test폴더 안에 yml파일과 sh파일을 작성해준다

 

kubectl create -f count.yml
kubectl get all -o wide

 

pod가 잘 실행 됐는지 확인해주고

curlt 10.0.2.126
kubectl exec -it count -c web-server -- ls -al /usr/local/apache2/htdocs
kubectl exec -it count -c web-server -- cat /usr/local/apache2/htdocs/index.html

 

mount된 폴더에 스크립트의 내용이 저장되는것을 확인 할 수 있다
