在docker中通过nginx和gunicorn服务烧瓶

问题描述：

玩烧瓶，我想建立一个真正的设置并在docker中运行.这意味着应通过Nginx和Gunicorn来盛装烧瓶.我设置了一个示例代码存储库 https://github.com/geoHeil/pythonServing ，但到目前为止可以不能让Nginx正常工作.

Playing around with flask I would like to get a real setup up and running in docker. This means flask should be served via nginx and gunicorn. I set up a sample code repository https://github.com/geoHeil/pythonServing but so far can't get nginx to work properly.

烧瓶在application:5000上提供服务，码头工人应将应用程序解析为其各自的名称.

Flask is served on application:5000, docker should resolve application to its respective name.

Nginx的配置如下:

Nginx config is as follows:

server {

    listen 8080;
    server_name application;
    charset utf-8;

    location / {
        proxy_pass http://application:5000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

对我来说看起来不错.到目前为止，我找不到问题.

which looks good to me. So far I cant find the problem.

撰写文件在这里.启动命令是

compose file is here. Command to start was

docker-compose build
docker-compose up

version: '2'
services:
  application:
    restart: always
    build: ./application
    command: gunicorn -w 4 --bind :5000 wsgi:application
    links:
      - db
    expose:
     - "5000"
    ports:
      - "5000:5000"
  nginx:
    restart: always
    build: ./nginx
    links:
      - application
    expose:
      - 8080
    ports:
      - "8880:8080"

答

您的 nginx 配置文件位于错误的位置.

Your nginx config file is in a wrong location.

修复步骤:

sudo docker-compose down

删除nginx图片:

sudo docker images
sudo docker rmi 
REPOSITORY                       TAG                 IMAGE ID            CREATED              SIZE
pythonserving_nginx              latest              152698f13c7a        About a minute ago   54.3 MB

sudo docker rmi pythonserving_nginx

现在更改nginx Dockerfile :

Now change the nginx Dockerfile:

FROM nginx:1.11.8-alpine
MAINTAINER geoheil

ADD sites-enabled.conf /etc/nginx/conf.d/sites-enabled.conf

请注意nginx配置的位置.

Please note the location of nginx config.

现在尝试使用此docker-compose文件(使用用户定义的网络):

Now try this docker-compose file (Using User-defined Networks):

version: '2'
services:
  application:
    restart: always
    build: ./application
    command: gunicorn -w 4 --bind :5000 wsgi:application
    networks:
      - testnetwork
    expose:
     - "5000"
    ports:
      - "5000:5000"
  db:
    restart: always
    image: postgres:9.6.1-alpine
    networks:
      - testnetwork
    ports:
      - "5432:5432"
    environment:
      - POSTGRES_USER=d
      - POSTGRES_PASSWORD=d
      - POSTGRES_DB=d
    volumes:
      - ./postgres:/var/lib/postgresql
  nginx:
    restart: always
    build: ./nginx
    networks:
      - testnetwork
    expose:
      - 8080
    ports:
      - "8880:8080"
networks:
  testnetwork:

然后拿起容器:

sudo docker-compose up

浏览到 http://localhost:8880
