Failed to extract xcom from airflow pod - Kubernetes Pod Operator

Question

While running a DAG which runs a jar using a docker image,
xcom_push=True is given which creates another container along with the docker image in a sing

Answer 1

If xcom_push is True then KubernetesPodOperator creates one more sidecar container (airflow-xcom-sidecar) in Pod along with the base container(actual worker container). This sidecar container reads data from /airflow/xcom/return.json and returns as xcom value. So in your base container you need to write the data you want to return in /airflow/xcom/return.json file.
