Simple Python Docker cron

Simple Docker Ubuntu cron-tab setup with Python script.

Getting started

setup project

• Click 'Use this Template'
• checkout your new project: git clone git@github.com:<your-github-name>/<created-project-name>.git
• jump into folder and run: make init
  • creates the default .env file (only if it doesnt exists already)
  • creates a fresh python virtual environment

start coding

• put your (existing) python code into src/.
  • important: your main file should be named: main.py
• you can run your code with make or make python-run
• if you want to add new pypi dependencies:
  • put your pypi dependencies into requirements.txt
  • run make python-install to setup a new python virtual environment

build & run the container with docker

• in file python-cron configure cron schedule by replacing the * symbols (for help: crontab schedule builder)
• running make container will build the cron-tab-docker-container and starting it with docker-compose
• if you want to build and run independently use:
  • make container-build to build the container
  • make container-run to run the container
  • make container-run-detached to run the container in the background

envrionment variables

• you can add environment variables to env/.env
• all variables will be visible:
  • in docker-compose.yml
  • in your apps execution environment (local and contnainer)
