How Do I Integrate PostgreSQL With AWS S3 for Data Exports and Backups Using Pulumi Using TypeScript?

To integrate PostgreSQL with AWS S3 for data exports and backups using Pulumi in TypeScript, we will follow these steps:

1. Set up AWS S3 Bucket: Create an S3 bucket where the PostgreSQL backups will be stored.
2. Set up IAM Role and Policy: Create an IAM role and policy that grants the necessary permissions to access the S3 bucket.
3. Set up PostgreSQL RDS Instance: Create a PostgreSQL RDS instance that will be used for the database.
4. Configure Backup Export: Configure the RDS instance to export backups to the S3 bucket.

We will use Pulumi’s AWS provider to create and manage these resources.

Full Code Example

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

// Create an S3 bucket
const bucket = new aws.s3.Bucket("my-bucket", {
    bucket: "my-postgresql-backups",
});

// Create an IAM role
const role = new aws.iam.Role("my-role", {
    assumeRolePolicy: JSON.stringify({
        Version: "2012-10-17",
        Statement: [
            {
                Action: "sts:AssumeRole",
                Principal: {
                    Service: "rds.amazonaws.com",
                },
                Effect: "Allow",
                Sid: ""
            }
        ]
    })
});

// Create an IAM policy
const policy = new aws.iam.Policy("my-policy", {
    policy: bucket.arn.apply(arn => JSON.stringify({
        Version: "2012-10-17",
        Statement: [
            {
                Action: [
                    "s3:PutObject",
                    "s3:GetObject",
                    "s3:ListBucket"
                ],
                Resource: [
                    `${arn}/*`,
                    arn
                ],
                Effect: "Allow"
            }
        ]
    }))
});

// Attach the policy to the role
const rolePolicyAttachment = new aws.iam.RolePolicyAttachment("my-role-policy-attachment", {
    role: role.name,
    policyArn: policy.arn,
});

// Create a PostgreSQL RDS instance
const dbInstance = new aws.rds.Instance("my-db-instance", {
    engine: "postgres",
    instanceClass: "db.t3.micro",
    allocatedStorage: 20,
    dbName: "mydatabase",
    username: "myusername",
    password: "mypassword",
    skipFinalSnapshot: true,
    backupRetentionPeriod: 7,
    backupWindow: "03:00-06:00",
    vpcSecurityGroupIds: ["sg-12345678"],
});

// Export the RDS instance endpoint
export const dbInstanceEndpoint = dbInstance.endpoint;

// Create an RDS export task to S3
const exportTask = new aws.rds.ExportTask("my-export-task", {
    exportTaskIdentifier: "my-export-task",
    sourceArn: dbInstance.arn,
    s3BucketName: bucket.bucket,
    iamRoleArn: role.arn,
    kmsKeyId: "arn:aws:kms:us-west-2:123456789012:key/abcd-1234-efgh-5678-ijkl-9012mnop",
});

// Export the S3 bucket name, IAM role ARN, IAM policy ARN, and export task status
export const bucketName = bucket.bucket;
export const roleArn = role.arn;
export const policyArn = policy.arn;
export const exportTaskStatus = exportTask.status;
