# Configuring kubectl for Remote Access
|
|
|
|
In this lab you will generate a kubeconfig file for the `kubectl` command line utility based on the `admin` user credentials.
|
|
|
|
> Run the commands in this lab from the same directory used to generate the admin client certificates.
|
|
|
|
## The Admin Kubernetes Configuration File
|
|
|
|
Each kubeconfig requires a Kubernetes API Server to connect to. To support high availability the IP address assigned to the external load balancer fronting the Kubernetes API Servers will be used.
|
|
|
|
Generate a kubeconfig file suitable for authenticating as the `admin` user:
|
|
|
|
```
|
|
{
|
|
KUBERNETES_LB_ADDRESS=192.168.5.30
|
|
|
|
kubectl config set-cluster kubernetes-the-hard-way \
|
|
--certificate-authority=ca.crt \
|
|
--embed-certs=true \
|
|
--server=https://${KUBERNETES_LB_ADDRESS}:6443
|
|
|
|
kubectl config set-credentials admin \
|
|
--client-certificate=admin.crt \
|
|
--client-key=admin.key
|
|
|
|
kubectl config set-context kubernetes-the-hard-way \
|
|
--cluster=kubernetes-the-hard-way \
|
|
--user=admin
|
|
|
|
kubectl config use-context kubernetes-the-hard-way
|
|
}
|
|
```
|
|
|
|
## Verification
|
|
|
|
Check the health of the remote Kubernetes cluster:
|
|
|
|
```
|
|
kubectl get componentstatuses
|
|
```
|
|
|
|
> output
|
|
|
|
```
|
|
NAME STATUS MESSAGE ERROR
|
|
controller-manager Healthy ok
|
|
scheduler Healthy ok
|
|
etcd-1 Healthy {"health":"true"}
|
|
etcd-0 Healthy {"health":"true"}
|
|
```
|
|
|
|
List the nodes in the remote Kubernetes cluster:
|
|
|
|
```
|
|
kubectl get nodes
|
|
```
|
|
|
|
> output
|
|
|
|
```
|
|
NAME STATUS ROLES AGE VERSION
|
|
worker-1 NotReady <none> 118s v1.13.0
|
|
worker-2 NotReady <none> 118s v1.13.0
|
|
```
|
|
Note: It is OK for the worker node to be in a `NotReady` state. Worker nodes will come into `Ready` state once networking is configured.
