## livenessProbe

    livenessProbe:
      exec:
        command:
        - cat
        - /tmp/healthy
      initialDelaySeconds: 5
      periodSeconds: 5

this is a check to restart the container on the same pod if the command ls /var/www/html/file_check fails. This check should start after a delay of 10 seconds and run every 60 seconds.
