A quickstart recipe for running a Python script on a cron job inside a docker container.

Usage

1. Replace src/script.py with your Python file.
2. Add any requirements for the Python script in /src/requirements.txt.
3. Replace src/crontab/ with your desired cron (see https://crontab.guru/).
4. In the root directory, run
   • docker build -t IMAGE_NAME .
   • docker run -d --name CONTAINER_NAME IMAGE_NAME (including any other arguments you might need e.g. environment variables)

Ensure src/script.py and src/crontab have Unix line endings. For further CRON debugging see this post
