# Configuring the Kubernetes Client - Remote Access
Run the following commands from the machine which will be your Kubernetes Client
## Download and Install kubectl
### OS X
```
wget https://storage.googleapis.com/kubernetes-release/release/v1.6.0-beta.4/bin/darwin/amd64/kubectl
chmod +x kubectl
sudo mv kubectl /usr/local/bin
```
### Linux
```
wget https://storage.googleapis.com/kubernetes-release/release/v1.6.0-beta.4/bin/linux/amd64/kubectl
chmod +x kubectl
sudo mv kubectl /usr/local/bin
```
## Configure Kubectl
In this section you will configure the kubectl client to point to the [Kubernetes API Server Frontend Load Balancer](04-kubernetes-controller.md#setup-kubernetes-api-server-frontend-load-balancer).
### GCE
```
KUBERNETES_PUBLIC_ADDRESS=$(gcloud compute addresses describe kubernetes \
--format 'value(address)')
```
### AWS
```
KUBERNETES_PUBLIC_ADDRESS=$(aws elb describe-load-balancers \
--load-balancer-name kubernetes | \
jq -r '.LoadBalancerDescriptions[].DNSName')
```
---
Also be sure to locate the CA certificate [created earlier](02-certificate-authority.md). Since we are using self-signed TLS certs we need to trust the CA certificate so we can verify the remote API Servers.
### Build up the kubeconfig entry
The following commands will build up the default kubeconfig file used by kubectl.
```
kubectl config set-cluster kubernetes-the-hard-way \
--certificate-authority=ca.pem \
--embed-certs=true \
--server=https://${KUBERNETES_PUBLIC_ADDRESS}:6443
```
```
kubectl config set-credentials admin \
--client-certificate=admin.pem \
--client-key=admin-key.pem
```
```
kubectl config set-context default-context \
--cluster=kubernetes-the-hard-way \
--user=admin
```
```
kubectl config use-context default-context
```
At this point you should be able to connect securly to the remote API server:
```
kubectl get componentstatuses
```
```
NAME STATUS MESSAGE ERROR
controller-manager Healthy ok
scheduler Healthy ok
etcd-2 Healthy {"health": "true"}
etcd-0 Healthy {"health": "true"}
etcd-1 Healthy {"health": "true"}
```
```
kubectl get nodes
```
```
NAME STATUS AGE
worker0 Ready 7m
worker1 Ready 5m
worker2 Ready 2m
```
