python-config

This repo demonstrates a lightweight python config suitable for multi-stage deployments in a serverless environment.

For context, please see my blog post.

Requirements

python version: 3.8

Development

1. Install pipenv: pip install pipenv
2. Build the environment: pipenv --python 3.8
3. Install dependencies (including dev dependencies): pipenv install --dev

Notes on pipenv

Make sure to set PIPENV_VENV_IN_PROJECT, e.g. in your ~/.zshrc or ~/.bash_profile via export PIPENV_VENV_IN_PROJECT=true. This allows VSCode to detect the correct virtualenv, as pipenv will put it into .venv in the workspace folder.

• If you need to enter a subshell where the the virtual env is activated, use: pipenv shell
• During development, use pipenv to manage dependencies:
  • pipenv install --dev some-package #install only for dev
  • pipenv install some-package #install for prod
• If something goes wrong in your pipenv, CTRL-d out of the venv subshell (if active), then nuke the venv via pipenv --rm and rebuild it (see above).
