| With the recent upgrade of base image of ghcr.io/jenkins-x/jx-boot:3.2.338 to alpine linux v3.15 in some of the local providers like minikube, the pod's DNS nameserver is not able to resolve DNS hostname outside k8s cluster like github.com. | ||

| To resolve this issue you need to add [custom dnspolicy](https://kubernetes.io/docs/concepts/services-networking/dns-pod-service/#pod-s-dns-policy) on your local cluster repository in below files with this change | ||

Is it possible to change the dns settings in the minikube cluster itself?

With further testing, I found some more bugs and above solution is not enough. I'll work upon it in my free time. As of now please do not merge this PR.
