# For example if you wanted to set an environment variable with value `prod` and key

# ``<environment_variable_mount> = <kubernetes_secret_object>=<kubernetes_secret_key>``
#
# For example if you wanted to mount a kubernetes secret key named ``postgres_password`` from the
# kubernetes secret object ``airflow-secret`` as the environment variable ``POSTGRES_PASSWORD`` into
# your workers you would follow the following format:
# ``POSTGRES_PASSWORD = airflow-secret=postgres_credentials``
