In the modern DevOps landscape, managing permissions and roles in AWS efficiently is key to maintaining a secure cloud environment. Enter IAMy—a powerful tool that helps you dump and load your AWS IAM configuration into YAML files, making your management process smoother and more concise.

What is IAMy?

IAMy allows you to adopt an Infrastructure as Code approach to manage your AWS IAM configuration. Imagine you’re using a recipe book for your favorite dish; IAMy serves as that book but for your AWS configurations. You can track changes via a GitHub repository using a pull request model, making your IAM management organized and version-controlled.

How IAMy Works

IAMy comes equipped with two primary commands: pull and push.

• Pull: This command syncs IAM users, groups, and policies from AWS to your local YAML files.
• Push: This command syncs the modifications from your YAML files back to AWS.

What’s particularly useful about the push command is that it generates an execution plan as AWS CLI commands. Think of it like a checklist that ensures you know exactly what will happen before initiating any changes. You can pick and choose what to execute, giving you complete control over your AWS environment.

Getting Started with IAMy

To start using IAMy, follow these simple steps:

• Install IAMy on macOS using the command: brew install iamy
• Alternatively, you can install it via the Go toolchain with: go get -u github.com/99designs/iamy
• Before using IAMy, ensure you have the AWS CLI tool installed, as it is crucial for running IAMy commands.
• IAMy uses the same AWS environment variables as the AWS CLI for configuration.
• You might find aws-vault handy for managing your AWS credentials.

Example Usage

Here’s how you might interact with IAMy through the command line:

bash
$ iamy pull
$ find ..myaccount-123456789iamuserjoe.yml
$ mkdir -p myaccount-123456789iamuserfoo
$ touch myaccount-123456789iamuserfoobar.baz
$ cat << EOD > myaccount-123456789iamuserbilly.blogs
Policies:
  - arn:aws:iam::aws:policy/ReadOnly
EOD
$ iamy push
Commands to push changes to AWS:
    aws iam create-user --path foo --user-name bar.baz
    aws iam create-user --user-name billy.blogs
    aws iam attach-user-policy --user-name billy.blogs --policy-arn arn:aws:iam::aws:policy/ReadOnly
Exec all aws commands? (y/N) y
aws iam create-user --path foo --user-name bar.baz
aws iam create-user --user-name billy.blogs
aws iam attach-user-policy --user-name billy.blogs --policy-arn arn:aws:iam::aws:policy/ReadOnly

Accurate CloudFormation Matching

IAMy automatically uses a heuristic to determine if a resource is managed by CloudFormation (e.g., checking ID patterns). However, if you want more precise results, you can run it with the --accurate-cfn option. This could be likened to using a detailed map instead of a rough sketch—more accurate but takes a bit longer to process!

Troubleshooting

If you encounter any issues while using IAMy, consider the following troubleshooting tips:

• Ensure that your AWS CLI is set up correctly and that you have the necessary permissions to manage IAM resources.
• If IAMy returns errors, check your YAML syntax; even a small mistake can cause issues.
• For any connectivity issues, ensure your AWS environment variables are properly configured.
• If errors persist, consider reviewing IAMy’s GitHub repository for any open issues or documentation updates.
