# jenkins-manual pod 를 yaml 파일로 출력하기

kubectl get pod jenkins-manual -o yaml kubectl describe pod jenkins-manual

* 간혹가다 쿠버네티스 서비스를 실행시켰는데 상태가 pending인 경우가 있다.

이때는 worker들이 정상적으로 살아 있는지 확인 해야한다.

쿠버네티스의 마스터 노드는 단지 서비스를 관리하고 실행하는 역할이므로 실제 서비스는 worker노드에서 실행된다.

그래서 항상 worker노드가 정상적으로 실행이 되어 있어야만 서비스가 정상적으로 동작한다.
