Template app with Flask, Postgres, Gunicorn and Docker

Flask template app

Simple Flask app with Gunicorn and Docker.

Implements the basics I constantly keep re-inventing for Flask based apps:

1. Package structure
2. Developing with Flask builtin server while in Docker
3. PostgreSQL and psycopg2 (ORM is not needed, mkey..)
4. Blueprints
5. Flask-Restful for API's
6. Bootstrap base template and static files

Database

I don't really believe in ORMs, so plain old SQL it is. PostgreSQL is also a bit nicer to work with than MySQL, the only pain being getting psycopg2 installed to Alpine based docker image. Database root and application user credentials can be found in docker-compose.yml.

Build, install, run

docker build -t kerma/flask-template-app .
docker-compose up

You can skip build step if you have devpi-server running on localhost:3141. After Postgres has booted itself run (password: flask):

sh script/bootstrap.sh

Hello World can be now seen on http://localhost:8080.

For restful API you can use POST, PUT and GET methods on /rest/hello/ endpoint. For example using httpie:

$ http POST http://localhost:8080/rest/hello/ value=world
HTTP/1.0 200 OK
Content-Length: 16
Content-Type: application/json

Server: Werkzeug/0.14.1 Python/3.7.0

{
    "id": 1
}


$ http http://localhost:8080/rest/hello/1
HTTP/1.0 200 OK
Content-Length: 38
Content-Type: application/json
Date: Fri, 14 Sep 2018 14:09:24 GMT
Server: Werkzeug/0.14.1 Python/3.7.0

{
    "id": 1,
    "value": "world"
}
