Compose sample application
Python/Flask application with Nginx proxy and a Mongo database
Project structure:
.
├── docker-compose.yaml
├── flask
│ ├── Dockerfile
│ ├── requirements.txt
│ └── server.py
└── nginx
└── nginx.conf
services:
web:
build: app
ports:
- 80:80
backend:
build: flask
...
mongo:
image: mongo
The compose file defines an application with three services web, backend and db.
When deploying the application, docker-compose maps port 80 of the web service container to port 80 of the host as specified in the file.
Make sure port 80 on the host is not being used by another container, otherwise the port should be changed.
Deploy with docker-compose
$ docker-compose up -d

Expected result
Listing containers must show three containers running and the port mapping as below:
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
a0f4ebe686ff nginx "/bin/bash -c 'envsu…" About a minute ago Up About a minute 0.0.0.0:80->80/tcp nginx-flask-mongo_web_1

d7eea5481c77 mongo "docker-entrypoint.s…" About a minute ago Up About a minute 27017/tcp nginx-flask-mongo_mongo_1
After the application starts, navigate to http://localhost:80 in your web browser or run:
$ curl localhost:80
Hello fom the MongoDB client!
Stop and remove the containers
$ docker-compose down
