Not able to configure Kubectl. #886

Closed vmudigal closed 7 years ago

vmudigal commented 7 years ago

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 Client Version: version.Info{Major:"1", Minor:"6", GitVersion:"v1.6.1", GitCommit:"b0b7a323cc5a4a2019b2e9520c21c7830b7f708e", GitTreeState:"clean", BuildDate:"2017-04-03T20:44:38Z", GoVersion:"go1.7.5", Compiler:"gc", Platform:"darwin/amd64"} The connection to the server 172.17.4.99:443 was refused - did you specify the right host or port?

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".
