设置HTTP/HTTPS 代理

1. 创建 docker.service.d 目录

mkdir -p /etc/systemd/system/docker.service.d

2. 创建HTTP 或者HTTPS 代理文件

# HTTP：
vim /etc/systemd/system/docker.service.d/http-proxy.conf

[Service]
Environment="HTTP_PROXY=xxx.xxx.xxx.xxx:443" "NO_PROXY=localhost,127.0.0.1,xxx.xxxxxx:5000"

# HTTPS：
vim /etc/systemd/system/docker.service.d/http-proxy.conf

[Service]
Environment="HTTPS_PROXY=xxx.xxx.xxx.xxx:443" "NO_PROXY=localhost,127.0.0.1,xxx.xxxxxx:5000"

3、完成修改后保存/刷新

systemctl daemon-reload
systemctl restart docker

4、查看修改结果

systemctl show --property=Environment docker

Environment=HTTPS_PROXY=xxx.xxx.xxx.xxx:443 NO_PROXY=localhost,127.0.0.1,mydocker-registry.com:5000
