CloudFormation Template Generator

Generate a basic AWS CloudFormation template (YAML or JSON) for a common resource like an S3 bucket or EC2 instance.

Choose a common AWS resource and configure a few parameters - this tool generates a starting CloudFormation template in YAML or JSON.

Validate any generated template with AWS's own tooling, or deploy to a test stack, before using it in production.

Always validate a generated template with `aws cloudformation validate-template` (or deploy to a test stack) before using it in production.

What Is a CloudFormation Template?

An AWS CloudFormation template (in YAML or JSON) declares AWS resources - like S3 buckets, EC2 instances, or security groups - that CloudFormation then creates and manages together as a single "stack".

Why Use This Tool?

CloudFormation's resource properties and required fields vary by resource type and can be easy to miss when starting from a blank template. This tool provides a correctly-structured starting template for common, frequently-requested resources.

How to Use It

  1. Choose a resource type (e.g. S3 bucket, EC2 instance, security group).
  2. Choose YAML or JSON output.
  3. Fill in the relevant parameters.
  4. Copy the generated template.

Limitations

This is a starting template, not a production-validated one - always run it through AWS's own template validation, or deploy to a test stack, before using it against real infrastructure.
