Flask in Docker (served with Gunicorn through Nginx)

Simple boilerplate to get a flask app up and running in Docker using Docker Compose, and served with a Gunicorn HTTP server through Nginx proxy. No HTTPS or HTTP/2 (yet). The hot reload of flask in development mode it still working even if running in a Docker container, served with Gunicorn through Nginx. (Still detects changes to route.py and will reload server upon saving this file)

Tech used in this project:

• Docker 2.0.0.3 (Container magement system)
• Docker-compose 1.23.2 (Container magement system)
• Flask 1.0.2 (Micro framework)
• Gunicorn 19.9.0 (Application server)
• Nginx 1.15.8
• Python 3.6.7 (Language)
• Python-dotenv 0.10.1 (Easier environment control in .flaskenv)

How to get up and running in development mode:

• git clone or download this repo.
• Download and install Docker(Docker-compose comes with docker desktop, so no need to install this individually)
• Build and start the app: docker-compose up --build -d (-d to run in background use docker-compose down to stop)

The app is now running in development mode from your local ip. ex. 192.168.1.123

To run in production mode:

• Edit the .flaskenv file to say: FLASK_ENV=production
• Remove the --reload from the run command in the docker-compose.yml

The app is now running in production mode from your local ip. ex. 192.168.1.123

You can now choose to deploy to a server if you like.

Disclamer❗️

I am NOT a professional devops engineer, developer or alike❗️ Take this repo with a grain of salt.

This is by no means a "how to deploy and run a production website" kind of repo❗️ I take no responsibility for the use of this repo in production if choosen to do so❗️ There are no security in place for this app other than the built in stuff in the framworks, servers and containers❗️

Other than that, you are free to clone or fork this repo as you wish❗️

Happy coding 💻
