If need to run Kubernetes CronJob manually from test purposes or etc, use:
kubectl create job --from=cronjob/cron_job_name job_name
- cron_job_name – Kubernetes CronJob that was created
- job_name – any unique name. It will be used for pod name
kubectl create job --from=cronjob/backup backup-manual-1
Be careful in the situation when your job uses persistent storage because in this case one job can be executed at one time.
