玩弄 Flask 我想在 docker 中进行真正的设置并运行。这意味着 Flask 应通过 nginx 和 Gunicorn 提供服务。我设置了一个示例代码存储库https://github.com/geoHeil/pythonServing https://github.com/geoHeil/pythonServing但到目前为止还无法让nginx正常工作。
烧瓶供应于application:5000
,docker 应该将应用程序解析为其各自的名称。
Nginx配置如下:
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;
}
}
这对我来说看起来不错。到目前为止我还找不到问题所在。

撰写文件在这里。启动命令是
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"
Your nginx配置文件位于错误的位置。
修复步骤:
sudo docker-compose down
删除 nginx 镜像:
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nginxDockerfile:
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。
现在尝试这个 docker-compose 文件(使用用户定义的网络):
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:
并调出容器:
sudo docker-compose up
浏览至http://本地主机:8880 http://localhost:8880
