1.创建/etc/docker目录

sudo mkdir -p /etc/docker

2.创建docker镜像配置文件

sudo tee /etc/docker/daemon.json <<-'EOF'

 {
  "registry-mirrors": [
          "https://ox288s4f.mirror.aliyuncs.com",
          "https://registry.docker-cn.com",
          "http://hub-mirror.c.163.com",
          "https://mirror.ccs.tencentyun.com"
