Fix Kubernetes Cron Job invalid: spec.template field is immutable

The Kubernetes job on apply fails.

kubectl apply -f /home/my.job.yaml

Error

The Job "xyz" is invalid: spec.template: Invalid value: core.PodTemplateSpec{ObjectMeta:v1.ObjectMeta{:} field is immutable

Solution

The job once applied, can’t be re-applied.

We should delete the job as follows and apply again.

kubectl delete -f /home/my.job.yaml
