kubernetes1.5版本deployment部署的apiVersion为extensions/v1beta1 ，yml脚本如下：
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: test-service-deploy
labels:

app: nginx

spec:
replicas: 2
selector:

matchLabels:
  app: nginx

template:

metadata:
  labels:
    app: nginx
spec:
  containers:
  - name: nginx
    image: nginx:latest
    ports:
    - containerPort: 80
    1.6.0版本中的apiVersion写法为apps/v1beta1

apiVersion: apps/v1beta1
kind: Deployment
metadata:
name: test-service-deploy
labels:

app: nginx

spec:
replicas: 2
selector:

matchLabels:
  app: nginx

template:

metadata:
  labels:
    app: nginx
spec:
  containers:
  - name: nginx
    image: nginx:latest
    ports:
    - containerPort: 80
  目前官网的apiVersion:为apps/v1，yml脚本如下：

apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
labels:

app: nginx

spec:
replicas: 3
selector:

matchLabels:
  app: nginx

template:

metadata:
  labels:
    app: nginx
spec:
  containers:
  - name: nginx
    image: nginx:1.14.2
    ports:
    - containerPort: 80

apiVersion内容不对会导致创建时报错，无法正常创建。
