并且必须有某个东西负责**更新 HTTPS 证书**，它可以是相同的组件，也可以是不同的组件。


### HTTPS 示例工具

您可以用作 TLS 终止代理的一些工具包括：

* Traefik
     * 自动处理证书更新 ✨
* Caddy
     * 自动处理证书更新 ✨
* Nginx
     * 使用 Certbot 等外部组件进行证书更新
* HAProxy
     * 使用 Certbot 等外部组件进行证书更新
* 带有 Ingress Controller(如Nginx) 的 Kubernetes
     * 使用诸如 cert-manager 之类的外部组件来进行证书更新
* 由云服务商内部处理，作为其服务的一部分（请阅读下文👇）
