-------------------------------------
Summary: Set default kubernetes affinity and toleration settings
in airflow.cfg
Key: AIRFLOW-3402
URL: https://issues.apache.org/jira/browse/AIRFLOW-3402
Project: Apache Airflow
Issue Type: Improvement
Components: kubernetes
Reporter: Kevin Pullin
Currently airflow supports setting kubernetes `affinity` and `toleration`
configuration inside dags using either a `KubernetesExecutorConfig` definition
or using the `KubernetesPodOperator`.
In order to reduce having to set and maintain this configuration in every dag,
it'd be useful to have the ability to set these globally in the airflow.cfg
file. One use case is to force all kubernetes pods to run on a particular set
of dedicated airflow nodes, which requires both affinity rules and tolerations.
