+
+### 操作步骤：
+
+登录腾讯云控制台，搜索进入 **SSL 证书**管理页面。

+
+选择 **自动 DNS 验证**并勾选 **自动删除旧验证记录**，提交后等待证书签发。
+
+证书签发后，在下载界面选择 **Nginx**格式，下载包含 `.crt`和 `.key`文件的证书包。

+
+## 二、证书部署
+
+### 部署流程：
+
+​	登录 Kubernetes 集群的 Master 节点，进入目标域名对应的证书目录。
+
+​	将下载的 `.crt`和 `.key`文件上传至服务器，覆盖原有证书文件。
+
+​	执行相应的脚本完成证书更新：**首次部署**：使用 `make-k8s-tls-secret.sh`**证书续期**：使用 `update-xxx-tls-secret.sh`
