1. 修改配置

vim /etc/docker/daemon.json


#修改自己镜像加速地址
{
 "registry-mirrors": [
    "镜像加速地址"
  ],
 "exec-opts": ["native.cgroupdriver=systemd"],
 "max-concurrent-downloads": 10,
 "max-concurrent-uploads": 5,
 "log-opts": {
   "max-size": "300m",
   "max-file": "2"
 },
 "live-restore": true
}

2. 使配置生效

systemctl daemon-reload
systemctl restart docker
