# Azure Image Builder
Build Azure managed images and Azure Compute Gallery images using Packer's `azure-arm` builder.
**Reference:** [Azure ARM Builder](https://developer.hashicorp.com/packer/integrations/hashicorp/azure/latest/components/builder/arm)
> **Note:** Building Azure images incurs costs (compute, storage, data transfer). Builds typically take 15-45 minutes depending on provisioning and OS.
## Basic Managed Image
```hcl
packer {
required_plugins {
azure = {
source = "github.com/hashicorp/azure"
version = "~> 2.0"
}
}
}
variable "client_id" {
type = string
sensitive = true
}
variable "client_secret" {
type = string
sensitive = true
}
variable "subscription_id" {
type = string
}
variable "tenant_id" {
type = string
}
variable "resource_group" {
type = string
default = "packer-images-rg"
}
locals {
timestamp = regex_replace(timestamp(), "[- TZ:]", "")
}
source "azure-arm" "ubuntu" {
client_id = var.client_id
client_secret = var.client_secret
subscription_id = var.subscription_id
tenant_id = var.tenant_id
managed_image_resource_group_name = var.resource_group
managed_image_name = "my-app-${local.timestamp}"
os_type = "Linux"
image_publisher = "Canonical"
image_offer = "0001-com-ubuntu-server-jammy"
image_sku = "22_04-lts-gen2"
location = "East US"
vm_size = "Standard_B2s"
azure_tags = {
Name = "my-app"
BuildDate = local.timestamp
}
}
build {
sources = ["source.azure-arm.ubuntu"]
provisioner "shell" {
inline = [
"sudo apt-get update",
"sudo apt-get upgrade -y",
]
}
}
```
## Azure Compute Gallery
```hcl
source "azure-arm" "ubuntu" {
client_id = var.client_id
client_secret = var.client_secret
subscription_id = var.subscription_id
tenant_id = var.tenant_id
os_type = "Linux"
image_publisher = "Canonical"
image_offer = "0001-com-ubuntu-server-jammy"
image_sku = "22_04-lts-gen2"
location = "East US"
vm_size = "Standard_B2s"
shared_image_gallery_destination {
resource_group = "gallery-rg"
gallery_name = "myImageGallery"
image_name = "ubuntu-webapp"
image_version = "1.0.${formatdate("YYYYMMDD", timestamp())}"
replication_regions = ["East US", "West US 2"]
storage_account_type = "Standard_LRS"
}
}
```
## Authentication
### Service Principal
```bash
# Create service principal
az ad sp create-for-rbac \
--name "packer-sp" \
--role Contributor \
--scopes /subscriptions/<subscription-id>
# Set environment variables
export ARM_CLIENT_ID="<client-id>"
export ARM_CLIENT_SECRET="<client-secret>"
export ARM_SUBSCRIPTION_ID="<subscription-id>"
export ARM_TENANT_ID="<tenant-id>"
```
### Managed Identity
```hcl
source "azure-arm" "ubuntu" {
use_azure_cli_auth = true
subscription_id = var.subscription_id
# ... rest of configuration
}
```
## Build Commands
```bash
# Set authentication
export ARM_CLIENT_ID="your-client-id"
export ARM_CLIENT_SECRET="your-client-secret"
export ARM_SUBSCRIPTION_ID="your-subscription-id"
export ARM_TENANT_ID="your-tenant-id"
# Initialize plugins
packer init .
# Validate template
packer validate .
# Build image
packer build .
```
## 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

Install targets
Codex install prompt
Install the "azure-image-builder" agent skill from https://github.com/hashicorp/agent-skills/tree/main/plugins/packer/skills/azure-image-builder. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Build Azure managed images and Azure Compute Gallery images with Packer. Use when creating custom images for Azure VMs. After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"hashicorp-azure-image-builder","task":"Install azure-image-builder","agent":"codex","outcome":"success","install_used":true}. Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes. Recorded instruction path: plugins/packer/skills/azure-image-builder/SKILL.md. Recorded revision: c2d65dfe492f74d360d35b859b88932222470bd8. Confirm the source matches these instructions.
