如何使用外部服务

使用无头服务+endpoints

https://www.cnblogs.com/lvzhenjiang/p/14445315.html

apiVersion: v1
kind: Service
metadata:
  name: mysql
  namespace: default
spec:
  clusterIP: None # 无头service
  ports:
  - name: mysql
    port: 3306
    protocol: TCP
    targetPort: 3306
  type: ClusterIP
 
---
apiVersion: v1
kind: Endpoints
metadata:
  name: mysql
  namespace: default
subsets:
- addresses:
  - ip: 192.168.20.2
  ports:
  - name: mysql
    port: 3306
    protocol: TCP
 

使用service的ExternalName

apiVersion: v1
kind: Service
metadata:
  name: service-externalname
  namespace: dev
spec:
  type: ExternalName # service类型
  externalName: www.baidu.com  #改成ip地址也可以
