Building Images for Azure

These images are designed for use with [Cluster API Provider Azure](Cluster API Provider Azure) (CAPZ). Learn more on using custom images with CAPZ.

Prerequisites for Azure

• An Azure account
• The Azure CLI installed and configured
• Set environment variables for AZURE_SUBSCRIPTION_ID, AZURE_CLIENT_ID, AZURE_CLIENT_SECRET

Building Images

The build prerequisites for using image-builder for building Azure images are managed by running:

make deps-azure

Building Managed Images in Shared Image Galleries

From the images/capi directory, run make build-azure-sig-ubuntu-1804

Building VHDs

From the images/capi directory, run make build-azure-vhd-ubuntu-1804

If building the windows images from a Mac there is a known issue with connectivity. Please see details on running MacOS with ansible.

Developer

If you are adding features to image builder than it is sometimes useful to work with the images directly. This section gives some tips.

Provision a VM directly from a VHD

After creating a VHD, create a managed image using the url output from make build-azure-vhd-<image> and use it to create the VM:

az image create -n testvmimage -g cluster-api-images --os-type <Windows/Linux> --source <storage url for vhd file>
az vm create -n testvm --image testvmimage -g cluster-api-images
