Post troubleshooting, it looks like openstack-helm-infra/roles/build-images/tasks/kubeadm-aio.yaml "Kubeadm-AIO image build path with proxy" task is building a docker image. This docker image need not to be build by every host in the inventory file.

So to fix this we need need to update inventory file with k8s master (primary) hostgroup instead of all (hostgroup)
