Azure Managed Image
Bake a Canonical Ubuntu 24.04 managed image with Packer azure-arm on Standard_D2s_v3 in eastus, prove it with az image show, then delete the image and resource group.
Lab Overview
This is the hands-on lab for Section 8 of Packer 101. You write an azure-arm template that selects Canonical Ubuntu 24.04 LTS (URN Canonical:ubuntu-24_04-lts:server:latest), launches a Standard_D2s_v3 builder in eastus, provisions a marker file, deprovisions with waagent, and captures a uniquely named managed image into a resource group that setup already created. You intentionally break the template, read the validate error, and fix it. After the bake you prove the image with the Azure CLI, then delete the managed image and the resource group so leftover images do not leak cost.
You will:
- Confirm Packer 1.16.0 and Azure service principal credentials on the lab host
- Confirm the unique packer-101 resource group in eastus
- Write azure-ubuntu.pkr.hcl with required_plugins azure ~> 2 and managed_image_*
- Run packer init, fmt, and validate, then recover from a deliberate SKU and
resource group mistake
- Build the managed image, prove it with az image show, and clean up image then RG
