In the previous post, you learnt how to deploy a basic Dockerized Spring Boot application to AWS Fargate. Wouldn’t it be great if this manual configuration could be provisioned from a plain text file which can be part of your version control system? With a single action, all necessary resources are configured in the right order. In this post, you will learn how to create an AWS CloudFormation template. Enjoy!
1. Introduction
It is advised to read the previous post first because in this post, you will execute the identical steps but this time the steps are configured in a CloudFormation template. However, if you already know what AWS Fargate is, it is just fine to skip it and start right away. With CloudFormation, the configuration of your infrastructure can be provisioned easily and the infrastructure can be treated as code. Of course, the provisioning will be easy once you have configured the template correctly. The latter can be quite a challenge, but the AWS documentation and examples will help you along the way. The proof of the pudding is in the eating, so let’s see how the configuration of the previous post, where you deployed a Spring Boot application to AWS Fargate, can be transformed to a CloudFormation template. You will do so step by step because the complete template can be overwhelming at first.
