no kind "Deployment" is registered for version "apps/v1"

Deployment create or apply -f 파일이름 실행시 아래와 같이 에러 메세지 출력 (참고 apiVersion: apps/v1)

[root@hadoopm KUBE]# kubectl apply -f deployment-definition.yml

Error from server (BadRequest): error when creating "deployment-definition.yml": Deployment in version "v1" cannot be handled as a Deployment: no kind "Deployment" is registered for version "apps/v1"

이럴때 우선 k8s 버젼확인

root@hadoopm KUBE]# kubectl  version

Client Version: version.Info{Major:"1", Minor:"7", GitVersion:"v1.7.0", GitCommit:"d3ada0119e776222f11ec7945e6d

뭐 이렇게 하는게 맞는진 모르지만

암튼..

K8S가 1.9 밑에 버젼 1.8 이나 1.7 버젼이면 apiVersion: apps/v1beta1   <=요렇게 변경해준다 1.9이상이면 에러가 안나겠죵(apps/v1)

그럼 된다..
