如何在家庭网络中通过Traefik访问Docker容器

首先，确认在主机上已经安装了Docker和Traefik。

创建一个网络以在其中运行Docker容器：

docker network create my_network

运行Docker容器并将其添加到网络中：

docker run --name my_container --network my_network -d my_image

确认Traefik已经配置并正在运行。这里给出的是一个简单的Traefik Docker Compose文件：

version: '2'

services:
  reverse-proxy:
    image: traefik:v2.5
    ports:
      - '80:80'
      - '8080:8080'
    volumes:
      - '/var/run/docker.sock:/var/run/docker.sock:ro'
      - './traefik.toml:/traefik.toml:ro'
      - './acme.json:/acme.json'
    labels:
      - 'traefik.enable=true'
      - 'traefik.http.routers.dashboard.rule=Host(`traefik.mydomain.com`)'
      - 'traefik.http.routers.dashboard.entrypoints=websecure'
      - 'traefik.http.routers.dashboard.service=api@internal'
      - 'traefik.http.routers.dashboard.tls=true'
      - 'traefik.http.routers.dashboard.tls.certresolver=myresolver'
      - 'traefik.http.routers.dashboard.middlewares=dashboard-auth@file'
      - 'traefik.http.middlewares.dashboard-auth.basicauth.usersfile=/auth/dashboard'

networks:
  default:
    external:
      name: my_network

Traefik已经配置好后，我们需要在Docker容器中添加标签以告诉Traefik如何代理它。例如：

docker run --name my_container --network my_network -d my_image
  -l "traefik.enable=true"
  -l "traefik.http.routers.my_container.rule=Host(`my_container.mydomain.com`)"
  -l "traefik.http.routers.my_container.entrypoints=web"
  -l "traefik.http.routers.my_container.service=my_container"
  -l "traefik.http.services.my_container.loadbalancer.server.port=8080"

最后，我们需要将我们的主机名解析到我们的Traefik主机中。在你的本地/etc/hosts文件中添加一行：

192.168.1.100    traefik.my
