执行docker run命令时报错Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

一.解决办法: 修改host

二.步骤如下

  2.1 安装dig工具

     sudo apt-get install dnsutils -y (ubuntu下的安装方法)

  2.2 找到registry-1.docker.io对应的ip地址    

    jello$ dig @8.8.8.8 registry-1.docker.io

    ; <<>> DiG 8.8 hello <<>> @8.8.8.8 registry-1.docker.io
    ; (1 server found)
    ;; global options: +cmd
    ;; Got answer:

    registry-1.docker.io. 40 IN A 52.22.201.61
    registry-1.docker.io. 40 IN A 34.232.31.24

    ;; MSG SIZE rcvd: 177

  2.3 修改hosts表

    echo 34.233.151.211 registry-1.docker.io > /etc/hosts

补充:

  方法二:添加dns 8.8.8.8

    a 将nameserver 8.8.8.8写入/etc/resolvconf/resolv.conf.d/head文件中

      sudo vi /etc/resolvconf/resolv.conf.d/head

    b 更新dns

      sudo resolvconf -u

  方法三:修改镜像源

    a sudo vi /etc/docker/daemon.json

      写入以下内容:     

{
    "registry-mirrors":["https://docker.mirrors.ustc.edu.cn"]
}

 

    b 重新加载docker的配置文件

      sudo systemctl daemon-reload

    c 重启docker

      sudo systemctl restart docker

 

  方法四: 设置代理(需要设置代理才能访问外网)

    a ubuntu上设置代理(添加代理配置到对应配置文件)

    $ cat /etc/systemd/system/docker.service.d/http-proxy.conf

    [Service]
    Environment="HTTP_PROXY=http://USERNAME:PASSWORD@PROXYIP:PROXYPORT" (请根据自己的情况替换用户名,密码,代理服务器ip和代理端口)
    Environment="HTTPS_PROXY=http://USERNAME:PASSWORD@PROXYIP:PROXYPORT" (请根据自己的情况替换用户名,密码,代理服务器ip和代理端口)
    Environment="NO_PROXY=localhost,127.0.0.1,docker-registry.example.com,.corp" (请根据自己的情况替换)
    注意: 如果用户名或密码中有特殊符号,请使用%+ascii来替换,比如说用户名中有#字符,那么使用%23来代替#
    b 使配置生效
    $ sudo systemctl daemon-reload
    $ sudo systemctl restart docker
    c 检查代理是否生效
    $ sudo docker info | grep Proxy
    HTTP Proxy: http://xxxxx:xxxxx@PROXYIP:PORT
    HTTPS Proxy: http://xxxxx:xxxxx@PROXYIP:PORT
    No Proxy: localhost,127.0.0.1,docker-registry.example.com,.corp"
