Kubectl connectivity issue

2/9/2019

I installed first ectd, kubeapiserver and kubelet using systemd service. The services are running fine and listening to all required ports.

When I run kubectl cluster-info , I get below output

Kubernetes master is running at http://localhost:8080

When I run kubectl get componentstatuses, then I get below output

etcd-0               Healthy     {"health": "true"}

But running kubectl get nodes , I get below error

Error from server (ServerTimeout): the server cannot complete the requested operation at this time, try again later (get nodes)

Can anybody help me out on this.

What is the status of controller manager and scheduler. Do you see them listed as Healthy when you run the below command

kubectl get cs

Your missing kubeconfig file. kubectl looks config file in this location $HOME/.kube/config

Part of install you can copy config file like this on master node.

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
