Environment Variables¶

AIRFLOW__{SECTION}__{KEY}¶

Sets options in the Airflow configuration. This takes priority over the value in the airflow.cfg file.

Replace the {SECTION} placeholder with any section and the {KEY} placeholder with any key in that specified section.

For example, if you want to set the dags_folder options in [core] section, then you should set the AIRFLOW__CORE__DAGS_FOLDER environment variable.

For more information, see: Setting Configuration Options.

AIRFLOW__{SECTION}__{KEY}_CMD¶

For any specific key in a section in Airflow, execute the command the key is pointing to. The result of the command is used as a value of the AIRFLOW__{SECTION}__{KEY} environment variable.

This is only supported by the following config options:

sql_alchemy_conn in [core] section
fernet_key in [core] section
broker_url in [celery] section
flower_basic_auth in [celery] section
result_backend in [celery] section
password in [atlas] section
smtp_password in [smtp] section
secret_key in [webserver] section

AIRFLOW__{SECTION}__{KEY}_SECRET¶

For any specific key in a section in Airflow, retrieve the secret from the configured secrets backend. The returned value will be used as the value of the AIRFLOW__{SECTION}__{KEY} environment variable.

See Secrets Backends for more information on available secrets backends.

This form of environment variable configuration is only supported for the same subset of config options as AIRFLOW__{SECTION}__{KEY}_CMD

AIRFLOW_CONFIG¶: The path to the Airflow configuration file.

AIRFLOW_CONN_{CONN_ID}¶

Defines a new connection with the name {CONN_ID} using the URI value.

For example, if you want to create a connection named PROXY_POSTGRES_TCP, you can create a key AIRFLOW_CONN_PROXY_POSTGRES_TCP with the connection URI as the value.

For more information, see: Storing a Connection in Environment Variables.

AIRFLOW_HOME¶: The root directory for the Airflow content. This is the default parent directory for Airflow assets such as DAGs and logs.

AIRFLOW_VAR_{KEY}¶

Defines an Airflow variable. Replace the {KEY} placeholder with the variable name.

For more information, see: Managing Variables.
