What is @aws-cdk/aws-iam?

@aws-cdk/aws-iam is an AWS Cloud Development Kit (CDK) library that allows you to define AWS Identity and Access Management (IAM) resources in your CDK applications. This package provides constructs for creating and managing IAM roles, users, policies, and groups, enabling you to manage permissions and access control in your AWS environment programmatically.

What are @aws-cdk/aws-iam's main functionalities?

Create IAM Role

This code sample demonstrates how to create an IAM role that can be assumed by EC2 instances and has read-only access to Amazon S3.

const iam = require('@aws-cdk/aws-iam');
const cdk = require('@aws-cdk/core');

class MyStack extends cdk.Stack {
  constructor(scope, id, props) {
    super(scope, id, props);

    new iam.Role(this, 'MyRole', {
      assumedBy: new iam.ServicePrincipal('ec2.amazonaws.com'),
      managedPolicies: [
        iam.ManagedPolicy.fromAwsManagedPolicyName('AmazonS3ReadOnlyAccess')
      ]
    });
  }
}

const app = new cdk.App();
new MyStack(app, 'MyStack');

Create IAM User

This code sample demonstrates how to create an IAM user with administrator access.

const iam = require('@aws-cdk/aws-iam');
const cdk = require('@aws-cdk/core');

class MyStack extends cdk.Stack {
  constructor(scope, id, props) {
    super(scope, id, props);

    new iam.User(this, 'MyUser', {
      userName: 'my-user',
      managedPolicies: [
        iam.ManagedPolicy.fromAwsManagedPolicyName('AdministratorAccess')
      ]
    });
  }
}

const app = new cdk.App();
new MyStack(app, 'MyStack');

Attach Inline Policy to Role

This code sample demonstrates how to create an IAM role and attach an inline policy that allows listing objects in a specific S3 bucket.

const iam = require('@aws-cdk/aws-iam');
const cdk = require('@aws-cdk/core');

class MyStack extends cdk.Stack {
  constructor(scope, id, props) {
    super(scope, id, props);

    const role = new iam.Role(this, 'MyRole', {
      assumedBy: new iam.ServicePrincipal('lambda.amazonaws.com')
    });

    role.addToPolicy(new iam.PolicyStatement({
      actions: ['s3:ListBucket'],
      resources: ['arn:aws:s3:::my-bucket']
    }));
  }
}

const app = new cdk.App();
new MyStack(app, 'MyStack');
