+# dns 错误
+
+当你在 Kubernetes 集群中遇到 DNS 解析错误时，可以尝试以下步骤来解决问题：
+1. **检查 CoreDNS 状态**：
+   确保 CoreDNS Pod 正在运行且没有错误。使用以下命令检查 CoreDNS Pod 的状态：
+   ```bash
+   kubectl get pods -n kube-system -l k8s-app=kube-dns
+   ```
+   如果 Pod 处于 CrashLoopBackOff 或其他错误状态，查看日志以获取更多信息：
+   ```bash
+   kubectl logs -n kube-system -l k8s-app=kube-dns
+   ```
+
+2. 修改 /etc/resolv.conf 文件
+
+```bash
+sudo vim /etc/systemd/resolved.conf
+
+# 修改 DNS 服务器地址
+DNS=223.5.5.5 223.6.6.6
+# 重启 systemd-resolved 服务
+
+sudo systemctl restart systemd-resolved
+```
