尝试在 RHEL 7,7 上安装 docker-ce。 - 添加回购协议时无法访问网络？

Question

我全新安装了 RHEL 7.7。我正在尝试安装 docker-ce。当我尝试添加 docker 存储库时，我得到了网络无法访问的错误消息，但我可以毫无问题地获取存储库文件。我已启用 HTTP_PROXY、HTTPS_PROXY 和 FTP_PROXY 从该主机访问互联网。

知道为什么会这样吗？

我的尝试：

如果我尝试在未启用代理的情况下获取回购文件：

Answer 1

好吧...我设法解决了这个问题，但我不明白为什么它会起作用...

我将我的 http 代理添加到 yum.conf 文件，现在我可以添加存储库并从那里继续。

环境中的 http 代理不应该对 yum 足够好吗？
