Serving service from kfserving github examples created with kubectl, but can not infere
I have installed minikube cluster and kfserving on a linux desktop.
Then I have followed two tutorials 
https://github.com/kubeflow/kfserving/tree/master/docs/samples/v1beta1/custom/torchserve 
https://github.com/kubeflow/kfserving/tree/master/docs/samples/v1alpha2/custom/kfserving-custom-model 
In the second tutorial I have needed to move &quot;name: custom&quot; from &quot;custom:&quot; section to &quot;container:&quot; section in the yaml file. 
I expected that serving service was working and responding to serving requests and pods of the service where in kubernetes.  
I use the newest stable versions from May 2021.
But I have same bug in both tutorials. Bellow commands are from the first tutorial. When I prepare docker images with models and run
$ kubectl apply -f torchserve-custom.yaml

command.  
I see output like
inferenceservice.serving.kubeflow.org/torchserve-custom created

But I can not run a prediction, because service I get 404 not found. 
When I run
$ kubectl get pods --all-namespaces

I do not see any new pods. 
But I can deleted service with
 $ kubectl delete -f torchserve-custom

When I have followed other tutorials like: https://github.com/kubeflow/kfserving/tree/master/docs/samples/v1beta1/torchserve everything worked fine and I could run predictions.
Why can`t I run a prediction?
Why any new pods are created?
How to setup serving in kfserving using docker image, if the above tutorials did not worked?

It turned out that my local docker registry wasn't visible from kubernetes. kubectl get events shows InternalError &quot;Unable to fetch image ... &quot;
