Docker启动容器时，拉取镜像失败 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)

在Linux Ubuntu服务器中部署，启动容器时报错：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)

解决方法：

1、确认网络连接正常：

ping www.baidu.com

2、确认docker服务是否正常

systemctl status docker

3、以上都正常可以尝试更换镜像源的问题；

添加的daemon.json文件（没有就新增）

root# cat /etc/docker/daemon.json
{
  "registry-mirrors" : ["https://docker.registry.cyou",
"https://docker-cf.registry.cyou",
"https://dockercf.jsdelivr.fyi",
"https://docker.jsdelivr.fyi",

],
 "insecure-registries" : [
    "registry.docker-cn.com",
    "docker.mirrors.ustc.edu.cn"
    ],
"debug": true,
"experimental": false
}

4、重载生效

sudo systemctl daemon-reload

5、重启服务

sudo systemctl restart docker

6、重新执行

docker-compose up -d

等拉取镜像完成，容器启动成功
