BobSong-dev opened a new pull request, #71763:
URL: https://github.com/apache/airflow/pull/71763
Summary
Add the `airflowctl tasks logs` command to fetch a task instance's logs for
a given try through the existing REST endpoint.
Changes
- Add `TaskInstancesOperations.logs()` calling `GET
/api/v2/dags/{dag_id}/dagRuns/{dag_run_id}/taskInstances/{task_id}/logs/{try_number}`.
- Register the `tasks logs` command: `airflowctl tasks logs DAG_ID
DAG_RUN_ID TASK_ID [--map-index N] --try-number N`; `--try-number` is required
(the endpoint has no server-side latest-attempt fallback).
- Keep required parameters positional per the airflowctl parameter style
consensus (#66768); the issue's suggested `--dag-id`/`--dag-run-id`/`--task-id`
flag form was dropped to comply with that convention.
- Limit scope to the primary logs endpoint; `externalLogUrl` handling is
left for a follow-up.
Testing
Added unit tests covering the command: explicit try number and map index,
required --try-number validation, structured and plain-text log output, 404
handling, and non-404 error propagation. All 36 tests in `test_task_command.py`
pass. Added `tasks logs` lines to the integration test command list. `ruff
format` and `ruff check` pass on all changed files.
closes: #69947
