Running Django management team on Elastic Beanstalk using cron

Question

I am running a small Django web application on Elastic Beanstalk. It uses django-background-tasks to run some asynchronous tasks. This works locally since I can run python manage.py process_tasksto complete tasks.

However, I had a bit more trouble getting this to work as desired after deploying to Elastic Beanstalk. I managed to get it working by including this "99_process_tasks.config" file in my .ebextensions folder (based on this in the AWS documentation)

files:
  "/etc/cron.d/process_tasks_cron":
    mode: "000644"
    owner: root
    group: root
    content: |
       * * * * * root /usr/local/bin/99_process_tasks.sh

  "/usr/local/bin/99_process_tasks.sh":
    mode: "000755"
    owner: root
    group: root
    content: |
          #!/bin/bash

      date > /tmp/date
      source /opt/python/run/venv/bin/activate
      cd /opt/python/current/app
      python manage.py process_tasks

commands:
  remove_old_cron:
    command: "rm -f /etc/cron.d/*.bak"

This worked because asynchronous tasks were being executed and their code was being executed, as expected.
