I also ran into the issue above. I'm using rootless docker fwiw. As a workaround, I added the result of minikube ip as an insecure registry in my docker daemon and restarted it. I was able to docker push $(minikube ip):5000/<image>:<tag> and pulling on cluster side worked fine as localhost:5000/<image>:<tag>.
