Using Aws Msk With Codecommit

Introduction

In this guide, we will walk through setting up AWS Managed Streaming for Apache Kafka (MSK) and integrating it with AWS CodeCommit using Pulumi. AWS MSK is a fully managed service that makes it easy to build and run applications that use Apache Kafka to process streaming data. AWS CodeCommit is a fully managed source control service that makes it easy for teams to host secure and scalable Git repositories.

Step-by-Step Explanation

Step 1: Setting Up AWS MSK

1. Create a VPC: AWS MSK requires a VPC for network isolation.
2. Create Subnets: Create subnets in the VPC for the MSK cluster.
3. Create Security Groups: Define security groups to control access to the MSK cluster.
4. Create MSK Cluster: Use Pulumi to create the MSK cluster with the specified configuration.

Step 2: Setting Up AWS CodeCommit

1. Create CodeCommit Repository: Use Pulumi to create a new CodeCommit repository.
2. Configure Repository: Set up the repository with necessary permissions and settings.

Step 3: Integrating MSK with CodeCommit

1. Create IAM Roles and Policies: Create IAM roles and policies to allow MSK to interact with CodeCommit.
2. Configure MSK Cluster: Update the MSK cluster configuration to use the IAM roles for accessing CodeCommit.

Summary

In this guide, we have successfully set up an AWS MSK cluster and integrated it with AWS CodeCommit using Pulumi. This setup allows you to leverage the power of Apache Kafka for streaming data processing while using CodeCommit for source control. By following these steps, you can ensure a secure and scalable environment for your applications.

Full Code Example

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

// Create a VPC
const vpc = new aws.ec2.Vpc("mskVpc", {
    cidrBlock: "10.0.0.0/16",
});

// Create Subnets
const subnet1 = new aws.ec2.Subnet("mskSubnet1", {
    vpcId: vpc.id,
    cidrBlock: "10.0.1.0/24",
    availabilityZone: "us-west-2a",
});

const subnet2 = new aws.ec2.Subnet("mskSubnet2", {
    vpcId: vpc.id,
    cidrBlock: "10.0.2.0/24",
    availabilityZone: "us-west-2b",
});

// Create Security Group
const securityGroup = new aws.ec2.SecurityGroup("mskSecurityGroup", {
    vpcId: vpc.id,
    ingress: [{
        protocol: "tcp",
        fromPort: 9092,
        toPort: 9092,
        cidrBlocks: ["0.0.0.0/0"],
    }],
    egress: [{
        protocol: "-1",
        fromPort: 0,
        toPort: 0,
        cidrBlocks: ["0.0.0.0/0"],
    }],
});

// Create MSK Cluster
const mskCluster = new aws.msk.Cluster("mskCluster", {
    clusterName: "my-msk-cluster",
    kafkaVersion: "2.6.0",
    numberOfBrokerNodes: 2,
    brokerNodeGroupInfo: {
        instanceType: "kafka.m5.large",
        clientSubnets: [subnet1.id, subnet2.id],
        securityGroups: [securityGroup.id],
    },
});

// Create CodeCommit Repository
const codeCommitRepo = new aws.codecommit.Repository("myRepo", {
    repositoryName: "my-codecommit-repo",
});

// Create IAM Role for MSK to access CodeCommit
const mskRole = new aws.iam.Role("mskRole", {
    assumeRolePolicy: JSON.stringify({
        Version: "2012-10-17",
        Statement: [{
            Action: "sts:AssumeRole",
            Principal: {
                Service: "msk.amazonaws.com",
            },
            Effect: "Allow",
            Sid: "",
        }],
    }),
});

// Attach Policy to IAM Role
const mskPolicy = new aws.iam.Policy("mskPolicy", {
    policy: JSON.stringify({
        Version: "2012-10-17",
        Statement: [{
            Action: [
                "codecommit:GitPull",
                "codecommit:GitPush",
            ],
            Resource: codeCommitRepo.arn,
            Effect: "Allow",
        }],
    }),
});

const rolePolicyAttachment = new aws.iam.RolePolicyAttachment("mskRolePolicyAttachment", {
    role: mskRole.name,
    policyArn: mskPolicy.arn,
});

// Export outputs
export const vpcId = vpc.id;
export const subnetIds = [subnet1.id, subnet2.id];
export const securityGroupId = securityGroup.id;
export const mskClusterArn = mskCluster.arn;
export const codeCommitRepoArn = codeCommitRepo.arn;
