django_docker_helpers.db.ensure_caches_alive(max_retries=100, retry_timeout=5, exit_on_failure=True)

Checks every cache backend alias in settings.CACHES until it becomes available. After max_retries attempts to reach any backend are failed it returns False. If exit_on_failure is set it shuts down with exit(1).

It sets the django-docker-helpers:available-check key for every cache backend to ensure it’s receiving connections. If check is passed the key is deleted.
