Fetch kubeconfig to access the cluster

export REGION=ap-southeast-1
export CLUSTER_NAME=eks-workshop
aws eks update-kubeconfig --region $REGION --name $CLUSTER_NAME

Check what's inside the cluster

# List all pods in all namespaces
kubectl get pods -A

# List all deployments in kube-system
kubectl get deployment -n kube-system

# List all daemonsets in kube-system
kubectl get daemonset -n kube-system

# List all nodes
kubectl get nodes

Let's try to deploy a simple app

# Create a deployment
kubectl create deployment my-app --image nginx

# Scale the replicas of my-app deployment
kubectl scale deployment/my-app --replicas 2

# Check the pods
kubectl get pods

# Delete the deployment
kubectl delete deployment my-app
