docker pull 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)

使用魔法：

[root@rancher docker]# docker pull rancher/rancher:v2.7.5
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)

emmm魔法

sudo mkdir -p /etc/systemd/system/docker.service.d
sudo cat >/etc/systemd/system/docker.service.d/http-proxy.conf << EOF
Environment="HTTP_PROXY=http://proxy.example.com:8080/"
Environment="HTTPS_PROXY=http://proxy.example.com:8080/"
Environment="NO_PROXY=localhost,127.0.0.1,.example.com"
EOF

这里使用的是自己的clash for windows .

http://proxy.example.com

使用本地的ip地址。默认端口使用的7890

可以自行更改

注意这里的proxy-ip地址使用的是自己所联网的ip地址那张网卡联网就用那个ip.
