title: 与 Traefik 配合使用
description: 使用 Traefik 管理 Halo 服务的反向代理
---
## Halo 部署
参见 [使用 Docker Compose 部署](../docker-compose.md)
:::info
`「反向代理」` 部分不进行操作,保证 Halo 服务运行无误即可。
:::
## 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
```yaml {4-5,16,20,25-31} showLineNumbers
version: "3.8"
networks:
traefik:
external: true
halo:
services:
halo:
image: halohub/halo:2.14
container_name: halo
restart: on-failure:3
volumes:
- ./halo2:/root/.halo2
networks:
- traefik
- halo
command:
# 外部访问地址,请根据实际需要修改
- --halo.external-url=https://yourdomain.com
labels:
traefik.enable: "true"
traefik.docker.network: traefik
traefik.http.routers.halo.rule: Host(`yourdomain.com`)
traefik.http.routers.halo.tls: "true"
traefik.http.routers.halo.tls.certresolver: myresolver
traefik.http.services.halo.loadbalancer.server.port: 8090
```
