Former2
Generate CloudFormation / Terraform / Troposphere templates from your existing AWS resources
Overview
Former2 allows you to generate Infrastructure-as-Code outputs from your existing resources within your AWS account. By making the relevant calls using the AWS JavaScript SDK, Former2 will scan across your infrastructure and present you with the list of resources for you to choose which to generate outputs for.
Installation
Though some AWS services do not require it, you will need to install the Former2 Helper browser extension in order to have support for all AWS services. The extension exists to bypass a lack of CORS on some services, such as S3 and IAM.
Install Former2 Helper for Google Chrome
Install Former2 Helper for Mozilla Firefox
Install Former2 Helper for Microsoft Edge
Alternatively, you can download and install the extension yourself.
Usage
Visit former2.com to start.
You will need an IAM key pair to authenticate your requests. If you are not planning on importing resources directly, it is recommended that you provide only read access with these credentials and suggest you assign the ReadOnlyAccess policy. If you intend to use the Import feature, you should grant appropriate permissions to create the stack.
Once authenticated you can navigate via the dashboard or sidebar to specific services, select the resources to add to your outputs and finally click the "Generate" button at the top of the screen.
The following outputs are currently supported:
- CloudFormation
- Terraform
- Troposphere
- CDK V1 (Cfn Primitives) - TypeScript, Python, Java, C#
- CDK V2 (Cfn Primitives) - TypeScript, Python, Java, C#
- CDK for Terraform - TypeScript
- Pulumi - TypeScript
- Diagram - embedded version of draw.io
Former2 CLI
A command-line version of Former2 with limited functionality is available for installation. For more information, see the CLI instructions.
LocalStack Support
To enable support for use against LocalStack endpoints, enable the setting in the Settings page, ensure you are using the Former2 Helper extension/add-on, and add the following configuration to LocalStack:
For Google Chrome:
EXTRA_CORS_ALLOWED_ORIGINS=chrome-extension://fhejmeojlbhfhjndnkkleooeejklmigi
For Mozilla Firefox:
EXTRA_CORS_ALLOWED_ORIGINS=moz-extension://853c673f-1bd8-4226-a5ff-f1473f7b3d90
For Microsoft Edge:
EXTRA_CORS_ALLOWED_ORIGINS=extension://okkjnfohglnomdbpimkcdkiojbeiedof
Security
Former2 does not create any resources within your AWS account.
Calls to the AWS service API endpoints are made either directly with the JavaScript SDK or via the browser extension (which also hits endpoints directly). Resource data and your credentials are kept entirely in memory and is never sent over the internet or anywhere else. The credentials are only used to sign requests to AWS endpoints. You should take care to remove any sensitive data (passwords etc.) when sharing your generated code/templates with others.
If you prefer not to use a publicly hosted site to use Former2, you can host your own version by running a HTTP server from the root of the repository. Extension support will also be available if you host on 127.0.0.1 or localhost, otherwise you can modify the extension as needed.
Pricing
Though Former2 is free to access or use locally, some AWS services have small charges associated with API calls so usage may attract an extra couple cents to your AWS bill.
FAQ
Does this replace Console Recorder?
Console Recorder still fills a certain gap and has features this tool does not support (such as Get/List outputs). I'll be maintaining both for as long as I can.
I found an issue / I'm missing an output / Something's wrong. Can you help?
