Apache Airflow includes a command-line interface (CLI) that you can use to manage Airflow environments. The CLI is useful for tasks such as managing workflows, changing the Airflow environment, and obtaining log information.
Cloud Composer simplifies Airflow CLI commands with the Google Cloud SDK.
Once installed, you can use the
gcloud command line tool to run
gcloud composer environments run command to execute
Airflow CLI sub-commands.
Before you begin
The following permissions are required to access the
gcloud command-line tool (Airflow CLI)
in the Cloud Composer environment:

Running Airflow CLI commands
You can run Airflow CLI commands on a Cloud Composer environment by using the following command:
gcloud composer environments run ENVIRONMENT_NAME \ --location LOCATION SUBCOMMAND
gcloud composer commands require a location. You can specify the location by
--location flag or by setting the default location.
For example, to trigger a DAG named
sample_quickstart with the ID
5077 in your Cloud Composer environment:
gcloud composer environments run test-environment \ --location us-central1 trigger_dag -- sample_quickstart \ --run_id=5077
For example, to check for syntax errors in DAGs in a
gcloud composer environments run test-environment \ --location us-central1 \ list_dags -- -sd /home/airflow/gcs/data/test
