Build IAM from Scratch

Steps

Step 0: Detect Environment

Identify the cloud platform and IaC tooling:

• Check for cloud platform: gcloud configs, AWS configs, Azure configs, Terraform files, Pulumi files
• Check for existing IAM: service accounts, roles, policies already defined
• Check for IaC: *.tf (Terraform), Pulumi.*, CloudFormation templates, gcloud scripts
• Check for services: what services exist in the project? (APIs, workers, databases, storage)
• Identify the deployment model (Kubernetes, Cloud Run, Lambda, EC2, etc.)

If the stack is ambiguous, ask the user.
