## 简介
|
|
|
|
|
|
|
|
|
|
[Traefik](https://traefik.io/traefik/) 是一款开源的反向代理与负载均衡工具,它监听后端的变化并自动更新服务配置。
|
|
|
|
|
|
|
|
|
|
它与传统反向代理最大的区别,是支持声明式的动态路由规则,大大简化网关规则的配置。而且还有诸多实用特性,例如:健康检查、多实例负载均衡、能够实现 Let's Encrypt 证书的自动签发、验证与续期等等。

## 创建 Traefik
|
|
|
|
|
|
|
|
|
|
下面的配置中,创建了 Traefik 实例。并且做了基础的几项配置:
|
|
|
|
|
|
|
|
|
|
1. 监听了宿主机的 80、443 端口,并自动将 80 端口的请求重定向到 443 端口。[文档](https://doc.traefik.io/traefik/routing/entrypoints/)
|
|
|
|
|
2. 开启 Docker 服务发现,监听检测 Docker 容器声明的服务关系。[文档](https://doc.traefik.io/traefik/providers/docker/#provider-configuration)
|
|
|
|
|
3. 开启 Traefik Dashboard,建议使用二级域名的形式(示例:`traefik.yourdomain.com`)。[文档](https://doc.traefik.io/traefik/operations/dashboard/#dashboard-router-rule)
|
|
|
|
|
4. 开启证书自动生成,通过 ACME 自动管理 TLS 证书的申请、校验与续期。[文档](https://doc.traefik.io/traefik/https/acme/)
|
|
|
|
|
|
|
|
|
|
:::caution
|
|
|
|
|
ACME 证书 (`/acme.json`) 一定要 [持久化](https://doc.traefik.io/traefik/https/acme/#storage),否则每次重启 Traefik 服务,都会去申请签发证书。可能会触发 Let's
|
|
|
|
|
Encrypt 的 [速率限制](https://letsencrypt.org/zh-cn/docs/rate-limits/),导致签名的域名一段时间内无法签发新的证书。

## 配置 Halo 的反向代理
|
|
|
|
|
|
|
|
|
|
这里以最简配置(h2 数据库)Halo 服务的 Docker 配置举例。只需做以下调整:
|
|
|
|
|
|
|
|
|
|
1. 顶层 `networks` 中添加了外部网络 `traefik`
|
|
|
|
|
2. `services.halo.networks` 中添加了 `traefik` 网络
|
|
|
|
|
3. `services.halo.labels` 中声明了 Traefik 配置
|
|
|
|
|
1. 路由规则为 `yourdomain.com`
|
|
|
|
|
2. 开启 TLS
|
|
|
|
|
3. 指定了服务端口为 8090
|
|
