Introduction to AWS CloudFormation

Infrastructure as code (IaC) service that helps you model and set up your AWS resources.

AWS CloudFormation is a service that helps you model and set up your AWS resources so that you can spend less time managing those resources and more time focusing on your applications that run in AWS.

Creating your first stack

In your favorite IDE create a YML file as shown below, but you may use JSON formatting if you wish.

Visual Studio CloudFormation plugin.

Is a good idea to install one of the Cloudformation plug-ins avilable, I’m using Visual Studio Code :-).

bucket.yml

AWSTemplateFormatVersion: "2010-09-09"
Description: This is my first bucket
Resources:
  MyBucket:
    Type: AWS::S3::Bucket

This simple template will create a bucket, for that purpose we use the awscli.

If you don´t have the awscli installed please refer to this guide.

$ aws cloudformation create-stack \
                     --stack-name mybucket\
                     --template-body file://bucket.yml
