      "base" : "10.0.1.0/16",
      "size" : 24
    }
   ],
    "registry-mirrors": [
        "https://docker-0.unsee.tech",
        "https://docker.1ms.run",
        "https://docker.xuanyuan.me",
        "https://0vrv861z.mirror.aliyuncs.com",
        "http://hub-mirror.c.163.com",
        "https://docker.mirrors.ustc.edu.cn",
        "https://registry.docker-cn.com",
        "https://2a6bf1988cb6428c877f723ec7530dbc.mirror.swr.myhuaweicloud.com",
        "https://docker.m.daocloud.io",
        "https://hub-mirror.c.163.com",
        "https://mirror.baidubce.com",
        "https://your_preferred_mirror",
        "https://dockerhub.icu",
        "https://docker.registry.cyou",
        "https://docker-cf.registry.cyou",
        "https://dockercf.jsdelivr.fyi",
        "https://docker.jsdelivr.fyi",
        "https://dockertest.jsdelivr.fyi",
        "https://mirror.aliyuncs.com",
        "https://dockerproxy.com",
        "https://mirror.baidubce.com",
        "https://docker.m.daocloud.io",
        "https://docker.nju.edu.cn",
        "https://docker.mirrors.sjtug.sjtu.edu.cn",
        "https://docker.mirrors.ustc.edu.cn",
        "https://mirror.iscas.ac.cn",
        "https://docker.rainbond.cc"
      ]
}

7. 测试docker

重点：如果systemctl命令不可用，可以使用service命令

# 启动docker
systemctl start docker
 
# 停止docker
systemctl stop docker 
 
# 重启docker
systemctl restart  docker

# 配置开机自启
systemctl enable docker

# 查看docker版本
docker -v

# 查看docker是否启动
service docker status

# 启动docker服务
service docker start

# 停止docker服务
service docker stop

# 重启docker服务
service docker restart

# 查看所有服务
service --status-all
