作者：return（b,a％b）；
文章讨论了Docker客户端访问DockerHub或其他注册中心时遇到的错误,并提供了五种解决方法,包括检查网络、docker状态、更换源、重载和重启Docker服务以及重新执行docker pull hello-world命令
docker拉取失败,更换docker的源
docker pull hello-world时报错 hh@hh-virtual-machine:~$ docker pull hello-world Using default tag: latest Error response from daemon: Get "https://registry-1.docker.io/v2/": context deadline exceeded hh@hh-virtual-machine:~$ docker pull registry.cn-hangzhou.aliyuncs.com/library/ubuntu:22.04 Error response from daemon: pull access denied for registry.cn-hangzhou.aliyuncs.com/library/ubuntu, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
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
检查网络
hh@hh-virtual-machine:~$ ping www.baidu.com PING www.wshifen.com (119.63.197.151) 56(84) bytes of data. 64 bytes from 119.63.197.151 (119.63.197.151): icmp_seq=1 ttl=49 time=161 ms 64 bytes from 119.63.197.151 (119.63.197.151): icmp_seq=2 ttl=49 time=164 ms 64 bytes from 119.63.197.151 (119.63.197.151): icmp_seq=3 ttl=49 time=160 ms ^C --- www.wshifen.com ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 160.431/161.615/163.762/1.520 ms
检查docker状态
hh@hh-virtual-machine:~$ systemctl status docker

更换源
systemctl status docker
sudo mkdir -p /etc/docker
vim /etc/docker/daemon.json
添加：
{
"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",

],
"insecure-registries" : [
"registry.docker-cn.com",
"docker.mirrors.ustc.edu.cn"
],
"debug": true,
"experimental": false
}
重载和重启dockers服务
sudo systemctl daemon-reload sudo systemctl restart docker docker info
重新执行
docker pull hello-world
