To illustrate, lets create a yaml file to override values under these sections of the +``values.yaml`` file. + +.. code-block:: yaml + + secret: + - envName: "my-env" + secretName: "my-secret-name" + secretKey: "my-secret-key" + + + extraSecrets: + {{ .Release.Name }}-airflow-connections: + data: | + AIRFLOW_CONN_GCP: 'base64_encoded_gcp_conn_string' + AIRFLOW_CONN_AWS: 'base64_encoded_aws_conn_string' + stringData: | + AIRFLOW_CONN_OTHER: 'other_conn' + {{ .Release.Name }}-other-secret-name-suffix: | + data: | + + +Variables +--------- +Airflow supports Variables which enable users craft dynamic DAGs. You can set variables in Airflow in three ways - UI, +commandline, and within your DAG file. See:doc:`/howto/variable`.` for more. + +With Helm chart, you can also inject environment variables into airflow. For example, in a yaml file to +override values of interest in the ``env`` section of the ``values.yaml`` file. + +.. code-block:: yaml + + env: + - name: "AIRFLOW_VAR_KEY" + value: "value_1" + + - name: "AIRFLOW_VAR_ANOTHER_KEY" + value: "value_2" + + +You can also utilize the ``extraEnv`` and ``extraEnvFrom`` to set more possibly "templatable" values for your airflow +deployment.
