docker pull命令拉取镜像失败的解决方案

一、执行docker pull命令，拉取镜像失败

报错信息：error pulling image configuration: Get https://production.cloudflare.docker.com/registry-v2/docker/registry/v2/blobs/sha256/51/5107333e08a87b836d48ff7528b1e84b9c86781cc9f1748bbc1b8c42a870d933/data?verify=1725414357-z%2BnaVrrs0%2Fi0D3ixKDH8JHhJgUQ%3D: dial tcp 88.191.249.182:443: i/o timeout

二、解决方案

解决的步骤如下：

1. 打开daemon.json文件

vim /etc/docker/daemon.json

2. 将其镜像地址进行替换

{
"registry-mirrors": [
    "https://docker.m.daocloud.io",
    "https://dockerproxy.com",
    "https://registry.docker-cn.com",
    "https://docker.mirrors.ustc.edu.cn",
    "https://hub-mirror.c.163.com",
    "https://hub.uuuadc.top",
    "https://docker.anyhub.us.kg",
    "https://dockerhub.jobcher.com",
    "https://dockerhub.icu",
    "https://docker.ckyl.me",
    "https://docker.awsl9527.cn",
    "https://mirror.baidubce.com"
  ]
}

三、重启docker服务

systemctl daemon-reload
systemctl restart docker
