ephraimbuddy opened a new pull request, #68848:
URL: https://github.com/apache/airflow/pull/68848
The kubernetes client (v36) attaches the process-global in-cluster
Configuration to every model it deserializes, and that Configuration's
refresh_api_key_hook is an unpicklable local closure. Any deserialized model
that later gets pickled -- for example a pod_override placed on the
KubernetesExecutor multiprocessing queue -- then crashes.
Deserialize through an ApiClient built with a fresh Configuration in the
provider's model-deserialization paths so the resulting models (and every
nested object) stay picklable regardless of the kubernetes client version:
PodGenerator.deserialize_model_dict,
KubernetesJobOperator.deserialize_job_template_file, and the backcompat
_convert_from_dict converter.
