Kubernetes reports ImagePullBackOff for pod on minikube - kubernetes

Question

I've built a docker image within the minikube VM. However I don't understand why Kubernetes is not finding it?
minikube ssh
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
diyapploopback latest 9590c4dc2ed1 2 hours ago 842MB
And if I describe the pod:
kubectl describe pods abcxyz12-6b4d85894-fhb2p

Seems I'm able to run it directly (only for debugging/diagnoses purposes..):
kubectl run abcxyz123 --image=diyapploopback --image-pull-policy=Never
If I describe the above deployment/container I get:

Answer 1

imagePullPolicy: IfNotPresent
The above was not present (and it is required...) in my image config within the deployment...
