If you are deploying an image with a constant tag, you need to make sure that the image is pulled every time.

.. warning::

Using constant tag should be used only for testing/development purpose. It is a bad practice to use the same tag as you'll lose the history of your code.

.. code-block:: bash

helm upgrade --install airflow apache-airflow/airflow \
--set images.airflow.repository=my-company/airflow \
--set images.airflow.tag=8a0da78 \
--set images.airflow.pullPolicy=Always
--set images.airflow.pullPolicy=Always \
--set airflowPodAnnotations.random=r$(uuidgen)
