i'm trying to add spark to minikube with using this blog as tutorial to help me :

The status ImagePullBackOff means that a Pod couldn’t start, because Kubernetes couldn’t pull a container image. The ‘BackOff’ part means that Kubernetes will keep trying to pull the image, with an increasing delay (‘back-off’).

This is a very common reason for ImagePullBackOff since Docker introduced rate limits on Docker Hub. Once you hit your maximum download limit on Docker Hub, you’ll be blocked and this might cause your ImagePullBackOff error. You’ll either need to sign in with an account, or find another place to get your image from.

This error can also happen if your registry requires SSL/TLS authentication, but you don’t trust its certificate. Make sure you follow the instructions to set up TLS authentication.

Failed to pull image ... authentication required

You need to create a Secret for the Docker Registry, or you have been rate-limited from pulling new containers for a while.
