Docker pull 报错 registry-1.docker.io 超时解决方案

2.2、检查 Docker 服务状态

运行 systemctl status docker（Linux 系统）查看 Docker 服务是否正在运行。

root@ubuntu-database:/opt/dify/docker# systemctl status docker
● docker.service - Docker Application Container Engine
 Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; preset: enabled)
 Active: active (running) since Wed 2024-11-27 12:04:05 UTC; 55min ago
 TriggeredBy: ● docker.socket
 Docs: https://docs.docker.com
 Main PID: 4766 (dockerd)
 Tasks: 10 Memory: 21.8M (peak: 24.5M) CPU: 479ms CGroup: /system.slice/docker.service

如以上都没有问题，下面考虑 Docker 换源。

2.3、换源

创建目录并编辑配置文件：

sudo mkdir -p /etc/docker
vim /etc/docker/daemon.json

在 /etc/docker/daemon.json 文件中加入以下配置：

{
  "registry-mirrors": [
    "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",
    "https://do.nark.eu.org",
    "https://dc.j8.work",
    "https://gst6rzl9.mirror.aliyuncs.com",
    "https://registry.docker-cn.com",
    "http://hub-mirror.c.163.com",
    "http://mirrors.ustc.edu.cn/",
    "https://mirrors.tuna.tsinghua.edu.cn/",
    "http://mirrors.sohu.com/"
  ],
  "insecure-registries": [
    "registry.docker-cn.com",
    "docker.mirrors.ustc.edu.cn"
  ],
  "debug": true,
  "experimental": false
}

重载配置生效：

sudo systemctl daemon-reload

重启服务：

sudo systemctl restart docker

查看是否配置成功：

docker info

输出示例：

root@ubuntu-database:/etc/docker# docker info
Client:
 Version: 27.3.1
Server:
 Server Version: 27.3.1
 Registry Mirrors:
  https://docker.registry.cyou/
  https://docker-cf.registry.cyou/
  ...
  http://mirrors.sohu.com/
...

重新执行 docker compose up -d，若出现正常启动日志，说明问题已解决。
