no such file or directory error while executing yaml file as a cron job

Question

I was trying to execute a yaml file as cron job and got the following error:

container_linux.go:247: starting container process caused "exec: \"/home/ubuntu/exam.sh\": stat /home/ubuntu/exam.sh: no such file or directory"

This is my yaml file:

job2.yaml file 
apiVersion: batch/v1beta1
 kind: CronJob metadata:
   name: ghost
   labels:
    role: blog
 spec:   schedule: "*/1 * * * *"   jobTemplate:
    spec:
      template:
        spec:
          containers:
          - name: ghost
            image: ghost:0.11-alpine
            command: ["/home/ubuntu/exam.sh"]
          restartPolicy: OnFailure

Answer 1

When you get errors like these, you first check if the job was executed a cron job, if the file exists and is executable

you can run it from kubectl run command:

kubectl run ghost --schedule="*/1 * * * *" --restart=OnFailure --image=ghost:0.11-alpine -- /bin/sh -c "your check script content"
