I am documenting this because it took a lot of effort to get to these steps and will be useful to someone else.
One cannot use WSL and Docker to run networking on Kubernetes. See this note

The solution was to
1) remove minikube from WSL
minikube delete --purge
2) Then installed VirtualBox on Windows
3) Install Ubuntu
4) Install docker then minikube on Ubuntu
5) Start minikube
minikube start --memory=6g --cpus=4 --driver=docker --cni=calico
If necessary, set the context:
kubectl config view
kubectl config use-context minikube
kubectl config set-context --current --namespace=default
Now
$ k get pods -A
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system coredns-787d4945fb-c5lf2 1/1 Running 0 76s
kube-system etcd-minikube 1/1 Running 0 90s
kube-system kube-apiserver-minikube 1/1 Running 0 88s
kube-system kube-controller-manager-minikube 1/1 Running 0 88s
kube-system kube-proxy-ctcsl 1/1 Running 0 76s
kube-system kube-scheduler-minikube 1/1 Running 0 90s
kube-system storage-provisioner 1/1 Running 1 (64s ago) 85s
Now all the networking that earlier failed, is now working!
TaDa! 😋
