# Lab 3: Multi Master K3s kubeconfig files for smooth accessibility

Scenario:

We have multiple master nodes and we want to ensure that our operation using `kubectl` in our local machine is smooth and uninterrupted.

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

<figure><img src="/files/imnuzcUgGoqg4Qvzxya3" alt=""><figcaption><p>k3s-master-node0* is the file that contains the configuration data required to access the Kubernetes clusters</p></figcaption></figure>

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:

<pre class="language-bash"><code class="lang-bash"><strong>#My Onprem K8s master nodes
</strong><strong>export CONFIG_K3S_MASTER_NODE01=$HOME/.kube/k3s-master-node01
</strong>export CONFIG_K3S_MASTER_NODE02=$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
</code></pre>

Finally, you may get the results just like below:
