I am trying to create a cronjob , I have written a Springboot application for this and have created a abc-dev.yml file for application configuration
error: unable to recognize "src/java/k8s/abc-dev.yml": no matches for kind "CronJob" in version "apps/v1"
apiVersion: apps/v1
kind: CronJob
metadata:
name: abc-cron-job
spec:
schedule: "* * * * *"

container:
- name: abc-cron-job
image: busybox
imagePullPolicy: IfNotPresent
command:
- /bin/sh
- -c
- date; echo Hello from the Kubernetes cluster
restartPolicy: OnFailure You can check the api-version of a resource with the
kubectl api-resources
command. In this case:
kubectl api-resources | grep cronjob | awk -v N=3 '{print $N}'
The output is 'batch/v1'.
If you are running kubernetes 1.20 or lower, the correct apiVersion value is:
apiVersion: batch/v1beta1
If you are running kubernetes 1.21 or higher, its
apiVersion: batch/v1
Cronjob belongs to batch/v1 k8s api. You should check api version before creating resources in any case they sometimes change.
