docker配置镜像Docker pull时报错：https://registry-1.docker.io/v2/

docker run hello-world时报错
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": read tcp 192.168.30.91:51536->44.208.254.194:443: read: connection reset by peer.

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。

2、解决方法

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",

 "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 run hello-world
