a CronTab. This example use an example CRD from this tutorial:

https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/

The following yaml manifest has to be applied first:

apiVersion: apiextensions.k8s.io/v1

kind: CustomResourceDefinition

metadata:

name: crontabs.stable.example.com

spec:

group: stable.example.com

versions:

- name: v1

served: true

storage: true

scope: Namespaced

names:

plural: crontabs

singular: crontab

kind: CronTab

shortNames:

- ct
