+# The script triggers a CronTask inside of Drupal, following these steps:
+#   1. Retrieve the cron_key of the website
+#   2. Make a http request to the website using the key in order to trigger a CronTask
+# Issue link: https://gitlab.cern.ch/webservices/webframeworks-planning/-/issues/437
+# Note: If in the future we want to have more periodic actions made to the Drupalsites
+# or want to trigger CronTasks in a different way, all we need is to edit this script.
+# The DrupalSite operator is only involved to create a CronJob that executes this script.
