Can I configure my kubernetes job to run for a specified time

Question

I have a kubernetes job that should run for 40 seconds ideally but sometimes its taking almost 5 minutes to execute.How can i ensure that the application stops if it exceeds 40 seconds? Please help.

When we create a job spec, we can give --activeDeadlineSeconds  flag to the command. 

This flag relates to the duration of the job, once the job reaches the threshold specified by the flag, the job will be terminated.

kind: CronJob
apiVersion: batch/v1beta1
metadata:
  name: mycronjob
spec:
  schedule: "*/1 * * * *"
activeDeadlineSeconds: 200
  jobTemplate:
    metadata:
      name: google-check-job
    spec:
      template:
        metadata:
          name: mypod
        spec:
          restartPolicy: OnFailure
          containers:
            - name: mycontainer
             image: alpine
             command: ["/bin/sh"]
             args: ["-c", "ping -w 1 google.com"]
