Using aws rolesanywhere with ses-service

Question

Pulumi · Accepted Answer

To integrate AWS Roles Anywhere with the SES service using Pulumi, you'll need to configure an SES domain identity and then create a Roles Anywhere profile that will allow the SES service to assume an IAM role with the necessary permissions for sending emails.

Here's how you would do it step by step:

1. **Create an SES Domain Identity**: This identity represents your domain and will be used to send emails. Before you can send an email using SES, you need to prove that you own the domain.

2. **Generate DKIM Settings for the Domain**: This is an important step for email security. DKIM (DomainKeys Identified Mail) is an email authentication method designed to detect forged sender addresses in emails.

3. **Create an IAM Role**: This role will be assumed by SES to send emails on behalf of your domain.

4. **Create a Roles Anywhere Profile**: This profile contains the trust policy and roles that external entities will assume, with the help of Roles Anywhere, to interact with AWS services.

5. **Attach an SES Sending Policy to the IAM Role**: You need to attach a policy that permits the SES service to send emails using your domain.

Let's look at the Pulumi program that accomplishes this:

```typescript
import * as aws from "@pulumi/aws";

// Step 1: Create an SES domain identity
const domain = "yourdomain.com"; // Replace with your domain
const sesDomainIdentity = new aws.ses.DomainIdentity("sesDomainIdentity", {
    domain: domain,
});

// Step 2: Generate DKIM settings for your domain
const sesDomainDkim = new aws.ses.DomainDkim("sesDomainDkim", {
    domain: sesDomainIdentity.domain,
}, { dependsOn: [sesDomainIdentity] });

// Step 3: Create an IAM Role that SES can assume to send emails
const sesSendingRole = new aws.iam.Role("sesSendingRole", {
    assumeRolePolicy: JSON.stringify({
        Version: "2012-10-17",
        Statement: [{
            Action: "sts:AssumeRole",
            Effect: "Allow",
            Principal: {
                Service: "ses.amazonaws.com",
            },
        }],
    }),
});

// Attach a policy to the IAM Role that allows sending SES emails
const policyAttachment = new aws.iam.RolePolicyAttachment("ses-send-email", {
    role: sesSendingRole.name,
    policyArn: "arn:aws:iam::aws:policy/AmazonSESFullAccess",
});

// Step 4: Create a Roles Anywhere Profile
const sesRolesAnywhereProfile = new aws.rolesanywhere.Profile("sesRolesAnywhereProfile", {
    roleArns: [sesSendingRole.arn],
    durationSeconds: 3600, // The duration, in seconds, for the assumed role session
    sessionPolicy: sesSendingRole.assumeRolePolicy,
});

// Output the SES domain verification details and DKIM tokens
export const verificationToken = sesDomainIdentity.verificationToken;
export const dkimTokens = sesDomainDkim.dkimTokens;

```

In this program:
- Replace `"yourdomain.com"` with your own domain.
- The SES domain identity is created and verified.
- DKIM tokens are generated for added email security.
- An IAM role is created with a trust relationship that allows SES to assume the role.
- A policy is attached to the IAM role granting full access to SES features.
- A Roles Anywhere profile is set up, allowing the specified role (`sesSendingRole`) to be assumed with a defined duration and session policy.

It's important to note that this Pulumi code assumes that you've set up the Pulumi AWS provider with the proper configuration to interact with your AWS account. Once you've applied this Pulumi program, you'll need to take the `verificationToken` and the `dkimTokens` and configure them in your DNS provider's settings, following AWS's verification procedures for SES.

As a novice, you should know that the role's permissions should be strictly controlled in a real-world scenario. The policy used in this example grants full access to SES for simplicity. In a production environment, you should grant only the permissions necessary for the operations that need to be performed.
