docker拉取镜像时报：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)错误解决办法！
说明
原本是要拉取rabbitmq的镜像，但是一连试了好几种方式好像都不行，尝试查找验证各种方案，修改hosts文件等都不行，也尝试使用修改过daemon.json文件，但最终还是报这个错，就在最后发现了一位大佬的笔记，抱着试试的心态尝试了一下大佬的解决方案，没有想到最后成功解决了，感谢这位大佬，这里贴一下大佬的笔记：
https://blog.csdn.net/qq_28809683/article/details/143110434
1、docker版本说明
Docker version 26.1.4, build 5650f9b
2、错误说明
[root@VM-20-6-centos docker]# docker pull rabbitmq:3.9.13-management
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)
3、解决办法
3.1、进入/etc/docker目录下，修改daemon.json文件
特别说明，一般安装docker的时候如果配置了这个文件，这个文件是会存在的，如果不存在也没有关系，直接新建一个daemon.json文件也是可以的，但是记得给权限就行，
[root@VM-20-6-centos docker]# vi daemon.json
然后将以下内容粘贴进daemon.json文件中，保存退出。
{"registry-mirrors": ["https://docker.1panelproxy.com"]
}
重点是这个镜像仓库：https://docker.1panelproxy.com,因此里面只需要保存这个镜像仓库地址即可
以下是我的daemon.json，仅供参考！
{"registry-mirrors": ["https://docker.1panelproxy.com","https://2m11665s.mirror.aliyuncs.com","https://registry.docker-cn.com","https://dockerhub.azk8s.cn","https://docker.mirrors.ustc.edu.cn","http://hub-mirror.c.163.com","https://k8s.gcr.io","https://github-releases.githubusercontent.com","https://ustc-edu-cn.mirror.aliyuncs.com"],"insecure-registries": ["registry.me:5000","http://docker.mirrors.ustc.edu.cn","https://k8s.gcr.io","https://github-releases.githubusercontent.com","https://registry-1.docker.io","decs.com"],"exec-opts": ["native.cgroupdriver=systemd"]
}
3.2、修改保存完daemon.json文件后，重启一下docker,执行以下两条命令即可
[root@VM-20-6-centos docker]# systemctl daemon-reload
[root@VM-20-6-centos docker]# systemctl restart docker
最后验证一下是否可以拉取想要的镜像
[root@VM-20-6-centos docker]# docker pull rabbitmq:3.9.13-management
3.9.13-management: Pulling from library/rabbitmq
4d32b49e2995: Pull complete
2108a18330ce: Pull complete

Status: Downloaded newer image for rabbitmq:3.9.13-management
docker.io/library/rabbitmq:3.9.13-management
发现可以正常拉取
3.3、如果是需要在安装时指定，可执行以下命令
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{"registry-mirrors": ["https://docker.1panelproxy.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
效果是和上面一样的
4、写在最后
4.1、在排查这个错误的过程中，发现了几个好玩的命令的，记录一下
journalctl：查看docker.service的运行过程及日志信息
[root@VM-20-6-centos docker]# journalctl -u docker.service
