How does one install the kube-dns addon for minikube?

Question

Can someone please detail the steps necessary to install the kube-dns addon? I\'ve downloaded the nearly 400MB git repo in the previous link and run make as in

This fix is for VirtualBox drivers only - confirm your driver with

cat ~/.minikube/machines/minikube/config.json | grep DriverName

The accepted answer is correct that kube-dns is installed and enabled by default. But it seems to be a common problem that the pods to manage DNS are not created, making it seem that kube-dns has not been installed.

Eg:

$ kubectl get po -n kube-system
kube-addon-manager-minikube   1/1       Running   1          1m

You can confirm kube-dns is installed and enabled (even though not working) with:

$ minikube addons list
- addon-manager: enabled
- dashboard: enabled
- kube-dns: enabled
{snipped}

The underlying problem is VirtualBox related, as described here: https://forums.virtualbox.org/viewtopic.php?f=7&t=50368

Fix:

minikube stop    
VBoxManage modifyvm "VM name" --natdnshostresolver1 on
minikube start

kubectl get all -n kube-system

VM name is probably "minikube". If the last command doesn't return a large list of pods (including kube-dns and kube-dashboard), wait a few moments - I have a few blank results before success.

For Windows users, VBoxManage is installed by default at c:\Program Files\Oracle\VirtualBox

The kube-dns addon should be enabled by default in minikube. You can run kubectl get po -n kube-system to check if the pod the addon-manager launches is there. If you don't see the pod listed, make sure that the addon is enabled in minikube by running minikube addons list and verifying that kube-dns is enabled

Edit: For me kubectl get po -n kube-system is a valid command, here is the output:

$ kubectl get po -n kube-system
NAME                          READY     STATUS    RESTARTS   AGE
kube-addon-manager-minikube   1/1       Running   2          5d
kube-dns-v20-7ddvt            3/3       Running   6          5d
kubernetes-dashboard-rn54g    1/1       Running   2          5d

You can see from this that the kube-dns pods are running correctly. Can you verify that your kube-dns pods are in the Running state?
