6.wordpress-k8s.yml 적용
kubectl apply -f wordpress-k8s.yml

7.배포상태 확인
kubectl get all

워드프레스 포드가 Rnning인지 확인, service/wordpress포트 확인(30496)

8.IP확인
minikube ip

9.접속
브라우저 하나 띄우고 "ip주소":"포트" 입력(이거 몰라서 기록하려고 작성함 + 도커 꺼놓고 하는게 좋음. 워드프레스 떳다가 안떠서 컴터 포멧까지 갔는데 도커 때문임ㅠ)

10.결과

11.워드프레스 리소스 제거
kubectl delete -f wordpress-k8s.yml
