How to solve Minikube coreDNS i/o timeout on a Mac

Just a note about restarting a Minikube instance running with podman on a Mac.

You might have seem a problem in the coreDNS pods being unable to resolve naming.

Try using podman driver and the CRI-O container runtime instead of Docker runtime:

minikube start --container-runtime=cri-o

Steps to reproduce

1. Apply the resources.yaml file kubectl apply -f resources.yaml -n <namespace>
2. This will deploy a default InMemory Broker, a Trigger filtering by source: /from/ping and a custom event display, so we can see the content-type header.
3. Run the following command from your terminal to create a temporary container to run curl:

kubectl run curl --image=radial/busyboxplus:curl -i --tty --rm

4. In a new terminal window, run:
