如何使用 nginx docker 容器访问本地主机上的服务器? [英] How do I access a server on localhost with nginx docker container?

问题描述

我正在尝试使用 nginx 的 dockerized 版本作为我的节点 (ExpressJS) 应用程序的代理服务器.无需对 nginx 进行任何配置并为容器发布端口 80，我就可以看到默认的 nginx 登陆页面.所以我知道很多都在起作用.

I'm trying to use a dockerized version of nginx as a proxy server for my node (ExpressJS) application. Without any configuration to nginx and publishing port 80 for the container, I am able to see the default nginx landing page. So I know that much is working.

现在我可以挂载包含 proxy_pass localhost:3000 配置的启用站点的目录.我的节点应用程序在本地运行(不在任何 Docker 容器中)，我可以通过端口 3000(即 localhost:3000)访问它.但是，我假设在 nginx 容器运行、映射到端口 80 并代理我的 localhost:3000 的情况下，我将能够看到我的非常简单(hello world)应用程序.相反，我收到了 502.

Now I can mount my sites-enabled directory that contains the configuration for proxy_pass localhost:3000. I have my node application running locally (not in any Docker container) and I can access it via port 3000 (i.e. localhost:3000). However, I would assume that with nginx container running, mapped to port 80, and proxying my localhost:3000, that I would be able to see my very simple (hello world) application. Instead I receive a 502.

我需要向 docker 传递一些东西吗?这可能是 nginx 配置错误吗?这是我的 nginx 配置:

Do I need to pass something into docker? Is this likely a nginx configuration error? Here is my nginx configuration:

server {
  listen 0.0.0.0:80;
  server_name localhost;

  location / {
    proxy_pass http://localhost:3000;
  }
}

我尝试使用 这个问题 但它似乎没有帮助.除非我做错了什么.

I have tried using this question but it did not seem to help. That is unless I'm doing something completely wrong.

推荐答案

您可以获取如图所示的当前 IP 地址 此处:

You can get your current IP address as shown here:

ifconfig en0 | grep inet | grep -v inet6 | awk '{print $2}'

然后你可以在 docker run 中使用 --add-host 标志:

Then you can use the --add-host flag with docker run:

docker run --add-host localnode:$(ifconfig en0 | grep inet | grep -v inet6 | awk '{print $2}') ...

在您的 proxypass 中使用 localnode 而不是 localhost.

In your proxypass use localnode instead of localhost.
