我知道这个错误是因为新版本的kubernetes，但我无法解决这个问题，当我将扩展/v1beta1更改为apps/v1时，我开始在运行kubectl apply -f kubernets.yml时发现错误servicetwo。由于kuberentes 1.10运行得很完美，任何帮助都将不胜感激，感谢

除了更改为apps/v1，您还需要在spec:中添加新的必填字段selector:

像这样的东西应该对你有用：

apiVersion: apps/v1
kind: Deployment
metadata:
name: servicetwo
labels:
name: servicetwo
namespace: sock-shop
spec:
replicas: 1
selector:               // new required field
matchLabels:
name: servicetwo     // must match your labels
template:
metadata:
labels:
name: servicetwo
spec:
containers:
- name: servicetwo
image: nik/pythonserviceone
ports:
- containerPort: 5000
