Today, the following error occurred when running the command [kubectl] command on the node node of Kubernetes

[root@k8s-node02] # kubectl-s 10.0.0.31 get nodesThe connection to the server 8080 was refused-did you specify the right host or port?

The reason for this problem is that the kubectl command needs to be run using kubernetes-admin. As a solution, copy the / etc/kubernetes/admin.conf file from the master node to the same directory as the slave node node, and then configure the environment variables:

Effective immediately

# echo "export KUBECONFIG=/etc/kubernetes/admin.conf" > > ~ / .bash_profile

The first attempt to run the kubectl command was successful.

Here we will find why we do not need to specify the api-server address to execute the relevant commands directly, that is because the admin.conf configuration file we just copied from the master node stores the configuration related to K8s user rights!
