docker compose uwsgi connect（）失败（111:连接被拒绝）

我和docker做了infra

还使用docker compose对每个容器进行整理

下面是我使用的图片

• nginx：最新版本
• mongo：最新的
• python:3.6.5

为了部署flask Web服务器，我使用了uwsgi

（uwsgi安装在python:3.6.5）

[docker compose.yml]

version: '3.7'

services:
  nginx:
    build: 
      context: .
      dockerfile: docker/nginx/dockerfile
    container_name: nginx
    hostname: nginx-dev
    ports:
      - '80:80'
    networks: 
      - backend
    links:
      - web_project

  mongodb:
    build:
      context: .
      dockerfile: docker/mongodb/dockerfile
    container_name: mongodb
    hostname: mongodb-dev
    ports:

定义的

套接字=：5000

在建立/建立和访问网站后，它向控制台抛出502坏网关抛出错误

nginx | 2018/11/12 06:28:55[错误]6#6:*1 connect（）在连接到上游时失败（111:连接被拒绝），客户端：172.27.0.1，服务器：，请求：“GET/HTTP/1.1”，上游：uwsgi://172.27.0.3:5000，主机：“localhost”

我在谷歌搜索了很长时间，但我找不到解决方案

这里有什么解决办法吗

谢谢。

您必须在Python应用程序中公开端口5000

FROM python:3.6.5

COPY . ./home
WORKDIR home
RUN pip install -r app/requirements.txt
RUN apt-get update && apt-get install -y uwsgi-plugin-python
EXPOSE 5000 # <---- add this
RUN uwsgi --ini config/uwsgi.ini

来自python:3.6.5的

复制/家

运行pip安装-r app/requirements.txt
运行apt-get-update&&apt-get-install-y uwsgi-plugin-python
曝光5000#
