드라이버는 hyper-v를 사용하고 있습니다.

안녕하세요! 인증서 이슈를 재현하기 어려워 답변이 늦었습니다 ㅠ
명령어를 변경하고 다시 테스트 부탁드립니다.
minikube start --insecure-registry=production.cloudflare.docker.com:443,docker.io:443
설정이 정상적으로 되었는지 확인하려면 minikube ssh 로 콘솔 접근 후 다음 명령어로 확인할 수 있습니다.
cat /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2376 -H unix:///var/run/docker.sock --default-ulimit=nofile=1048576:1048576 --tlsverify --tlscacert /etc/docker/ca.pem --tlscert /etc/docker/server.pem --tlskey /etc/docker/server-key.pem --label provider=hyperkit --insecure-registry 10.96.0.0/12 --insecure-registry production.cloudflare.docker.com:443 --insecure-registry docker.io:443
동일하게 오류가 발생한다면 기본 이미지 경로를 변경해보시겠어요?
mysql:5.6 -> docker.io/library/mysql:5.6
wordpress:5.5.3-apache -> docker.io/library/wordpress:5.5.3-apache
0
minikube delete 하시고 옵션을 추가하고 새로 만들어도 동일한 메시지가 나오시나요?
minikube start --insecure-registry="0.0.0.0/0"
minikube 실행시 driver가 무엇이였는지 알 수 있을까요? docker 드라이버를 사용하셨다면 현재 docker for desktop 설정을 변경해야 할 것 같습니다.
docker engine 설정에서 insecure-registry 설정을 추가해보시겠어요?
{
"insecure-registries": ["0.0.0.0/0"]
}

동일한 오류가 계속 발생하는데 다른 방법은 없을까요? 사무실 노트북에서 교육 수강 중이라 다른 네트워크 환경으로는 쉽지 않은 상황입니다.

안녕하세요! 상세한 로그 감사합니다. 로그 상으로 봤을때 도커 이미지를 다운받는데 실패하여 ImagePullBackOff 에러가 발생한 것으로 보입니다.
테스트하고 계신 환경의 네트워크가 사설인증서가 필요한 것으로 보입니다. 다른 네트워크 망에서 테스트하시거나 minikube를 생성할때 --insecure-registry 옵션을 이용해보시겠어요?
minikube start --insecure-registry="0.0.0.0/0"
