Airflow service management via ADCM

Elena Kostyuchenko

The ADCM UI provides actions to manage the Airflow service and its components. The actions available for the Airflow service are listed in the table below.

For more information about Airflow components, see Airflow.

Action Description

Add/Remove components

Running this action opens the component-host mapping interface where you can add, remove, and distribute Airflow components

Check

Runs service-specific tests to check the health of the service and its components

Start

Starts the service. When you run this action, the option Apply configs from ADCM is available. If it is set to true, all service configurations defined in ADCM settings will be applied on the service startup. Otherwise, the service starts without applying configurations from ADCM

Stop

Stops the service

Restart

Restarts the service. When you run this action, the option Apply configs from ADCM is available. If it is set to true, all service configurations defined in ADCM settings will be applied during the service restart. Otherwise, the service restarts without applying configurations from ADCM

Remove

Removes the service from the cluster. This action should be used to remove already installed services. Whereas the delete control can be used to remove a non-mapped service (a service which components have not been distributed among cluster hosts)

Rotate fernet key

Rotates the Fernet encryption key. If Autogenerate new fernet key is set to True, ADCM will generate a new Fernet key automatically. The result depends on the Manage sensitive configuration data parameter, see Fernet key rotation. This action will require several restarts of the Airflow service

Sync permission

Updates permissions for existing roles

Sync requirements

Updates Airflow dependencies on all hosts. Restart is required to apply the changes

Some of the above actions are also available for Airflow on a per-component basis. Available component actions are listed in the table below.
