1, docker 拉镜像报错

dart 复制代码

#docker pull centos:latest
Error response from daemon: Get "https://registry-1.docker.io/v2/": context deadline exceeded**加粗样式**

这个错误表明Docker客户端尝试访问Docker Hub或其他Docker注册中心时出现了问题。具体来说，是在尝试获取注册中心API的响应时遇到了错误。可能的原因包括网络问题、认证问题、注册中心URL不正确或者注册中心服务本身不可用

解决方法

dart 复制代码

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

追加

dart 复制代码

{
  "registry-mirrors" : ["https://docker.registry.cyou",
"https://docker-cf.registry.cyou",
"https://dockercf.jsdelivr.fyi",
"https://docker.jsdelivr.fyi",

重载和重启dockers服务

sudo systemctl restart docker
