EKS- Cluster Lab Setup

 

EKS Lab Setup (using Region Virginia (us-east-1))

For Lab point of view we will setup the environment as per below diagram

Step 1:- Create an IAM user and EKS Role

• Create the user with IAM with console and programmatic and download security credentials with security access id and Access key
• Permission point of view provide EKSFullAccess(There are some set of policies you need to add) and other permission as per the requirement to deal EKS with other services
• Create IAM Role for EKS
  EKS (Allows EKS to manage clusters on your behalf.):- Role name :- AWSServiceRoleForAmazonEKS
  EKS - Cluster AWSClusterRoleForAmazonEKS

Step 2:- Create the ssh key pair

   Create SSH key value pair ( I am creating a key pair as vdevops)

Step 3:- Setup Command line Tools

• Install awscli on Ubuntu Ec2 Instance
  apt install unzip -y
  curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
  unzip awscliv2.zip
  sudo ./aws/install
  export PATH=/usr/local/bin:$PATH
  aws --version
  aws configure (To confiure aws credential with region=us-east-1)
• Install and setup 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
• eksctl version
• 
  
• 
  
• Install and setup kubectl
  curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
  sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl
  kubectl version --client
  

Step 3:- Create first EKS Cluster using eksctl

Create a yaml file to create EKS Cluster ( I have given file name as eks.yaml)

apiVersion: eksctl.io/v1alpha5 kind: ClusterConfig metadata: name: EKS-raman-cluster region: us-east-1 nodeGroups: - name: ng-1 instanceType: t2.small desiredCapacity: 3
volumeSize: 10 ssh: # use existing EC2 key publicKeyName: vdevops 

Step 4:- Run below commands w.r.t eksctl

  # Find the available options for eksctl create cluster command
  eksctl create cluster --help
  # create cluster by using yaml config file (it will take 15-20 mins to create cluster )
  eksctl create cluster -f eks.yaml
  # Post cluster check
   kubectl get nodes
  # check there must be a /root/.kube/config file which refers to EKS Cluster
  
  # get cluster 
      eksctl get cluster
  # get node group details of the cluster
      eksctl get nodegroup --cluster EKS-raman-cluster
