View Public Instance Variables

For Airflow version 1.10.0 and older:

GET /airflow-webserver-<cluster-id>/api/experimental/dags/<DAG_ID>/dag_runs/<string:execution_date>/tasks/<TASK_ID>

For Airflow 1.10.2 and later:

GET /airflow-rbacwebserver-<cluster-id>/api/experimental/dags/<DAG_ID>/dag_runs/<string:execution_date>/tasks/<TASK_ID>

You can now use this API to return a JSON with a task instance’s public instance variables. Use this format YYYY-mm-DDTHH:MM:SS (Example: “2016-11-16T11:34:15”) to specify the value of <string:execution_date>.


To run the experimental APIs, you require to have Airflow version 1.10.0 and above.
