Terraform module for simplified management of Kubernetes servers using EKS

🔆 Highlights

• EKS Cluster AWS managed Kubernetes cluster of master servers
• AutoScaling Group contains 2 m4.large instances based on the latest EKS Amazon Linux 2 AMI
• Associated VPC, Internet Gateway, Security Groups, and Subnets Operator managed networking resources for the EKS Cluster and worker node instances
• Associated IAM Roles and Policies Operator managed access resources for EKS and worker node instances

🎨 Usage

module "eks" {
  source             = "./terraform-aws-eks"
  cluster-name       = "devopswhizz"
  aws-region         = "us-east1"
  node-instance-type = "m4.xlarge"
  desired-capacity   = "2"
  max-size           = "4"
  min-size           = "2"
}

🔰Getting Started

Follow the steps below to get started

🔨 Setting Up Kubectl

Create a kubeconfig file for manging the EKS Cluster.

Login to your kubectl node and insert the codeblock to .kube/config

apiVersion: v1
clusters:
- cluster:
    server: EKS_ENDPOINT_URL
    certificate-authority-data: BASE64_ENCODED_CA_CERT   
  name: kubernetes
contexts:
- context:
    cluster: kubernetes
    user: aws
  name: aws
current-context: aws
kind: Config
preferences: {}
users:
- name: aws
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1alpha1
      command: heptio-authenticator-aws
      args:
        - "token"
        - "-i"
        - "CLUSTER_NAME"
        - "-r"
        - ""

Replace EKS_ENDPOINT_URL with your EKS Endpoint URL, BASE64_ENCODED_CA_CERT with certificateAuthority and CLUSTER_NAME with EKS Cluster name.

Save the configuration file and execute following commands to use it.

export KUBECONFIG=$KUBECONFIG:~/.kube/config

echo 'export KUBECONFIG=$KUBECONFIG:~/.kube/config' >> ~/.bashrc

Now test your configuration

kubectl get all

If everything is fine, you will get your cluster details :)
