Unable to generate a cloud image for Azure

There is no Azure image generated when trying to build using the below definition.

kind: OSArtifact
apiVersion: build.kairos.io/v1alpha2
metadata:
  name: azure-hello-kairos-cloud
spec:
  imageName: "quay.io/kairos/core-opensuse-leap:latest"
  azureImage: true
  bundles:
    # Bundles available at: https://packages.kairos.io/Kairos/
    - quay.io/kairos/packages:helm-utils-3.13.0
  cloudConfigRef:
    name: cloud-config
    key: userdata
  exporters:
    - template:
        spec:
          restartPolicy: Never
          containers:
            - name: upload
              image: quay.io/kairos/osbuilder-tools:latest
              command:
                - bash
              args:
                - -c
                - |
                  for f in $(ls /artifacts)
                  do
                    curl -T /artifacts/$f http://osartifactbuilder-operator-osbuilder-nginx/upload/$f
                  done
              volumeMounts:
                - name: artifacts
                  mountPath: /artifacts

Analysis and rootcause

The OSArtifact pod runs multiple containers to build the image but the container to build Azure image fails as it expects a raw image as an input argument which it fails to find as there is no container running to build a raw image.

build-azure-cloud-image container logs:

Containers in pod

  initContainers:
    - name: pull-image-baseimage
      image: quay.io/kairos/osbuilder-tools:v0.7.0
      ...
    - name: pull-image-0
      image: quay.io/kairos/osbuilder-tools:v0.7.0
    ...
  containers:
    - name: build-azure-cloud-image
      image: quay.io/kairos/osbuilder-tools:v0.7.0
      command:
        - /bin/bash
        - '-cxe'
      args:
        - >-
          /azure.sh /artifacts/azure-hello-kairos-cloud.raw
          /artifacts/azure-hello-kairos-cloud.vhd
    - name: create-image
      image: quay.io/kairos/osbuilder-tools:v0.7.0
      command:
        - /bin/bash
        - '-cxe'
      args:
        - >-
          tar -czvpf test.tar -C /rootfs . && luet util pack
          quay.io/kairos/core-opensuse-leap:latest test.tar
          azure-hello-kairos-cloud.tar && chmod +r azure-hello-kairos-cloud.tar
          && mv azure-hello-kairos-cloud.tar /artifacts

Possible solution

The build-azure-cloud-image container could include the script(raw-images.sh) to build the raw image and thus provide input for the azure.sh to create the vhd.

I expect the same issue to happen for gce image build process as well.
