kubernetes on minikube can't output to file
Your job should like like this:
apiVersion: batch/v1kind: Jobmetadata: name: pi13spec: template: spec: containers: - name: pi image: perl command: [ "sh", "-c"] args: ["echo 1 >> /data/text12.txt"] volumeMounts: - mountPath: /data name: data volumes: - name: data hostPath: path: /tmp/data restartPolicy: Never backoffLimit: 1In your case you pass whole 1 >> /data/text12.txt to echo command and as results it prints 1 >> /data/text12.txt what you can check in job logs.
hostPath creates directory /data, so this is why you found it.
I hope it helps.
