First, create the necessary kubeconfig files and add the configuration data into it like the following:

k3s-master-node0* is the file that contains the configuration data required to access the Kubernetes clusters

Then we modify our shell profile. Depending on your setup, as for me, I'm using [zsh](https://ohmyz.sh/) as my shell. Therefore, I will modify the `.zshrc` file as below:

#My Onprem K8s master nodes
export CONFIG_K3S_MASTER_NODE01=$HOME/.kube/k3s-master-node01
export CONFIG_K3S_MASTER_NODE02=$HOME/.kube/k3s-master-node02
export CONFIG_K3S_MASTER_NODE03=$HOME/.kube/k3s-master-node03

#Merge all the configs
export KUBECONFIG=$CONFIG_K3S_MASTER_NODE01:$CONFIG_K3S_MASTER_NODE02:$CONFIG_K3S_MASTER_NODE03:$CONFIG_MINIKUBE

Finally, you may get the results just like below:
