aws-extend-switch-roles VS terraforming

That is really nice! I currently use AWS Extend Switch Roles extension[1] to switch profiles, but an automated way to confine those roles to their own profiles would be very neat.

AWS Extend Switch Roles Chrome browser extension

Use the AWS Extend Switch Roles extension, perhaps: https://github.com/tilfinltd/aws-extend-switch-roles?

I'm a big fan of using the AWS extend switch roles extension which allows you to easily switch AWS roles when using the management console in your browser.

🎚 aws-extend-switch-roles is an extension to Chrome and Firefox that give you show all of the switch roles from a browse menu by loading your AWS configuration.

Terraforming

I would also strongly recommend an iterative triage process: don't feel that you need to solve everything all once. It's a huge amount of progress if you can get to a stage where you understand the relationships between services, have enough monitoring to identify failures, and can iteratively move services to more granular IAM policies even if it's all still running in one big account. Simply using a tool like terraformer or terraforming to move the manual configuration into an IaC workflow is an accomplishment, especially since it helps you both make changes more confidently and identify where new changes are still being made. Depending on the politics, that last part might be important: you'll be unpopular if you take away everyone's rights but you'll probably have better luck first nudging people to make them using a sensible flow rather than by hand.

Haven't tried this but if I ever find myself in your situation I'll give it a spin https://github.com/dtan4/terraforming

There are a couple of tools to automate creating terraform configuration and prepopulate state from existing resources, like terraforming, terraformer or cf-terraforming. But it is still cumbersome and laborious and in my experience, it's usually way easier to just recreate everything within terraform from scratch wherever that's possible.

🧪 Terraforming export existing AWS resources to Terraform style (tf, tfstate).
