title: For Apache Airflow, How can I pass the parameters when manually trigger DAG via CLI?
body: <p>I use Airflow to manage ETL tasks execution and schedule. A DAG has been created and it works fine. But is it possible to pass parameters when manually trigger the dag via cli.</p>
  
  <p>For example:
  My DAG runs every day at 01:30, and processes data for yesterday(time range from 01:30 yesterday to 01:30 today). There might be some issues with the data source. I need to re-process those data (manually specify the time range).</p>
  
  <p>So can I create such an airflow DAG, when it's scheduled, that the default time range is from 01:30 yesterday to 01:30 today. Then if anything wrong with the data source, I need to manually trigger the DAG and manually pass the time range as parameters.</p>
  
  <p>As I know <code>airflow test</code> has <code>-tp</code> that can pass params to the task. But this is only for testing a specific task. and <code>airflow trigger_dag</code> doesn't have <code>-tp</code> option. So is there any way to tigger_dag and pass parameters to the DAG, and then the Operator can read these parameters?</p>
  
  <p>Thanks!</p>
