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.

Resource

Output Format

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

Choose a resource type (e.g. S3 bucket, EC2 instance, security group).
Choose YAML or JSON output.
Fill in the relevant parameters.
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.

Frequently Asked Questions

Create a stack in the AWS CloudFormation console by uploading the file, or run aws cloudformation deploy --template-file template.yaml --stack-name my-stack.

CloudFormation accepts both. YAML is shorter and supports comments; JSON is easier to generate from code.

The resources it creates, such as EC2 instances, are billed normally by AWS. Delete the stack when you no longer need it to remove those resources.
