The connection to the server localhost:8080 was refused - did you specify the right host or port? Solution: To start using your cluster, you need to run the following as a regular user:
[vagrant@m1-centos cka]$ mkdir -p $HOME/.kube
[vagrant@m1-centos cka]$ sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
[vagrant@m1-centos cka]$ sudo chown $(id -u):$(id -g) $HOME/.kube/config

[vagrant@m1-centos cka]$ kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"
[vagrant@m1-centos cka]$ kubectl get pods --all-namespaces
