 The KubernetesExecutor runs as a process in the Scheduler that only requires access to the Kubernetes API (it does *not* need to run inside of a Kubernetes cluster). The KubernetesExecutor requires a non-sqlite database in the backend, but there are no external brokers or persistent workers needed.
