部署在Docker容器中的Nginx不会暴露部署在另一个Docker容器中的nuxtjs(502 Bad Gateway) [英] Nginx deployed in docker container doesn't expose nuxtjs deployed in another docker container (502 Bad Gateway)

问题描述

我正在尝试使用nginx作为docker容器中的代理服务器运行nuxtjs应用程序.所以，我有2个容器:nginx和nuxt

I'm trying to run nuxtjs application using nginx as proxy server in docker containers. So, I have 2 containers: nginx and nuxt

这是我构建nuxt应用程序的方式

here is how I'm building nuxt application

FROM node:11.15
ENV APP_ROOT /src
RUN mkdir ${APP_ROOT}
WORKDIR ${APP_ROOT}
ADD . ${APP_ROOT}
RUN npm install
RUN npm run build
ENV host 0.0.0.0

结果似乎很好

接下来是nginx配置

Next is nginx config

server {
  listen 80;
  server_name dev.iceik.com.ua;

  location / {
      proxy_pass http://nuxt:3000;
      proxy_set_header Host $host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}

我也尝试过这种nginx配置

Also I've tried this nginx config

upstream nuxt {
  server nuxt:3000;
}
server {
  listen 80;
  server_name dev.iceik.com.ua;

  location / {
      proxy_pass http://nuxt;
      proxy_set_header Host $host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}

最后是我的docker-compose文件

And finally my docker-compose file

version: "3"

services:
  nuxt:
    build: ./app/
    container_name: nuxt
    restart: always
    ports:
      - "3000:3000"
    command:
      "npm run start"

  nginx:
    image: nginx:1.17
    container_name: nginx
    ports:
      - "80:80"
    volumes:
      - ./nginx:/etc/nginx/conf.d
    depends_on:
      - nuxt

我可以从Nginx容器ping Nuxt容器

I can ping nuxt container from nginx container

这里也是打开的端口

因此，预期结果是我可以访问我的nuxt应用程序.但是我收到502 Bad Gateway

So, the expected result is that I can access my nuxt application. However I'm getting 502 Bad Gateway

您有什么想法，为什么nginx不公开我的nuxt应用程序?

Do you have any ideas why nginx doesn't expose my nuxt application?

谢谢您的任何建议！

推荐答案

Nodejs被暴露为 localhost:3000 而不是 0.0.0.0:3000

Nodejs is exposed localhost:3000 instead of 0.0.0.0:3000

请更正它.会工作
