1. 修改配置文件
/etc/kubernetes/plugins/dns-cache/nodelocaldns.yaml
sed 's/k8s.gcr.io/gcr.azk8s.cn\/google_containers/g
s/__PILLAR__DNS__SERVER__/192.168.0.10/g
s/__PILLAR__UPSTREAM__SERVERS__/192.168.120.52/g
s/__PILLAR__DNS__DOMAIN__/cluster.local/g' nodelocaldns.yaml |
kubectl apply -n kube-system -f -
2. 查看 DNSUPstream
[root@m1 ~]# kubectl get svc -n kube-system | grep dns
kube-dns ClusterIP 192.168.0.10 <none> 53/UDP,53/TCP,9153/TCP 6d20h
kube-dns-upstream ClusterIP 192.168.120.52 <none> 53/UDP,53/TCP 6d20h
node-local-dns ClusterIP None <none> 9253/TCP 6d20h
