Kuberenetes deployment Failing

My Kubernetes deployment is failing. Can anybody advise what could be going wrong.

My observation: When I remove the volume mount things the service bounce back

   volumeMounts:
            - name: my-volume
              mountPath: /app
      volumes:
       - name: my-volume
         hostPath:
          path: /tmp/vpath

Remove the above piece of the code

  State:          Waiting
  Reason:       CrashLoopBackOff
  Last State:     Terminated
  Reason:       ContainerCannotRun
  Message:      OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "./main": stat ./main: no such file or directory: unknown

Here is my deployment file

apiVersion: apps/v1

  annotations:
    kompose.cmd: kompose convert -f docker-compose.yml
    kompose.version: 1.22.0 (955b78124)

            - containerPort: 5001
            - containerPort: 5002
          volumeMounts:
            - name: my-volume
              mountPath: /app
      volumes:
       - name: my-volume
         hostPath:
          path: /tmp/vpath 
status: {}


apiVersion: v1
kind: Service
metadata:
  annotations:
    kompose.cmd: kompose convert -f docker-compose.yml
    kompose.version: 1.22.0 (955b78124)
  creationTimestamp: null

    - name: "5001"
      port: 5001
      targetPort: 5001
    - name: "5002"
      port: 5002
      targetPort: 5002
  selector:
    io.kompose.service: stservice
status:
  loadBalancer: {}

Can anyone advice why having volume mount causes this failure

I think you might be mounting the volume over the Dockerfile WORKDIR, so you are overwriting the file that it is looking for and throwing this error: "... /main: no such file or directory:".

If that is the issue update the docker WORKDIR or the mount path. If that is not the issue please include the Dockerfile.
