Building a Complete CI/CD Pipeline for EKS with AWS ECR, CodePipeline, CodeBuild, and Helm

In the world of cloud-native development, automation is essential. With Amazon Web Services (AWS) providing a suite of services like Elastic Kubernetes Service (EKS), Elastic Container Registry (ECR), CodePipeline, CodeBuild, and Helm, you can automate the entire lifecycle of a containerized application — right from building Docker images to deploying them on a Kubernetes cluster.

This blog will walk you through the complete CI/CD pipeline setup for deploying Docker applications on EKS using AWS services, focusing on best practices, security, and scalability.

Overview of the Setup

We will cover:

1. Setting up EKS: Using AWS-managed Kubernetes service.
2. Building and pushing Docker images to ECR: Storing your application images securely.
3. Helm for Kubernetes deployment: Managing complex Kubernetes applications.
4. Automating CI/CD with CodePipeline and CodeBuild: Building and deploying containerized apps automatically.
5. Best practices for securing and scaling: Ensuring your application remains performant and secure.
