Error saying The connection to the server localhost 8080 was refused - did you specify the right host or port

Question

I'm trying to create a simple service on kubernetes

kubectl create serviceaccount dashboard -n default

but it throws the following error

The connection to the server localhost:8080 was refused - did you specify the right host or port?

Answer 1

Run the following command as a normal user

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

Glad to help. :)

i got error in second step :

cp: cannot stat '/etc/kubernetes/admin.conf': No such file or directory

---

Try running these commands,
mkdir ~/.kube
vim ~/.kube/config
and copy the config file from mster node to nodes config file.

This did not work for me

Try to restart your cluster. Or check the configuration file.

$ kubectl config view

thanks , it worked.

I had the exact same error when I was trying to create a cluster on GCP. This is how I got it sorted:

• Log in to Google Cloud Platform
• Navigate to Container Engine Google Cloud Platform, Container Engine
• Click CONNECT on Cluster
• Use login Credentials to access Cluster [NAME] in your Terminal

Answer 3

Try using --server to specify your master:

kubectl --server=16.187.189.90:8080 get pod -o wide

Answer 4

I was trying to get status from a remote system using ansible and I was facing the same issue.
I tried and it worked.

kubectl --kubeconfig ./admin.conf get pods --all-namespaces -o wide
