Not able to configure Kubectl.

[vmudigal]

I refered https://coreos.com/kubernetes/docs/latest/kubernetes-on-vagrant-single.html

I am not able to configure kubectl.

Use a custom KUBECONFIG path
$ kubectl config use-context vagrant-single

error: open /Users/vmudigal/coreos-kubernetes/single-node/kubeconfig.lock: file exists

vmudigal$ kubectl version

How about removing the lock file first?
mv /Users/vmudigal/coreos-kubernetes/single-node/kubeconfig.lock /Users/vmudigal/coreos-kubernetes/single-node/kubeconfig.lock.old

Tried moving the file - but the error is a secondary exception - because kubeconfig.lock is either a transient file during the transaction or it does not exist

The fix is actually to wait until the VM is fully initialized

obrienbiometrics:single-node michaelobrien$ kubectl config use-context vagrant-single
Switched to context "vagrant-single".
