docker-compose安装adguard给局域网提供dns加速服务

启动配置

docker-compose.yaml配置文件

version: '3.3'
services:
  adguard:
    image: adguard/adguardhome:latest
    container_name: adguard
    restart: unless-stopped
    volumes:
      - ./workdir:/opt/adguardhome/work
      - ./confdir:/opt/adguardhome/conf
    ports:
      - 53:53/tcp
      - 53:53/udp
      - 81:80/tcp
      - 3000:3000/tcp
    networks:
      custom-bridge:
    logging:
      options:
        max-size: "10m"
networks:
  custom-bridge:
    external: true

docker-compose up -d启动服务，然后有一个引导页面，进行初始化配置，自定义配置admin/1到8

路由器上配置全局dns

处理容器的dns问题

连接到这个路由器的linux上的docker在解析dns时有问题，无法正确解析，因为docker配置的默认dns地址时127.0.0.11，很奇怪是这个地址，所以在容器运行时配置下默认的dns，在docker-compose.yaml中添加dns字段，这个ip地址是adguard所在的ip，用宿主机的ip就好：172.18.0.1，这样就比较固定，adguard以后可以随便改变docker网桥中的ip。
比如：

version: '3.3'

services:
  alist:
    image: xhofe/alist:v3.32.0
    container_name: alist
    restart: unless-stopped
    environment:
      - PUID=0
      - PGID=0
      - UMASK=022
    volumes:
      - ./etc:/opt/alist/data
    ports:
      - 5244:5244
    networks:
      custom-bridge:
    logging:
      options:
        max-size: "10m"
    dns: 172.18.0.1
networks:
  custom-bridge:
    external: true

或者修改docker daemon的东西，两种方式都可以生效，随便选一种就好。临时配置用上一种，永久配置用下一种
