Passing parameters on manual trigger

Question

How do you pass parameters during a manual DAG trigger?

Solution

Trigger with configuration JSON:

{ "customer_id": 123, "environment": "prod" }

Access via DAG run conf, often with Jinja:

{{ dag_run.conf["customer_id"] }}

Watch missing keys: optional values can blow up if you access them unsafely.
