k8s 创建service

nginx-service.yaml

apiVersion: v1
kind: Service

spec:
  selector:
    app: nginx
  ports:
  - protocol: TCP
    port: 80
    targetPort: 80

创建service

kubectl create -f nginx-service.yaml

kubectl get svc nginx-service -o wide 

[root@centos-7 k8s-yaml]# kubectl get svc nginx-service -o wide
