--------------------------------------------
Summary: 405 when using REST api to get status of a DAG
Key: AIRFLOW-4043
URL: https://issues.apache.org/jira/browse/AIRFLOW-4043
Project: Apache Airflow
Issue Type: Bug
Components: api
Affects Versions: 1.10.2
Environment: I'm running airflow in kubernetes on ubuntu 16.04
Reporter: Paymahn Moghadasian
I'm trying to use the airflow REST api (v1.10.2) but I'm having problems any
time I try to query information about a specific dag.
Here's an example of the latest_runs endpoint working:
{noformat}
❯❯❯ curl -X GET http://192.168.99.100:30080/api/experimental/latest_runs
{
"items": [
{
"dag_id": "test_dag",
"dag_run_url":
"/admin/airflow/graph?dag_id=test_dag&execution_date=2019-03-07+21%3A18%3A23.387031%2B00%3A00",
"execution_date": "2019-03-07T21:18:23.387031+00:00",
"start_date": "2019-03-07T21:18:23.683240+00:00"
}
]
}
{noformat}
However, when I try to query test_dag I get an error:
{noformat}
❯❯❯ curl -X GET
"http://192.168.99.100:30080/api/experimental/dags/test_dag/dag_runs";
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>405 Method Not Allowed</title>
<h1>Method Not Allowed</h1>
<p>The method is not allowed for the requested URL.</p>
{noformat}
I've also tried looking in the source code and I found that there's a [state
param|https://github.com/apache/airflow/blob/f4277cb32a3b75591ed6decb9f8d6c33f60986be/airflow/www/api/experimental/endpoints.py#L117]
that can be used:
{noformat}
❯❯❯ curl -X GET
"http://192.168.99.100:30080/api/experimental/dags/test_dag/dag_runs?state=success";
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>405 Method Not Allowed</title>
<h1>Method Not Allowed</h1>
<p>The method is not allowed for the requested URL.</p>
{noformat}
but adding that in doesn't seem to help.
I find that triggering a DAG works:
{noformat}
❮❮❮ curl -X POST \
http://192.168.99.100:30080/api/experimental/dags/test_dag/dag_runs \
-H 'Content-Type: application/json' \
-d '{}'
{
"message": "Created <DagRun test_dag @ 2019-03-07 22:31:18+00:00:
manual__2019-03-07T22:31:18+00:00, externally triggered: True>"
}
{noformat}
Anyone have an idea why I can't query the status of a DAG and get a 405?
