Dockerizing flask, postgres, nginx

Teaching myself how to work with the python ecosystem by working with Python Flask Framework.

Demo

Prerequisite

1. Make sure you have the following installed on your machine:

   • git
   • python3
   • pip3
   • docker
   • docker-compose

2. If you are using WSL and ubuntu in your workflow, you can set up everything following this repo: https://github.com/Klezca/dev-workflow-setup

To run this project in docker

docker-compose up -d --build

To run this project in venv

# Build venv
python3.8 -m venv env

# Run venv
source env/bin/activate

Run linter

# For docker workflow

# Perform a dry-run of black to check what files will be formatted
docker-compose exec web black project --check

# Run black to format the python code
docker-compose exec web black project

# Run isort to sort import library
docker-compose exec -T web /bin/sh -c "isort project/*/*.py --check-only"

# Run flake8 to check if python styling is enforced
docker-compose exec web flake8 --ignore=E501,F401 project

# For venv workflow

# Run black to format the python code
black services/web/project

# Run isort to sort import library
isort services/*/*/*.py

# Run flake8 to check if python styling is enforced
flake8 --ignore=E501,F401 services/web/project

Run the tests with coverage (without outputting warnings)

docker-compose exec web python -m pytest "project/tests" -p no:warnings --cov="project"
