kubernetes集群内通过endpoint访问外部服务

kubernetes内的服务访问集群外独立的服务最好通过endpoint方式,例如MySQL

1.创建mysql-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: mysql-production
  namespace: ms
spec:
  ports:
    - port: 3306
      targetPort: 3306
      protocol: TCP

2.创建mysql-endpoints.yaml

kind: Endpoints
apiVersion: v1
metadata:
  name: mysql-production
  namespace: ms
subsets:
  - addresses:
      - ip: 10.255.20.176
    ports:
      - port: 3306

3.查看 service

4.通过telnet测试
