在任务中：等待auth-pdp启动auth-pdp pod不能到达mariadb-0。有人遇到过这个问题吗？

我检查了mariadb容器是否正在运行，然后意识到它没有IP地址。
kubectl -n kube-system get pods -o wide
...
mariadb-0 1/1 Running 0 7m <none> 34.65.234.2
...
然后我尝试了可以从本地终端到达的端口转发mariadb
kubectl -n kube-system port-forward mariadb-0 8080:3306 &

我退出了auth-pdp pod尝试卷曲其他服务
bash-4.4# env | grep -i mongo

It looks like you are trying to access MongoDB over HTTP on the native driver port.
我查看了mariadb pod的界面，发现了以下内容：

ens4 NIC具有与Pod运行所在的节点相同的IP地址。它没有唯一的地址。然后解决以下问题：
k exec -it auth-idp-bkqwf -c init-mariadb bash
bash-4.4# curl 10.240.0.11:3306 --output dummy.txt
