I would like to do two things with MicroK8s:

Answer 1

If you need expose a service publicly with HTTPS and authentication, that may become rather involved, as you need configure a) ingress, b) TLS certificate service - i.e. using Lets Encrypt, c) authentication proxy, d) implement user authorization in your app.

If your K8S cluster is running on a server with no public IP, that brings an additional complication, as you need penetrate NAT.

https://github.com/gwrun/tutorials/tree/main/k8s/pod demonstrates how to securely expose k8s service running on microk8s cluster with no public IP as publicly accessible HTTPS with OAuth authentication and authorization, using Kubernetes Dashboard as a sample service.
