15-docker 配置dns

1.配置容器dns文件，/etc/docker/daemon.json

[root@docker03 opt]# vim /etc/docker/daemon.json 
{
  "registry-mirrors": ["https://de378wx8.mirror.aliyuncs.com"],
  "dns": [
    "223.5.5.5",
    "223.6.6.6"
  ]
}

2.容器查看

[root@docker03 ~]# docker run -it --rm --name nginx05 sunmmi/nginx 
[root@22e433dd6425 /]# cat /etc/resolv.conf 
nameserver 223.5.5.5
nameserver 223.6.6.6
