1.解析报错现象
[root@lanxin01 log]# kubectl exec -it permission-service-768874bbf-6wfjr -- nslookup devau.cnooc.com.cn Server: 172.21.0.10 Address: 172.21.0.10#53 ** server can't find devau.cnooc.com.cn.openstacklocal: SERVFAIL
2.发现宿主机resolv.conf 有openstacklocal信息
cat resolv.conf ; generated by /usr/sbin/dhclient-script search openstacklocal nameserver 10.77.10.10 nameserver 10.77.10.11
3解决办法
把resolv.conf 的serarch openstacklocal注释或者删除， 重启所有pod， 问题解决
