Set Up Kubernetes Cluster on AWS EKS

This page provides step-by-step instructions to provision a Kubernetes cluster on Amazon Elastic Kubernetes Service (EKS) for deploying Nected.

Read the official AWS EKS Setup Guide, to read the steps in more detail.

Prerequisites

Before setting up your Kubernetes cluster, ensure you've installed:

• eksctl: See the official eksctl documentation for installation steps.

• awscli: See the official AWS CLI documentation for installation steps.

Verify your AWS CLI configuration and connectivity by running:

aws sts get-caller-identity

This command confirms your AWS account details and ensures your CLI configuration is correctly set.

Create and Configure the EKS Cluster

Follow these steps to create a Kubernetes cluster on AWS EKS for your Nected deployment:

Step 1: Create an EKS Cluster

Run the following command using eksctl to provision your cluster:

eksctl create cluster --name <CLUSTER_NAME> --region <REGION_NAME> --node-type t2.2xlarge

Replace placeholders as follows:

Placeholder	Description	Example
<CLUSTER_NAME>	Name for your Kubernetes cluster	nected-prod
<REGION_NAME>	AWS Region where your cluster will reside	us-west-2

Step 2: Generate KubeConfig File

To connect to your newly created cluster, generate the KubeConfig file by running:

aws eks update-kubeconfig --region <REGION_NAME> --name <CLUSTER_NAME> --profile <PROFILE_NAME>

Replace placeholders as follows:

Placeholder	Description	Example
<REGION_NAME>	AWS Region of your EKS cluster	us-west-2
<CLUSTER_NAME>	Name of your EKS cluster	nected-prod
<PROFILE_NAME>	AWS CLI profile configured with access to EKS	default

Step 3: Verify Cluster Configuration

Confirm your Kubernetes cluster connection:

kubectl cluster-info

This command displays essential details of your Kubernetes cluster, confirming successful setup.

Define a Storage Class for Persistent Volumes

Nected requires persistent storage. Create a default storage class using Amazon EBS (gp2) with the following steps.

Execute the following command in your terminal:

kubectl apply -f - <<EOF
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: gp2
provisioner: kubernetes.io/aws-ebs
EOF

Set this storage class as the default for your Kubernetes cluster:

kubectl patch storageclass gp2 \\
-p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

Step 4: Attach IAM Policy for EBS Access

Ensure your cluster nodes have the required IAM policy (AmazonEC2FullAccess) to manage EBS volumes:

• Open your AWS IAM Console.

• Navigate to your cluster’s IAM roles (for both cluster and node group).

• Attach the AmazonEC2FullAccess policy to these roles.

This policy is essential for provisioning persistent storage dynamically.
