when I’m trying to pull a docker image, it throws this error ImagePullBackOff

NAME                                   READY   STATUS             RESTARTS   AGE

My docker image is @ https://hub.docker.com/repository/docker/narasingu/node-docker

My deployment yaml configuration is

---

apiVersion: v1
metadata:
    name: nodejs-server-service
spec:
    selector:
        app: nodejs-server-app

        targetPort: 80
        nodePort: 32000

Looks like it's not pulling the docker image, any help?
