Access Kubernetes

EKS-D comes with its own version of Kubectl to access Kubernetes. Below we will cover 2 different forms of access to view the "nodes" and "services":

Conventional

eks kubectl get nodes
Enter fullscreen mode Exit fullscreen mode 
NAME           STATUS   ROLES    AGE   VERSION
myuser         Ready    <none>   33m   v1.18.9-eks-1-18-1
Enter fullscreen mode Exit fullscreen mode 
eks kubectl get services
Enter fullscreen mode Exit fullscreen mode 
NAME         TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.152.183.1   <none>        443/TCP   33m
Enter fullscreen mode Exit fullscreen mode

Recommended

kubectl get nodes
Enter fullscreen mode Exit fullscreen mode 
NAME           STATUS   ROLES    AGE   VERSION
myuser         Ready    <none>   33m   v1.18.9-eks-1-18-1
Enter fullscreen mode Exit fullscreen mode 
kubectl get services
Enter fullscreen mode Exit fullscreen mode 
NAME         TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.152.183.1   <none>        443/TCP   33m
Enter fullscreen mode Exit fullscreen mode

Note: As shown, the 2 forms have the same result, but from this point on we will only use the "Recommended" with Kubectl.

Deploy a test application 

kubectl create deployment nginx --image=nginx
Enter fullscreen mode Exit fullscreen mode 
deployment.apps/nginx created
Enter fullscreen mode Exit fullscreen mode 
kubectl get pods
Enter fullscreen mode Exit fullscreen mode 
NAME                    READY   STATUS    RESTARTS   AGE
nginx-f89759699-2w75l   1/1     Running   0          33s
Enter fullscreen mode Exit fullscreen mode

Starting and stopping EKS-D

EKS-D will continue to run until you decide to stop it. You can stop and start with the commands below:

sudo eks stop
Enter fullscreen mode Exit fullscreen mode 
Stopped.
Enter fullscreen mode Exit fullscreen mode 
sudo eks start
Enter fullscreen mode Exit fullscreen mode 
Started.
Enter fullscreen mode Exit fullscreen mode
