Set kubectl context to "kind-wslkind"
You can now use your cluster with:
 
kubectl cluster-info --context kind-wslkind
 
Not sure what to do next?  Check out https://kind.sigs.k8s.io/docs/user/quick-start/
❯ kubectl cluster-info --context kind-wslkind
Kubernetes control plane is running at https://127.0.0.1:40805
CoreDNS is running at https://127.0.0.1:40805/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
 
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
