Installing EKS via cluster config file

Installing eksctl

$ curl --silent --location "https://github.com/weaveworks/eksctl/releases/latest/download/eksctl_$(uname -s)_amd64.tar.gz" | tar xz -C /tmp
$ sudo mv /tmp/eksctl /usr/local/bin

Installing EKS cluster

Create a file called cluster.yaml

cat >cluster.yaml <<EOF
apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig
metadata:
  name: training-cluster
  region: eu-central-1
nodeGroups:
  - name: worker-group
    instanceType: t2.xlarge
    desiredCapacity: 3
    minSize: 3
    maxSize: 5
EOF

Create the cluster

eksctl create cluster -f cluster.yaml

This may take a while (15min). Verify the cluster to see everything is Ready

kubectl get no -o wide

Installing support for Calico Network Security policies

kubectl apply -f https://raw.githubusercontent.com/aws/amazon-vpc-cni-k8s/master/config/master/calico-operator.yaml
kubectl apply -f https://raw.githubusercontent.com/aws/amazon-vpc-cni-k8s/master/config/master/calico-crs.yaml

Check if everything is ready …

kubectl get daemonset calico-node --namespace calico-system

Deleting the EKS cluster

eksctl delete cluster --name training-cluster --region eu-central-1
