Has anyone here tried something like this (and hopefully had success with it)?Īlternatively, has anyone had success with the CLI approach? Informational requests for status work fine but trying to clear a DAGRun or TaskInstance fails, yielding generally unhelpful errors which mask underlying causation considerably. I want to call a REST end point using DAG. We have a dedicated automation test user with its own key/secret pair which we've used for logging into the UI to have Selenium drive the Airflow UI (something we're trying to get away from). How to call a REST end point using Airflow DAG Ask Question Asked 3 years, 11 months ago Modified 1 year, 6 months ago Viewed 18k times 7 I'm new to Apache Airflow. I haven't found: 1) which token to generate (CLI token, web login token, other?), 2) how to compose the headers for the request, 3) whether this is generally disabled outside of the use of the provided UI wrapper. A situation like this happened to us and. Our first assumptions were that we'd need to create a token (using boto3 to create an mwaa-client, then getting a token for that client) to pass in a header for the requests we'd like to make. Direct access to the native Airflow API is unsupported because bypassing the CDE API prevents job tracking, centralized monitoring, and metadata tracking. Access Airflow REST API using a service account Go to the Airflow UI. If youre working with Airflow chances are that some of your DAGs may require access to data obtained through an API. Go to Security > List Users and click Add a new record. The hurdle currently is how to access this API generally. Access Airflow REST API using a service account Go to the Airflow UI. Through the UI, I have identified the specific requests I want to make and I've confirmed that they do what I want there. I would really like to be able perform these requests outside of this UI in our test automation framework somehow. In our MWAA instances, I can navigate to the presentation of the Airflow REST API from the Airflow dashboard (Docs > REST API Reference (Swagger UI)) and perform various API operations (getting DAG/task status, clearing DAGs/tasks to re-run, etc.). For Airflow 1.10.2 and later: GET /airflow-rbacwebserver- I'm having considerable difficulty in finding definitive documentation about this and I'm hoping that someone has already figured this out. GET /airflow-webserver-/api/experimental/dags//paused/. Thus, it can be more memory and CPU intensive compared to a non-paginated call. All API responses are stored in memory by the Operator and returned in one single result. Remember to unblock IP traffic to Airflow REST API using Webserver Access Control. The HttpOperator also allows to repeatedly call an API endpoint, typically to loop over its pages.

Tell us here Depending on the method used to call Airflow REST API, the caller method can be using either IPv4 or IPv6 address.

Apache Airflow for Data Science 7 - How to Work with REST APIs. Note: ensure to redact or obfuscate all confidential or identifying information (eg. The full Airflow DAG itself I won't post, but in the excerpt below I show how to use the filename in the DAG.News, articles and tools covering Amazon Web Services (AWS), including S3, EC2, SQS, RDS, DynamoDB, IAM, CloudFormation, AWS-CDK, Route 53, CloudFront, Lambda, VPC, Cloudwatch, Glacier and more. The nice thing here is that I'm actually passing the filename of the new file to Airflow, which I can use in the DAG lateron. You wont see it straight away on the Airflow homepage, so youll have to restart both the webserver. You need to adjust the AIRFLOW_URL, DAG_NAME, AIRFLOW_USER, and AIRFLOW_PASSWORD.
