In this blog post, I will show you how to install Kubernetes cluster on AWS using eksctl
Create Manifest file
Create a file called cluster.yaml
apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig
metadata:
name: zshaik-cluster
region: us-east-1
vpc:
subnets:
public:
us-east-1a: { id: subnet-0fdc9e4b09db39551 }
us-east-1b: { id: subnet-0a0dea9b13c2f97b6 }
nodeGroups:
- name: zshaik-cluster-ng-1
instanceType: t3.medium
desiredCapacity: 3
ssh:
allow: true # will use ~/.ssh/id_rsa.pub as the default ssh key
Install using eksctl
eksctl create cluster -f cluster.yaml
After the successful installation, you should see the below log & cluster be accesible via kubeconfig copied to $USER/.kube/config
eksctl create cluster -f cluster.yaml
