i/o timeout ImagePullBackOff issue on minikube docker image for pod on fedora32

I am getting ImagePullBackOff error when I pull images from docker fro kubernates pods. I am using Fedora32 and running a minikube on docker.

In the above containers you can see minikube running.

This is what is showing when I see the pods.

[[email protected] simplek8s]$ **minikube ssh**
[email protected]:~$ cat /etc/resolv.conf
options ndots:0
[email protected]:~$ **curl google.com**
curl: (6) **Could not resolve host: google.com**

Clearly the pods are not able to access the internet to pull images. looks like I am missing some dns config to make the minikube pull images from internet.Help me resolve this.
