Install kubectl

You need to install the kubectl client to your computer before proceeding. Follow the steps corresponding to your computer's operating system.

macOS:

Install via Homebrew:

brew install kubectl

If you don't have Homebrew installed, visit the Homebrew home page for instructions. Alternatively, you can manually install the binary; visit the Kubernetes documentation for instructions.

Linux:

Download the latest kubectl release:

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"

Make the downloaded file executable:
```
chmod +x ./kubectl
```

Move the command into your PATH:

sudo mv ./kubectl /usr/local/bin/kubectl

📘
You can also install kubectl via your package manager; visit the Kubernetes documentation for instructions.

Windows:

Visit the Kubernetes documentation for a link to the most recent Windows release.

Connect to a cluster with kubectl

After you've created your LKE cluster using Cloud Manager, you can begin interacting with and managing your cluster. You connect to it using the kubectl client on your computer. To configure kubectl, download your cluster's kubeconfig file.

Access and download your kubeconfig

Anytime after your cluster is created you can download its kubeconfig. The kubeconfig is a YAML file that will allow you to use kubectl to communicate with your cluster. Here is an example kubeconfig file:

apiVersion: v1
kind: Config
preferences: {}

clusters:
- cluster:
    certificate-authority-data: LS0tLS1CRUd...
    server: https://example.us-central.linodelke.net:443
  name: lke1234

users:
- name: lke1234-admin
  user:
    as-user-extra: {}
    token: LS0tLS1CRUd...

contexts:
- context:
    cluster: lke1234
    namespace: default
    user: lke1234-admin
  name: lke1234-ctx

current-context: lke1234-ctx

This configuration file defines your cluster, users, and contexts.

To access your cluster's kubeconfig, log in to your Cloud Manager account and navigate to the Kubernetes section.
From the Kubernetes listing page, click on your cluster's more options ellipsis and select Download kubeconfig. The file will be saved to your computer's Downloads folder.
📘
Download and view your Kubeconfig from the cluster's details page
You can also download the kubeconfig from the Kubernetes cluster's details page.
1. When viewing the Kubernetes listing page, click on the cluster for which you'd like to download a kubeconfig file.
2. On the cluster's details page, under the kubeconfig section, click the Download icon. The file will be saved to your Downloads folder.
3. To view the contents of your kubeconfig file, click on the View icon. A pane will appear with the contents of your cluster's kubeconfig file.
To improve security, change the kubeconfig.yaml file permissions to be only accessible by the current user:
```
chmod go-r /Downloads/kubeconfig.yaml
```
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
```
📘
It is common practice to store your kubeconfig files in ~/.kube directory. By default, kubectl will search for a kubeconfig file named config that is located in the ~/.kube directory. You can specify other kubeconfig files by setting the $KUBECONFIG environment variable, as done in the step above.
View your cluster's nodes using kubectl.
```
kubectl get nodes
```
📘
If your kubectl commands are not returning the resources and information you expect, then your client may be assigned to the wrong cluster context. Visit our Troubleshooting Kubernetes guide to learn how to switch cluster contexts.

You are now ready to manage your cluster using kubectl. For more information about using kubectl, see Kubernetes' Overview of kubectl guide.

Persist the kubeconfig context

If you create a new terminal window, it does not have access to the context that you specified using the previous instructions. This context information can be made persistent between new terminals by setting the KUBECONFIG environment variable in your shell's configuration file.

📘
If you are using Windows, review the official Kubernetes documentation for how to persist your context.

These instructions persist the context for users of the Bash terminal. They are similar for users of other terminals:

Navigate to the $HOME/.kube directory:
```
cd $HOME/.kube
```
Create a directory called configs within $HOME/.kube. You can use this directory to store your kubeconfig files.
```
mkdir configs
```

Copy your kubeconfig.yaml file to the $HOME/.kube/configs directory.

cp ~/Downloads/kubeconfig.yaml $HOME/.kube/configs/kubeconfig.yaml

📘
Alter the above line with the location of the Downloads folder on your computer.
Optionally, you can give the copied file a different name to help distinguish it from other files in the `configs` directory.

Open up your Bash profile (e.g. ~/.bash_profile) in the text editor of your choice and add your configuration file to the $KUBECONFIG PATH variable.

If an export KUBECONFIG line is already present in the file, append to the end of this line as follows; if it is not present, add this line to the end of your file:
```
export KUBECONFIG=$KUBECONFIG:$HOME/.kube/config:$HOME/.kube/configs/kubeconfig.yaml
```
Close your terminal window and open a new window to receive the changes to the $KUBECONFIG variable.

Use the config get-contexts command for kubectl to view the available cluster contexts:

kubectl config get-contexts

You should see output similar to the following:

CURRENT   NAME          CLUSTER   AUTHINFO        NAMESPACE
*         lke1234-ctx   lke1234   lke1234-admin   default

If your context is not already selected, (denoted by an asterisk in the current column), switch to this context using the config use-context command. Supply the full name of the cluster (including the authorized user and the cluster):
```
kubectl config use-context lke1234-ctx
```
You should see output like the following:
```
Switched to context "lke1234-ctx".
```

You are now ready to interact with your cluster using kubectl. You can test the ability to interact with the cluster by retrieving a list of Pods. Use the get pods command with the -A flag to see all pods running across all namespaces:

kubectl get pods -A

You should see output like the following:

NAMESPACE     NAME                                      READY   STATUS    RESTARTS   AGE
