While working through an example of doing XComs with the KubernetesPodOperator, the
env_varsattribute is used to pass templated values into the kubernetes pod. The@task.decoratoruses the_KubernetesDecoratedOperatorclass in this file. It overrides thetemplate_fieldsand excludesenv_varsfrom being rendered.Given that
env_varsseems to be the standard approach passing XComs into a kubernetes pod, I think this should be enabled. Its a quite a simple change.This line https://github.com/fletchjeff/airflow/blob/main/airflow/providers/cncf/kubernetes/decorators/kubernetes.py#L60
goes from:
template_fields: Sequence[str] = ("op_args", "op_kwargs",)to:
template_fields: Sequence[str] = ("op_args", "op_kwargs", "env_vars")No other changes are made.
