Module 2 - Create an EKS cluster

For EKS, the Calico OSS can be used as a CNI, or you can make use of the AWS VPC networking as CNI and have Calico only as a plugin for the security policies.

We will use the second approach during this workshop. Please, find below an example on how to create a two nodes cluster with an small footprint, but feel free to create your EKS cluster with the parameters you prefer. Do not forget to include the region if different than the default on your account.

export CLUSTERNAME=tigera-workshop
export REGION=ca-central-1
export VERSION=1.28
# 
echo "# Start Lab Params" > ~/labVars.env
echo export CLUSTERNAME=$CLUSTERNAME >> ~/labVars.env
echo export REGION=$REGION >> ~/labVars.env
#
eksctl create cluster --name $CLUSTERNAME --version $VERSION  --region $REGION --node-type m5.xlarge

  • View EKS cluster.

    Once cluster is created you can list it using eksctl.

    eksctl get cluster $CLUSTERNAME --region $REGION

  • Test access to EKS cluster with kubectl

    Once the EKS cluster is provisioned with eksctl tool, the kubeconfig file would be placed into ~/.kube/config path. The kubectl CLI looks for kubeconfig at ~/.kube/config path or into KUBECONFIG env var.

    # verify kubeconfig file path
ls ~/.kube/config
# test cluster connection
kubectl get nodes

    You should get the output with nodes as Ready

    NAME                                              STATUS   ROLES    AGE     VERSION
ip-192-168-20-189.ca-central-1.compute.internal   Ready    <none>   3m48s   v1.27.9-eks-5e0fdde
ip-192-168-69-126.ca-central-1.compute.internal   Ready    <none>   3m47s   v1.27.9-eks-5e0fdde

    Get all pods and ensure they are in Running state with kubectl get pods -A:

    NAMESPACE     NAME                       READY   STATUS    RESTARTS   AGE
kube-system   aws-node-6qr7g             2/2     Running   0          5m2s
kube-system   aws-node-rgr89             2/2     Running   0          5m1s
kube-system   coredns-797959bcdb-7st4r   1/1     Running   0          10m
kube-system   coredns-797959bcdb-gzzfj   1/1     Running   0          10m
kube-system   kube-proxy-6bnmp           1/1     Running   0          5m2s
kube-system   kube-proxy-qc5b5           1/1     Running   0          5m1s
