I am newbie to airflow, We have a DAG with 3 tasks. Currently we are using Celery Executor as we need the flexibility to run an individual task. We don't want to schedule the workflow, for now it will be manual trigger. Is there any way to execute the entire workflow using the Airflow UI (Same as we have in oozie)?
Executing one task at a time is a pain.

In the Airflow web interface, on the DAGs page, in the Links column for your DAG, click the Trigger Dag button. (Optional) Specify the DAG run configuration. Click Trigger.
When you reload the Airflow UI in your browser, you should see your hello_world DAG listed in Airflow UI. In order to start a DAG Run, first turn the workflow on (arrow 1), then click the Trigger Dag button (arrow 2) and finally, click on the Graph View (arrow 3) to see the progress of the run.
Backfilling can be accomplished in Airflow using the CLI. You simply specify the DAG ID, as well as the start date and end date for the backfill period. This command runs the DAG for all intervals between the start date and end date. DAGs in your backfill interval are still rerun even if they already have DAG runs.
Overview. A notable feature of Apache Airflow is the UI, which provides insights into your DAGs and DAG Runs. The UI is a useful tool for understanding, monitoring, and troubleshooting your pipelines.
In Airflow 1.8 and higher there is a button for each dag on the dashboard that looks like a play button:
In older versions of Airflow, you can use the dialog found at:
Browse -> Dag Runs -> Create
Either one should kick off a dag from the UI.
