Hi, what were the actual problems for you to deploy AWX on microk8s? If your storage provisioner, ingress controller, and load balancer are configured correctly, there are less differences between deploying on single node cluster and deploying on multi nodes cluster.
Sorry if this is a stupid recommendation but before deploying AWX Operator and AWX, I recommend you to test your cluster with minimal web app by some steps like this, to ensure your LB and ingress work as expected: Question about adding remote EE node to AWX k8s cluster - #9 by kurokobo
This should work, but if you are interested in more native way in K8s, you can create nfs based PV instead of hostPath based one: Persistent Volumes | Kubernetes. Also there are good CSI for NFS: https://microk8s.io/docs/how-to-nfs
