dns 服务器使用

一. 配置文件

• docker-compose配置文件(docker-compose.yaml)

version: '2'

services:
  dns:
    container_name: dns 
    image: jpillora/dnsmasq 
    restart: always
    volumes:
      - ./dnsmasq.conf:/etc/dnsmasq.conf
    #command: mongod     
    environment:
      - HTTP_USER=admin
      - HTTP_PASS=admin
    ports:
      #- 27017:27017
      - 53:53/udp
      - 8080:8080 
    logging:
      driver: "json-file"
      options:
        max-size: "10m"
        max-file: "10"

• dns配置文件自定义域名解析(dnsmasq.conf)

#dnsmasq config, for a complete example, see:
#  http://oss.segetech.com/intra/srv/dnsmasq.conf
#log all dns queries
log-queries
#dont use hosts nameservers
no-resolv
#use cloudflare as default nameservers, prefer 1^4
server=1.0.0.1
server=1.1.1.1
strict-order
#serve all .company queries using a specific nameserver
server=/company/10.0.0.1
#explicitly define host-ip mappings
address=/myhost.company/10.0.0.2

二. 使用步骤

• 启动dns服务
  在机器a(ip=192.168.0.110)上执行

  docker-compose -f docker-compose.yaml up -d
  

• 修改 /etc/resolv.conf 文件
  在机器a和b上

  nameserver 127.0.0.1 # dns服务与其他容器在同一台机器上时必须添加(否则可以不加)
  nameserver 192.168.0.110 # 192.168.0.110 为dns服务的ip
  

• 在浏览器中打开192.168.0.110:8080可以在线,查看,修改,保存,重启

三. 接口

1. 保存接口

• 方法: POST
• url: /save
• header:

key	value	备注
Accept-Encoding	gzip, deflate, br
Content-Type	application/json
Authorization	Basic YWRtaW46YWRtaW4=	用户名,密码的base64编码

• body:
  特别注意每个配置项一定要用\n隔开

{
    "/etc/dnsmasq.conf": "#dns解析日志\nlog-queries\nserver=223.5.5.5\n#定义主机与IP映射\naddress=/h0/172.17.205.28 \naddress=/h1/192.168.0.15"
}

2. 重启接口

• 方法: PUT
• url: /restart
• header:
  | key | value | 备注 |
  | --------------- | ---------------------- | ----------------------- |
  | Accept-Encoding | gzip, deflate, br | |
  | Content-Type | application/json | |
  | Authorization | Basic YWRtaW46YWRtaW4= | 用户名,密码的base64编码 |

四. 注意事项

• dns服务与其他容器在同一台机器上时必须在 /etc/resolv.conf 在 nameserver 127.0.0.1 并放在第一行
