How to create a cloud formation template from an existing AWS environment?

Question

I have an existing aws infrastructure with VPC's, subnets, instances,etc. If I need to build the same infrastructure again in future is there any way to create a cloud formation template from the existing infrastructure? Please help.

Answer 1

Check the Github Former project. Former2 can generate not just CloudFormation but Terraform Troposphere templates, and CDK (typescript) from your existing AWS resources

Answer 2

There is stack available in CloudFormation templates named CloudFormer. You can create AWS CloudFormation Templates from Existing AWS Resources by using this stack. Although, as it is in Beta version it might not be supported for all the resources. You can refer document for more information about CloudFormer:
