  required_plugins {
    azure = {
      source  = "github.com/hashicorp/azure"
      version = "~> 2.0"

Azure Compute Gallery

Authentication

Service Principal

Managed Identity

Build Commands

Common Issues

Authentication Failed

Verify service principal credentials
Ensure Contributor role on resource group
Check subscription and tenant IDs

Compute Gallery Version Exists

Image versions are immutable
Use unique version numbers with date/build number
Cannot overwrite existing versions

Timeout During Provisioning

Check network connectivity from build VM
Verify NSG rules allow required traffic
Increase timeout if needed
