How Do I Build an Aws Native Iam Instanceprofile With Pulumi?

Introduction

In this guide, we will demonstrate how to create an AWS IAM Instance Profile using Pulumi in TypeScript. An IAM Instance Profile is a container for an IAM role that you can use to pass role information to an EC2 instance when the instance starts. This is particularly useful for granting permissions to applications running on EC2 instances. The key services involved in this solution are AWS IAM and AWS EC2.

Step-by-Step Explanation

Step 1: Set Up Pulumi Project

First, set up a new Pulumi project. You can do this by running pulumi new typescript in your terminal. This will create a new Pulumi project with the necessary configuration files.

Step 2: Install AWS Native Provider

Next, install the AWS Native provider for Pulumi by running npm install @pulumi/aws-native.

Step 3: Create IAM Role

Create an IAM role that will be associated with the instance profile. This role will have a trust policy that allows EC2 instances to assume the role.

Step 4: Attach Policies to IAM Role

Attach the necessary policies to the IAM role. These policies define the permissions that the role will have.

Step 5: Create IAM Instance Profile

Create the IAM instance profile and associate it with the IAM role created in the previous steps.

Step 6: Export the Instance Profile Name

Finally, export the name of the IAM instance profile so that it can be used in other parts of your Pulumi program.

Key Points

• An IAM Instance Profile is used to pass role information to an EC2 instance.
• The IAM role must have a trust policy that allows EC2 instances to assume the role.
• Policies attached to the IAM role define the permissions for the role.
• The IAM instance profile is created and associated with the IAM role.

Conclusion

In this guide, we have shown how to create an AWS IAM Instance Profile using Pulumi in TypeScript. By following the steps outlined above, you can easily manage IAM roles and instance profiles in your AWS environment using Pulumi. This approach provides a programmatic way to handle IAM resources, making it easier to automate and manage your infrastructure.

Full Code Example

import * as awsNative from "@pulumi/aws-native";
import * as pulumi from "@pulumi/pulumi";

// Create IAM Role
const iamRole = new awsNative.iam.Role("myIamRole", {
    assumeRolePolicyDocument: {
        Version: "2012-10-17",
        Statement: [
            {
                Effect: "Allow",
                Principal: {
                    Service: "ec2.amazonaws.com"
                },
                Action: "sts:AssumeRole"
            }
        ]
    }
});

// Attach Policies to IAM Role
const rolePolicy = new awsNative.iam.RolePolicy("myRolePolicy", {
    roleName: iamRole.roleName.apply(name => name || ""),
    policyName: "myPolicy",
    policyDocument: {
        Version: "2012-10-17",
        Statement: [
            {
                Effect: "Allow",
                Action: "s3:ListBucket",
                Resource: "*"
            }
        ]
    }
});

// Create IAM Instance Profile
const instanceProfile = new awsNative.iam.InstanceProfile("myInstanceProfile", {
    roles: iamRole.roleName.apply(name => [name || ""])
});

// Export the Instance Profile Name
export const instanceProfileName = instanceProfile.instanceProfileName;
