How to Deploy Apps to Amazon EKS: A Step-by-Step Guide
Introduction to Deploying Apps on Amazon EKS
Amazon Elastic Kubernetes Service (EKS) is a managed Kubernetes service that simplifies running Kubernetes on AWS without the need to install and operate your own control plane or nodes.
Prerequisites
- Amazon AWS account.
- Kubectl installed on your local machine.
- A VPC configured for your EKS cluster.
- Node IAM role with necessary permissions.
Step-by-Step Deployment Guide
Step 1: Setup Your EKS Cluster
Start by navigating to the AWS Management Console. Go to Amazon EKS (Official site) and select ‘Create Cluster’.
# EKS Cluster creation using AWS CLI
aws eks create-cluster \
--region region-code \
--name cluster-name \
--role-arn arn:aws:iam:::role/ \
--resources-vpc-config subnetIds=subnet-id1,subnet-id2This initiates your cluster in the specified region.
Step 2: Configure kubectl for EKS
Ensure kubectl is pointing to your EKS cluster by using:
aws eks --region region-code update-kubeconfig --name cluster-nameStep 3: Deploy Your App
Create deployment.yml for your app:
apiVersion: apps/v1
kind: Deployment
metadata:
name: my-app\tspec:
replicas: 3\ttemplate:
metadata:
labels:
app: my-app
spec:
containers:
- name: my-app
image: my-app-image:latest
Apply the configuration using:
kubectl apply -f deployment.ymlTroubleshooting
- Verify if all the nodes are running using
kubectl get nodes. - Ensure
aws-iam-authenticatoris properly installed if facing authentication issues. - Check pod logs with
kubectl logs pod-namefor debugging.
Summary Checklist
- Set up AWS CLI and kubectl.
- Create and configure an EKS cluster.
- Deploy your app using Kubernetes manifests.
By following this guide, you should now be able to deploy applications on Amazon EKS effectively. For more cloud-related services, you might find our guide on how to install Amazon EKS helpful.
