Debugging with Airflow CLI - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to list all DAGs using the Airflow CLI.

Apache Airflow

airflow [1] list

Drag options to blanks, or click blank then click option'

Adags

Btrigger

Ctasks

Dvariables

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'trigger' instead of 'dags' causes an error because 'trigger' is for triggering DAG runs.

Using 'tasks' or 'variables' lists tasks or variables, not DAGs.

The command airflow dags list lists all DAGs available in Airflow.

2fill in blank

medium

Complete the command to trigger a DAG run named 'example_dag'.

Apache Airflow

airflow dags [1] example_dag

Drag options to blanks, or click blank then click option'

Alist

Bpause

Ctrigger

Dunpause

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'list' only shows DAGs, does not start a run.

Using 'pause' or 'unpause' changes DAG state but does not trigger runs.

The trigger command starts a DAG run immediately.

3fill in blank

hard

Fix the error in the command to view logs of a task instance for DAG 'example_dag', task 'task1', run on '2023-01-01'.

Apache Airflow

airflow tasks [1] example_dag task1 2023-01-01

Drag options to blanks, or click blank then click option'

Alogs

Bview_log

Cshow_logs

Dlog

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'log' causes a command not found error.

Using 'show_logs' or 'view_log' are invalid subcommands.

The correct subcommand to view logs is logs (plural).

4fill in blank

hard

Fill both blanks to list all tasks of DAG 'example_dag' for run date '2023-01-01'.

Apache Airflow

airflow tasks [1] example_dag --[2] 2023-01-01

Drag options to blanks, or click blank then click option'

Alist

Brun

Cexecution_date

Dstart_date

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'run' instead of 'list' lists a task run, not tasks.

Using '--start_date' is invalid for this command.

The list command shows tasks, and --execution_date specifies the run date.

5fill in blank

hard

Fill all three blanks to clear task instances for DAG 'example_dag', task 'task1', on date '2023-01-01' with confirmation skipped.

Apache Airflow

airflow tasks [1] example_dag task1 --[2] 2023-01-01 --[3]

Drag options to blanks, or click blank then click option'

Aclear

Bexecution_date

Cyes

Dforce

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'run' instead of 'clear' does not clear tasks.

Using '--force' is not a valid flag to skip confirmation.

Omitting '--yes' causes the command to ask for confirmation.

The clear command clears task instances, --execution_date specifies the date, and --yes skips confirmation.
