Create Cluster
eksctl create cluster –name=eksdemo1 –region=us-east-1 –zones=us-east-1a,us-east-1b –without-nodegroup
Get List of clusters
eksctl get cluster
Step-02: Create & Associate IAM OIDC Provider for our EKS Cluster
To enable and use AWS IAM roles for Kubernetes service accounts on our EKS cluster, we must create & associate OIDC identity provider.
To do so using eksctl we can use the below command.
Use latest eksctl version (as on today the latest version is 0.21.0)
Template
eksctl utils associate-iam-oidc-provider
–region region-code
–cluster
–approve
Replace with region & cluster name
eksctl utils associate-iam-oidc-provider –region us-east-1 –cluster eksdemo1 –approve
Step-03: Create EC2 Keypair
Create a new EC2 Keypair with name as kube-demo
This keypair we will use it when creating the EKS NodeGroup.
This will help us to login to the EKS Worker Nodes using Terminal.
Step-04: Create Node Group with additional Add-Ons in Public Subnets
These add-ons will create the respective IAM policies for us automatically within our Node Group role.
Create Public Node Group
eksctl create nodegroup –cluster=eksdemo1
–region=us-east-1
–name=eksdemo1-ng-public1
–node-type=t3.medium
–nodes=2
–nodes-min=2
–nodes-max=4
–node-volume-size=20
–ssh-access
–ssh-public-key=kube-demo
–managed
–asg-access
–external-dns-access
–full-ecr-access
–appmesh-access
–alb-ingress-access
eksctl create nodegroup –cluster=eksdemo1 –region=us-east-1 –name=eksdemo1-ng-public1 –node-type=t3.medium –nodes=2 –nodes-min=2 –nodes-max=4 –node-volume-size=20 –ssh-access –ssh-public-key=ekc-ecs-demo-2022 –managed –asg-access –external-dns-access –full-ecr-access –appmesh-access –alb-ingress-access
Step-05: Verify Cluster & Nodes
List EKS clusters
eksctl get cluster
List NodeGroups in a cluster
eksctl get nodegroup –cluster=
List Nodes in current kubernetes cluster
kubectl get nodes -o wide
Our kubectl context should be automatically changed to new cluster
kubectl config view –minify
