Hi all,

I have just started Kubernetes, I installed it from the Kubernetes document. Getting below error

[email protected]:~# kubectl get node
The connection to the server localhost:8080 was refused - did you specify the right host or port?

@kanishk Pandey looks like your your kube-apiserver is not able to come up. please try to check the logs in the below sample path. eg: (/var/log/pods/kube-system-kube-apiserver…/kube-apiserver/3.log)

todoriri:
isn’t that due to missing config in $HOME/.kube/config ?

After installing the cluster, did you run the below in order to set the kubelet config?

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

kanishk Pandey:
@unnivkn /etc/kubernetes/admin.conf has not been created in my centos-7 machine
