Apache Airflow; AIRFLOW-6506; KubernetesPodOperator defaulting do_xcom_push to True after 1.10.7 release
Nov 04, 2019 · DAG example using KubernetesPodOperator, the idea is run a Docker container in Kubernetes from Airflow every 30 minutes. Features: Scheduled every 30 minutes. Set environment variable for the pod RULES. Run the pods in the namespace default. Mount a volume to the container. It's just an example mounting the /tmp from host.
The KubernetesPodOperator spins up a pod to run a Docker container in. If you are running Airflow on Kubernetes, it is preferable to do this rather than use the DockerOperator. This tutorial is for anyone using Airflow 1.9 and would like to use the KubernetesPodOperator without upgrading their version of Airflow.
Use of XCom¶ We can enable the usage of XCom on the operator. This works by launching a sidecar container with the pod specified. The sidecar is automatically mounted when the XCom usage is specified and it’s mount point is the path /airflow/xcom. To provide values to the XCom, ensure your Pod writes it into a file called return.json in the ...
Feb 12, 2019 · That is a lot of output. The first thing I would look at in this output are the Events.This will tell you what Kubernetes is doing. Reading the Events section from top to bottom tells me: the pod was assigned to a node, starts pulling the images, starting the images, and then it goes into this BackOff state.
9 hours ago · Trying to access the dag_run.conf['myValue'] via the KubernetesPodOperator in airflow 1.10.9 (GCP Composer). I'm able to access it in a pythonOperator and write to xcom. In addition we can read from XCom in the podOperator but the dag_run configs are not working, any help would appreciated!

Jul 11, 2019 · The KubernetesPodOperator handles communicating XCom values differently than other operators. The basics are described in the operator documentation under the xcom_push parameter. I’ve written up a more detailed example that expands on that documentation.
I want to test a dag in airflow end to end. I have some fixed input data and some expected results. I tried googling around, unfortunately i can only find information related to unit tests.

Sep 27, 2020 · It's function has been unified under a common name (do_xcom_push) on BaseOperator. This way it is also easy to globally disable pushing results to xcom. The following operators were affected: DatastoreExportOperator (Backwards compatible) DatastoreImportOperator (Backwards compatible) KubernetesPodOperator (Not backwards compatible)
KubernetesPodOperator will run what inside image. I think you have two choices. 1. implement load_users_into_table and build docker image then you run it with KubernetesPodOperator 2. run the code with PythonOperator – humbledude 15 hours ago

Jan 25, 2019 · Gracefully Stopping Containers in Kubernetes. This is part 2 of our journey to implementing a zero downtime update of our Kubernetes cluster. In part 1 of the series, we laid out the problem and the challenges of naively draining our nodes in the cluster.
XCom 是 Cross-communication 的縮寫,在 Airflow 每個工作都是獨立的實體,所產生的任何資料會隨著工作完成消失,如果想取得其他工作的資料可以透過 XCom 傳遞,但需注意 XCom 的大小是有限制的,僅適合用來傳遞 ID、檔名等可辨識的唯一值,交給其他 Operator 把完整 ...
Tasks can pass data between each other using XComs. When an XCom is returned from a task, it gets stored in the Airflow database. The prometheus exporter reads the Airflow database and so is able to use XCom values as metrics. To make the KubernetesPodOperator return an XCom, first the task must have XCom passing enabled like this one. The Airflow version we are on is between versions of how to enable XComs, which is why this one may have two different booleans to enable XCom passing.

The corecommendations DAG file dynamically creates three DAGs, one for each model. DAG separation. One of our models has a few different DAGs. If some task doesn’t depend on the schedule or upstream tasks in a current DAG, it may be better to separate the DAGs, especially if the DAG needs to run often, and the task(s) slow the DAG down.
