Please Help If anybody knows anything about this.

Answer 1

It seems to be an issue with the ability to reach container registry or registry in use for your images. Can you try to pull the image manually from the node?

Answer 2

I think your internet connection is slow. The timeout to pull an image is 120 seconds, so kubectl could not pull the image in under 120 seconds.

First, pull the image via Docker

docker image pull ayushftw/nodeapp1:latest

Then load the downloaded image to minikube

minikube image load ayushftw/nodeapp1:latest

And then everything will work because now kubectl will use the image that is stored locally.
