Minimalist scheduling. A mobile friendly, fast, self-hosted Doodle alternative.
The Diddle app is a traditional Flask web app that uses PostgreSQL for persistence. User settings are stored in HTTP cookies.
Build a container image with docker compose (see compose.yml):
docker compose build
or directly with docker build:
docker build -t diddle:latest .
Deploy the image as you see fit.
You can also run the app without containerization:
pip install -r requirements.txt # install pip dependencies
touch .env # put your env vars here
python apply_migrations.py # prepare the database
gunicorn --bind "0.0.0.0:8000" -w 4 app:app
