eksctl: deploy the cluster

 Just to remember what I did long time ago.

First make sure you have kubectl installed.

alejandrogarcia@MacBook-Air-de-Alejandro Downloads % sudo port install kubectl-1.31

  kubectl-1.31 has the following notes:

    To make this the default kubectl run:

        sudo port select --set kubectl kubectl1.31

Make default kubectl:

alejandrogarcia@MacBook-Air-de-Alejandro Downloads % sudo port select --set kubectl kubectl1.31

Selecting 'kubectl1.31' for 'kubectl' succeeded. 'kubectl1.31' is now active.

Then, create the cluster with eksctl:

alejandrogarcia@MacBook-Air-de-Alejandro ~ % eksctl create cluster -n cluster1 --nodegroup-name ng1 --region us-east-1 --node-type t2.micro --nodes 2

You can see the nodes running:

alejandrogarcia@MacBook-Air-de-Alejandro ~ % kubectl get nodes

ip-192-168-54-140.ec2.internal   Ready    <none>   5m47s   v1.30.4-eks-a737599

Just to test a pod in the cluster:

alejandrogarcia@MacBook-Air-de-Alejandro nginx-with-volume % kubectl apply -f 01-pod.yaml 

pod/nginx-01 created

You can see the cluster creating the pod:

alejandrogarcia@MacBook-Air-de-Alejandro nginx-with-volume % kubectl get all
