docker-ce 19.03.5 在尝试启动从 docker hub 抓取图像的容器时不会使用代理答案

【问题标题】：docker-ce 19.03.5 won't use proxy when trying to start a container that grabs an image from docker hubdocker-ce 19.03.5 在尝试启动从 docker hub 抓取图像的容器时不会使用代理

【问题描述】：

预期行为 I would expect to see traffic trying to hit my proxy server when docker grabs images from docker hub.

实际行为 I see traffic trying to go directly to docker hub and is not using the proxy specified in the environment variable

重现行为的步骤设置代理变量并确保它设置为： echo $HTTP_PROXY 通过指定 HTTP_PROXY 变量尝试使用 golang 运行容器 docker run -e HTTP_PROXY golang:1.9

我也尝试通过在此处创建文件来设置 systemd 配置： /etc/systemd/system/docker.service.d/http-proxy.conf 然后运行 systemctl daemon-reload 然后 service docker restart

【解决方案1】：

我从 systemd http-proxy.conf 文件中删除了 HTTPS_PROXY 设置并修复了它，显然我的代理不支持 tls 连接，所以我不需要 HTTP_PROXY 和 HTTPS_PROXY
