Kieran7741 / base_flask_mongo_app

Basic docker-compose Flask app with a MongoDb instance

Run Flask and MongoDB using docker-compose

When dealing with multi container applications you should define the application in a docker-compose.yml file. This file defines how the different componets of the app should be run and how they interact.

App components

The app uses a web and db container. The web container runs the Flask webserver while the db container runs MongoDB.

Note: build . indicates that the DockerFile in the current directory should be used to build the image.

    build: .
