Schedule a Kubernetes Job in AWS and GCP by creating a CronJob in the DuploCloud Portal
A Kubernetes CronJob is a variant of a Kubernetes Job, with the exception that you can schedule a CronJob to run at periodic intervals.
See the Kubernetes documentation on CronJobs for more information.
In the DuploCloud Portal, navigate to Kubernetes -> CronJob.
Click Add. The Add Kubernetes CronJob page displays.
In the Basic Options step, specify the Kubernetes CronJob Name.
In the Schedule field, specify the Cron Schedule in Cron Format. Click the Info Tip icon for examples. When specifying a Schedule in Cron Format, ensure you separate each value with a space. For example, 0 0 * * 0
is a valid Cron Format input; 00**0
is not. See the Kubernetes documentation for detailed information about Cron Format.
In the Container - 1 area, specify the Container Name and associated Docker Image.
In the Command field, specify the command attributes for Container - 1. Click the Info Tip icon for examples. Select and Copy commands as needed.
In the Init Container - 1 area, specify the Container Name and associated Docker Image.
Click Next to open the Advanced Configuration step.
Click Create. The K8s CronJob is created and displayed on the CronJob page and will be run according to the schedule you specified.
In the DuploCloud Portal, navigate to Kubernetes -> CronJob.
Select the CronJob you want to view and click the Overview, Schedule, and Details tabs for more information about the job schedule and job history.
You can also view CronJobs linked to containers by clicking the container Name on the Containers page (Kubernetes -> Containers).
You can filter container names by using the search field at the top of the page, as in this example:
In the DuploCloud Portal, navigate to Kubernetes -> CronJob.
Select the K8s CronJob you want to edit.
