Running on the primary node Kubernetes command] [kubectl following error occurred
[root@k8s-master kubernetes]# kubectl get pod
The connection to the server localhost:8080 was refused - did you specify the right host or port?
This problem occurs because the command requires kubectl kubernetes-admin to run.
Solutions are as follows, copy master node /etc/kubernetes/admin.conf] [files to the same directory from the node, and then configure the environment variables:
main node:
scp -r /etc/kubernetes/admin.conf ${master}:/etc/kubernetes/admin.conf
From the node:
echo “export KUBECONFIG=/etc/kubernetes/admin.conf” >> ~/.bash_profile
source ~/.bash_profile
Example:
Master
$ scp -r /etc/kubernetes/admin.conf ${k8s-node1}:/etc/kubernetes/admin.conf
Worker
$ echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> ~/.bash_profile
$ source ~/.bash_profile
