如何设置充当代理的Docker注册表？ [英] How to set-up a docker registry acting as a Proxy?

问题描述

我有一台服务器（我们将其命名为A），该服务器可以访问互联网，并且可以从该服务器上从docker.io注册表中提取图像。

I have a server (let's name it A) which may have access to internet and from which I'm able to pull images from the officiel docker.io registry.

我还有其他服务器（B，C），出于安全原因不能具有相同的访问权限，但可以访问A。

I also have other servers (B, C) which cannot have this same access for security reasons, but are allowed to have access to A.

我还决定在A上安装一个私有注册表，可以在B和C上使用它。

I also have decided to install a private registry on A, which can be used from B and C.

是否有可能让该注册表充当代理，所以当我想要从B获取正式图像，可以通过A完成吗？

Is it possible to have this registry acting as a proxy, in the way that when I want to pull an official image from B, it could be done through A ?

推荐答案

同时，这可能是这样的：

但是Pu不支持使用这种注册表：

But Pushing to such a registry is not supported:
