Local Development Environment Verification

If you want to verify your changes locally before deploying to the target environment, you can use the Composer Local Development CLI tool (composer-dev).

1. List and Describe Local Environments

1. List Local Environments: composer-dev list
2. Describe Local Environment: composer-dev describe <LOCAL_ENV_NAME>

2. Identify Active Environment and DAGs Location

• Active Environment: Specified by <LOCAL_ENV_NAME>.
• DAGs Location: Shown in composer-dev describe output under Dags directory. Copy your migrated DAGs to this directory to test.

3. Verify DAGs and Check for Import Errors

1. List Parsed DAGs:

   composer-dev run-airflow-cmd <LOCAL_ENV_NAME> dags list
   

2. Check for Import Errors:

   composer-dev run-airflow-cmd <LOCAL_ENV_NAME> dags list-import-errors
