In this article, we will set up an AWS environment to deploy a Dockerized Spring Boot application in a Kubernetes Cluster with the free tier EC2 instance in a few minutes. Kubernetes can be installed on AWS as explained in the Kubernetes documentation either using conjure-up, Kubernetes Operations (kops), CoreOS Tectonic or kube-aws. Out of those options, I found kops easier to use and it's nicely-designed for customizing the installation, executing upgrades and managing the Kubernetes clusters over time.

Steps to Follow
- First, we need an AWS account and access keys to start with. Login to your AWS console and generate access keys for your user by navigating to Users/Security credentials page.

- Create a new IAM user or use an existing IAM user and grant the following permissions to the newly-created EC2 Instance:
AmazonEC2FullAccess
AmazonRoute53FullAccess
AmazonS3FullAccess
