Schedule cron jobs

​

Event Information

​

Meaning

• The Schedule Cron Jobs event in a Kubernetes cluster indicates that a CronJob resource has been successfully scheduled to run at a specified time or interval.
• It signifies that the Kubernetes scheduler has created a new Job based on the CronJob definition and scheduled it to run according to the specified cron schedule.
• This event is important for ensuring that periodic tasks or batch jobs are executed as per the defined schedule, which is crucial for maintaining the desired state of the cluster and performing regular maintenance tasks.

​

Remediation

1. Identify the CronJob that triggered the event:
   • Use the Kubernetes API to list all CronJobs in the cluster.
   • Filter the CronJobs based on the name or any other relevant criteria mentioned in the event.
   • Note down the name of the CronJob that needs to be remediated.
2. Delete the CronJob:
   • Use the Kubernetes API to delete the identified CronJob.
   • You can use the Python Kubernetes client library to interact with the API.
   • Use the delete_namespaced_cron_job method to delete the CronJob.
   • Provide the name of the CronJob and the namespace it belongs to as parameters to the method.
3. Recreate the CronJob with correct configuration:
   • Create a new Kubernetes manifest file in the correct format (YAML or JSON) with the corrected configuration for the CronJob.
   • Use the Kubernetes API to create the CronJob using the new manifest file.
   • You can use the create_namespaced_cron_job method from the Python Kubernetes client library.
   • Provide the new manifest file as a parameter to the method.
