NGINX 代理多个容器？

[Steve_Gaarder]

在本主题中：

Multiple Discourses, multiple containers, one server

Despite at least one reference which purports to describe the process I found it very difficult to work out how to run multiple Discourse instances on the same hosting infrastructure (using an instance of nginx running on the host to proxy the Discourse instances). Apparently there’s a way to run Discourse in a “multisite” mode, with multiple instances from a single code installation, but I have not yet seen a real description of how that works. I’ve gone the route of two independent code inst…

作者讨论了使用一个数据容器配合多个 Web 容器的方案。他们通过不同的端口将流量导向正确的容器。我考虑采用类似的方法，但使用 Nginx 代理根据请求的主机名来转发流量。不过，每个 Web 容器前面都已有自己的 Nginx 代理来代理 Rails，两层代理似乎不太妥当。是否可以让主机上的 Nginx 安装直接进行代理，并直接与每个 Web 容器中的 Rails 通信，从而绕过它们各自的代理？
