Create an LKE Cluster

1. Log into your Linode Cloud Manager account.

2. From the Linode dashboard, click the Create button in the top right-hand side of the screen and select Kubernetes from the dropdown menu.

3. The Create a Kubernetes Cluster page appears. At the top of the page, you are required to select the following options:

   • In the Cluster Label field, provide a name for your cluster. The name must be unique between all of the clusters on your account. This name is how you identify your cluster in the Cloud Manager’s Dashboard.

   • From the Region dropdown menu, select the Region where you would like your cluster to reside.

   • From the Version dropdown menu, select a Kubernetes version to deploy to your cluster.

4. In the Add Node Pools section, select the hardware resources for the Linode worker node(s) that make up your LKE cluster. To the right of each plan, select the plus + and minus - to add or remove a Linode to a node pool one at time.

5. Once you’re satisfied with the number of nodes in a node pool, select Add to include it in your configuration. If you decide that you need more or fewer hardware resources after you deploy your cluster, you can always edit your Node Pool.

6. Once a pool has been added to your configuration, it is listed in the Cluster Summary on the right-hand side of the Cloud Manager detailing your cluster’s hardware resources and monthly cost. Additional pools can be added before finalizing the cluster creation process by repeating the previous step for each additional pool.

7. When you are satisfied with the configuration of your cluster, click the Create Cluster button on the right hand side of the screen. Your cluster’s detail page appears, and your Node Pools are listed on this page. From this page, you can edit your existing Node Pools, access your Kubeconfig file, and view an overview of your cluster’s resource details.

Access and Download your kubeconfig

1. To access your cluster’s kubeconfig, log into your Cloud Manager account and navigate to the Kubernetes section.

2. From the Kubernetes listing page, click on your cluster’s more options ellipsis and select Download kubeconfig. The file is saved to your computer’s Downloads folder.

3. Open a terminal shell and save your kubeconfig file’s path to the $KUBECONFIG environment variable. In the example command, the kubeconfig file is located in the Downloads folder, but you should alter this line with this folder’s location on your computer:

    export KUBECONFIG=~/Downloads/kubeconfig.yaml
   

4. View your cluster’s nodes using kubectl.

    kubectl get nodes
