☸️ Create EKS Cluster

Run the following command to create an EKS cluster named mycluster in us-east-1:

eksctl create cluster --name mycluster --region us-east-1

eksctl create cluster \
--name mycluster \
--region us-east-1 \
--nodegroup-name mynodes \
--node-type t3.micro \
--nodes 2 \
--nodes-min 2 \
--nodes-max 2 \
--managed

cluster-config.yaml

apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig

metadata:
  name: mycluster
  region: us-east-1

nodeGroups:
  - name: mynodes
    instanceType: t3.small
    desiredCapacity: 2
    minSize: 2
    maxSize: 2
    amiFamily: AmazonLinux2
    ssh:
      allow: true

eksctl create cluster -f cluster-config.yaml

create eks manually

EKS - manually 

1. search eks 
2. create cluster 
3. name cluster - mycluster 
4. create AmazonEKSAutoClusterRole Role
