问题描述

$ docker pull nginx                                                                                                                    130 ↵

解决方法

因为在 /etc/systemd/system/docker.service.d/http-proxy.conf 添加了 HTTPS_PROXY, 导致链接被代理中转了,代理又是无效的链接.

去掉 HTTPS_PROXY 即可.

[Service]    
Environment="NO_PROXY=localhost,127.0.0.1,0.0.0.0"

重启docker, sudo systemctl restart docker.service

$ docker pull nginx

说明: docker.service.d/http-proxy.conf文件是手动创建的.docker不会帮你创建, 所以坑还是自己挖的.
