ubuntu docker pull 失败 Error response from daemon: Get https://registry-1.docker.io/v2/

问题：

ubuntu@VM-3-4-ubuntu:~$ docker pull tensorflow/tensorflow:2.3.4-gpu
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)

 

方案1  ---最后生效了，因为用的腾讯云的服务器，之前添加的都没用，直到添加了腾讯云镜像地址。。。

修改/etc/docker/daemon.json文件，并重启docker服务

{    registry-mirrors: [https://registry.docker-cn.com,http://hub-mirror.c.163.com,https://mirror.ccs.tencentyun.com]  }

方案2 改后未生效，但操作过的

修改/etc/resolv.conf 文件 并重启docker服务

添加内容：

nameserver 8.8.8.8
nameserver 8.8.4.4

 

以上方案均需要执行

ubuntu@VM-3-4-ubuntu:/etc/docker$ sudo systemctl daemon-reload
ubuntu@VM-3-4-ubuntu:/etc/docker$ sudo systemctl restart docker

镜像拉取和服务器网络状态有关系
