Mongo部署和服务在集群中运行良好,但当我创建新的Mongo服务时,需要外部IP,然后删除所有应用程序 kubectl delete 蒙哥,再创造一次 kubectl apply

但DNS kubernetes不更新:

kubectl exec -it python-guestbook-backend-8544c67965-pxlj5 ping python-guestbook-mongodb
PING python-guestbook-mongodb.default.svc.cluster.local (172.20.74.79) 56(84) bytes of data.

仍然有旧的IP地址。

实际上,我错过了 endpoint

apiVersion: v1
metadata:
 name: python-guestbook-mongodb
spec:
 ports:
 - port: 27017
   targetPort: 27017
---
kind: Endpoints
apiVersion: v1
metadata:
 name: python-guestbook-mongodb
subsets:
 - addresses:
     - ip: x.x.x.x
