Error while installing Dashboard #2

Hi, I was able to run the vagrant box on Windows. To install Kubernetes Dashboard, I connected to the running box using ssh and used the below command:

    kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/aio/deploy/recommended/kubernetes-dashboard.yaml

And got the below errrors:

    unable to recognize "https://raw.githubusercontent.com/kubernetes/dashboard/master/aio/deploy/recommended/kubernetes-dashboard.yaml": Get http://localhost:8080/api?timeout=32s: dial tcp 10.0.2.15:8080: connect: connection refused

My guess is that the base alpine is not able to dns resolve this address. Being a novice with Alpine and Vagrant, I'd appreciate if you can suggest a way forward.

Thanks.

So its not a DNS issue as ping is successful to the remote address. It's something else with the image.

On further investigation, k3s was crashed. I tried upgrading the downloaded k3s version mentioned in Vagrantfile to 0.2.0. But it still crashed.

Here's the server.log tail:
