+Actions executed at image start
+-------------------------------
+
+If you are using the default entrypoint of the production image,
+there are a few actions that are automatically performed when the container starts.
+In some cases, you can pass environment variables to the image to trigger some of that behaviour.
+
+The variables that control the "execution" behaviour start with ``_AIRFLOW`` to distinguish them
+from the variables used to build the image starting with ``AIRFLOW``.
+
+Creating system user
+....................
+
+Airflow image is Open-Shift compatible, which means that you can start it with random user ID and group id 0.
+Airflow will automatically create such a user and make it's home directory point to /home/airflow.
