CronJobs

Use a Kubernetes CronJob to repeat a task on a schedule, such as refreshing data every night, running evaluations, or cleaning up old files. Each run creates a job whose status and logs you can inspect.

Create a cronjob

1. Open Kubernetes / CronJobs.
2. Select a namespace and open the create form.
3. Enter a name, select a plan, and choose a container image.
4. Enter the schedule using Kubernetes cron syntax.
5. Optionally enter a shell command, then create the cronjob.

Use kubectl for settings the form does not include. These let you control overlapping runs, retained job history, pauses, and late starts, or add labels, annotations, environment variables, storage, and other job settings.

Operating cronjobs on RemoteGPU

• Use concurrencyPolicy to choose whether runs of this cronjob can overlap. With Forbid, Kubernetes skips a scheduled start if the previous job is still running. A missed run may start later, depending on its deadline. See Kubernetes concurrency policy.
• Set the success and failure history limits to choose how many finished jobs to keep for inspection.
• Open Kubernetes / CronJobs to check each run's status, pods, events, and logs.

Troubleshooting

Symptom	What to check
CronJob does not create jobs	Confirm the schedule is valid Kubernetes cron syntax and the cronjob is not suspended
Scheduled jobs fail	Inspect the created job, pod events, and container logs; the job template follows the same rules as a normal Job
Runs overlap unexpectedly	Set concurrencyPolicy to Forbid to prevent runs of the same cronjob from overlapping
Completed jobs accumulate	Set successfulJobsHistoryLimit and failedJobsHistoryLimit in the cronjob manifest
Console-created cronjob needs advanced fields	Use kubectl for fields that are not exposed in the console form
