apiVersion: batch/v1
kind: CronJob
metadata:
  name: xfusion

      template:
        spec:
          containers:
          - name: cron-xfusion
            image: nginx:latest
            command:

• For CronJob , apiversion is batch/v1 and kind is CronJob. CronJob name is set in metadata section.
• Mentioned earlier, schedule was defined in .spec.schedule field.
• To define the job for cronjob, we have to use .spec.jobTemplate field.
• To define what the container to do when cronjob is scheduled. we can use can built-in image for to do that task or we can define commands to run in the container by using command in the container section.

After defining the manifest file. We created a cronjob using kubectl command and list the cronjobs created.

We can also get detailed info about cronjob by using the command

kubectl describe cronjob xfusion
