Using aws amp with account

Question

Pulumi · Accepted Answer

When working with AWS and Pulumi, one of the services you might encounter is the Amazon Managed Service for Prometheus (AMP), which is useful for monitoring and alerting purposes in the cloud infrastructure. To set up an AWS AMP workspace with Pulumi, we'll need to use the `aws.amp.Workspace` resource from the AWS Pulumi provider. Similarly, for handling AWS accounts, we can use resources from the `aws-native` or `aws-iam` packages depending on the specific needs.

Let's illustrate this with a Pulumi program that sets up an AMP workspace and configures an AWS IAM role for using it. This program assumes that you already have an AWS account set up and authenticated with the necessary permissions to create these resources.

The program will:
- Create an AMP workspace.
- Set up an AWS IAM role with a policy granting permissions necessary for an Amazon Managed Service for Prometheus workspace.

Here's a step-by-step walkthrough of the TypeScript program to accomplish this:

1. **Setting up an AMP workspace**: This involves the creation of a Prometheus workspace using the `aws.amp.Workspace` resource. We define an AWS AMP workspace giving it a set of tags for identification.

2. **Creating an IAM role and policy**: To interact with AMP, we'll need an IAM role that has the necessary permissions. We'll create an IAM role using the `aws.iam.Role` resource and attach a policy to it using `aws.iam.Policy` and `aws.iam.RolePolicyAttachment`. The policy will include permissions to allow the necessary AMP actions (like `amp:CreateWorkspace`, `amp:DescribeWorkspace`, etc.).

Let's write the code to set up these resources:

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

// Create an AMP workspace
const ampWorkspace = new aws.amp.Workspace("myAmpWorkspace", {
    tags: {
        Environment: "development",
    }
});

// Create an IAM role for AMP access
const ampRole = new iam.Role("ampRole", {
    assumeRolePolicy: JSON.stringify({
        Version: "2012-10-17",
        Statement: [{
            Action: "sts:AssumeRole",
            Effect: "Allow",
            Principal: {
                Service: "amp.amazonaws.com"
            }
        }],
    }),
    tags: {
        Environment: "development"
    }
});

// Define the permissions policy for the role
const ampPolicy = new iam.Policy("ampPolicy", {
    policy: pulumi.interpolate`{
        "Version": "2012-10-17",
        "Statement": [{
            "Effect": "Allow",
            "Action": [
                "amp:CreateWorkspace",
                "amp:DescribeWorkspace",
                // ... Add additional AMP permissions as required ...
            ],
            "Resource": "*"
        }]
    }`
});

// Attach the policy to the role
const rolePolicyAttachment = new iam.RolePolicyAttachment("ampRolePolicyAttachment", {
    role: ampRole.name,
    policyArn: ampPolicy.arn
});

// Export the AMP workspace ID and IAM role ARN
export const ampWorkspaceId = ampWorkspace.id;
export const ampRoleArn = ampRole.arn;
```

In this program:
- `aws.amp.Workspace`: This is the Pulumi resource for creating an AMP workspace. We add a tag to mark the environment as `development`. [AMP Workspace API Documentation](https://www.pulumi.com/registry/packages/aws/api-docs/amp/workspace/)
- `iam.Role`: This defines an IAM role within AWS. The `assumeRolePolicy` specifies that the principal (AMP service in this case) is allowed to assume the role. [IAM Role Documentation](https://www.pulumi.com/registry/packages/aws/api-docs/iam/role/)
- `iam.Policy`: This outlines the permissions that any principal assuming the `ampRole` will have. We've allowed actions for creating and describing the AMP workspace. You might need to add more permissions based on your use case. [IAM Policy Documentation](https://www.pulumi.com/registry/packages/aws/api-docs/iam/policy/)
- `iam.RolePolicyAttachment`: This attaches the defined policy to the role we created earlier, tying together the permissions with the role. [IAM RolePolicyAttachment Documentation](https://www.pulumi.com/registry/packages/aws/api-docs/iam/rolepolicyattachment/)
- `export`: These lines are making the workspace ID and IAM role ARN available as stack outputs, which can be handy for reference or automation purposes.

Run this Pulumi program by saving the code to a file with a `.ts` extension and using the Pulumi CLI to create and apply a new stack. Make sure to have the AWS CLI configured with appropriate credentials before running the Pulumi commands.
