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 theAIRFLOW__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[database]
sectionfernet_key
in[core]
sectionbroker_url
in[celery]
sectionflower_basic_auth
in[celery]
sectionresult_backend
in[celery]
sectionpassword
in[atlas]
sectionsmtp_password
in[smtp]
sectionsecret_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 keyAIRFLOW_CONN_PROXY_POSTGRES_TCP
with the connection URI as the value.For more information, see: Security of connections in the database.
- 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.
