## プロジェクトの歴史と使われ方

IAMy is a Go command-line tool from 99designs for dumping AWS IAM users, groups, roles, and policies into YAML files and pushing YAML-backed IAM changes back through AWS CLI commands.

### プロジェクトの歴史

The project grew out of the infrastructure-as-code practice of keeping IAM state in a reviewable repository. Its README describes the two-command model: `pull` syncs IAM resources into YAML and `push` turns YAML changes into an execution plan of AWS CLI commands.

### 採用の歴史

IAMy remained a niche AWS operations tool rather than a broad cloud framework. Homebrew and Nix packaging made it easy for Unix-oriented infrastructure teams to install, and the GitHub repository accumulated a modest community of users around the YAML export/import workflow.

### 使われ方

Operators use IAMy when they want AWS IAM represented as ordinary files that can be reviewed in pull requests. The tool deliberately prints AWS CLI commands for `push`, which makes destructive or privilege-changing operations visible before execution.

### パッケージ好きにとっての重要性

For package collectors, IAMy is a compact example of the pre-CloudFormation/Terraform tooling layer around AWS IAM: small Go binaries, YAML state, Homebrew distribution, and explicit links to neighboring tools such as iamer, Terraform, the AWS CLI, and aws-vault.

### タイムライン

- v1.0.0: The repository tagged a 1.0 line after early file-layout work.
- v2.0.0: The release notes describe a layout-changing release that added S3 bucket ACL management and normalized AWS policy documents.
- v2.1.0: The release notes added a dry-run flag, policy and role descriptions, and cleanup for excess policy versions.
- 2021: v2.4.0 added slower but more accurate CloudFormation filtering and fixed IAM role/instance-profile deletion ordering.

### Related projects

- The README names percolate/iamer and Terraform as inspiration or adjacent tools, and it points users to AWS CLI environment variables and 99designs/aws-vault for credential handling.
