一、报错发现
使用docker pull或者docker run时，从hub库中拉取下载镜像时报错，具体如下：
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).See 'docker run --help'.
问题是因为docker镜像源无法连接的问题，需要配置国内的docker源
二、解决方式
1、Linux操作系统
① 修改配置文件 /etc/docker/daemon.json，大力出奇迹，修改后内容如下：都加！都加！不信没一个可以用的
{ "runtimes": { "nvidia": { "args": [], "path": "nvidia-container-runtime" } }, "registry-mirrors": [ "https://registry.docker-cn.com", "http://hub-mirror.c.163.com", "https://docker.mirrors.ustc.edu.cn", "https://cr.console.aliyun.com", "https://mirror.ccs.tencentyun.com", "https://registry.docker-cn.com", "http://hub-mirror.c.163.com", "https://docker.mirrors.ustc.edu.cn/", "https://yxzrazem.mirror.aliyuncs.com", "https://docker.kubesre.xyz", "https://dc.j8.work", "https://docker.registry.cyou", "https://docker.hlyun.org", "https://docker.chenby.cn", "https://docker.jsdelivr.fyi", "https://docker-mirrors.mjjman.com", "https://docker.kubesre.xyz", "https://huecker.io", "https://dockerhub.timeweb.cloud", "https://docker.registry.cyou", "https://docker-cf.registry.cyou", "https://dockercf.jsdelivr.fyi", "https://dockertest.jsdelivr.fyi", "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" ], "insecure-registries": [], "debug": false, "experimental": false, "features": { "buildkit": true }, "builder": { "gc": { "enabled": true, "defaultKeepStorage": "20GB" } }}
② 修改后配置文件，重启docker服务，命令如下：
[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl restart docker
