1、Docker-Compose的配置文件
用vi编辑器，创建文件：
vi docker-compose.yml
内容如下：
version: '3.6'
networks:
main:
ipam:
config:
- subnet: 10.10.1.0/24
services:
web:
image: 'sameersbn/bind:9.16.1-20200524'
container_name: dns
restart: always
networks:
main:
ipv4_address: 10.10.1.2
ports:
- '53:53/udp'
- '10000:10000/tcp'
volumes:
- '/mnt/data/dns-server:/data'
shm_size: '256m'保存后退出2、用docker-compose启动容器
- 可能提示没有安装docker-compose

- 再次用docker-compose启动容器
会发现linux系统已经能执行docker-compose命令，但是最终是报错。

上边提示的很清楚，因为DNS需要的UDP53端口，被Ubuntu占用了，
3、修改物理服务器
修改/etc/systemd/resolved.conf文件
root@amicore:~# cd /etc/systemd/ root@amicore:/etc/systemd# ls journald.conf logind.conf network networkd.conf pstore.conf resolved.conf sleep.conf system system.conf timesyncd.conf user user.conf root@amicore:/etc/systemd# vi resolved.conf
文件修改两个地方

确认一下是否生效了？
重新启动服务器后：
root@amicore:/etc/systemd# cd /etc root@amicore:/etc# vi resolv.conf
### 文件内容如下
# This is /run/systemd/resolve/resolv.conf managed by man:systemd-resolved(8). # Do not edit. # # This file might be symlinked as /etc/resolv.conf. If you're looking at # /etc/resolv.conf and seeing this text, you have followed the symlink. # # This is a dynamic resolv.conf file for connecting local clients directly to # all known uplink DNS servers. This file lists all configured search domains. # # Third party programs should typically not access this file directly, but only # through the symlink at /etc/resolv.conf.

nameserver只有192.168.3.1证明没有生效，得修改
root@amicore:/etc# rm -f resolv.conf root@amicore:/etc# sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf
再次查看，竟然还是没有生效，reboot服务器吧！
生效后文件内容如下

4、再次用docker-compose启动容器
先前的安装是失败了的，重新运行
docker-compose up -d
发现成功了
