I have a cronjob which run once every midnight, however one day I deployed wrong version of it and consequently the pod it made went failed soon.
So.. the problem is when I delete the failed pod the cronjob immediately recreates it. How can I stop it? Well anyhow its image is already broken so however it recreates new pod again and again it'd go fail.
my question is "How can I delete failed pod created by cronjob?"
P.S. I'm using rancher but I'm not sure my problem is related to it.

You can use ttlSecondsAfterFinished to control how long you want to keep either Complete or Failed job in your cluster.
apiVersion: batch/v1
kind: CronJob
metadata:
...
spec:
schedule: ...
...
jobTemplate:
spec:
ttlSecondsAfterFinished: 43200 <-- example 12 hrs. 0 to clean immediately.
template:
...Another thing to note this is a K8s v1.21 beta feature at the point of this writing.
