Uses a Custom Resource Definition (CRD) to create a custom object, in this case
|
|
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
