Using eks eu-kafka_mt-master with eu-reports-bigdata-staging

Question

Pulumi · Accepted Answer

To accomplish the goal of using Amazon EKS with Kafka in a specific cluster configuration, you need to deploy an EKS cluster and configure Kafka on it. For the Kafka part, you might typically use either Confluent Cloud Kafka or Amazon Managed Streaming for Apache Kafka (Amazon MSK). Since the requirement is specific and seems to hint at an existing cluster setup, I will provide you with guidance on how to create both resources using Pulumi, focusing on AWS since "eu-kafka_mt-master" implies an AWS region. However, it's important to note that direct integration like referring to a specific "eu-kafka_mt-master" would be part of custom configuration which might depend on existing infrastructure details not provided here.

To begin with, we need to create an EKS cluster. In this example, I'll show you how to create a basic EKS cluster using the `aws-native` package. I will then show you how to create a Kafka cluster using the `aws-native.msk.Cluster` resource. Note that we won't be able to directly interact with or refer to the "eu-kafka_mt-master" within Pulumi, as it seems to be a specific identifier that would need context beyond what Pulumi can infer.

### Creating an EKS Cluster

To create an EKS cluster, you will need to create an IAM role with the necessary permissions for EKS and pass its ARN to the cluster configuration. We'll simplify this part for the sake of the example. You will also define a VPC configuration that specifies the subnets and security groups for your worker nodes.

### Creating an MSK Cluster

For the MSK cluster, you will specify the required properties such as broker node group information, Kafka version, and other configuration details. Ensure you have created the necessary IAM roles and security groups with appropriate permissions and access rules for the MSK to function within your VPC.

Now, let's see the code on how you can achieve this within Pulumi:

```typescript
import * as eks from "@pulumi/aws-native/eks";
import * as msk from "@pulumi/aws-native/msk";
import * as ec2 from "@pulumi/aws-native/ec2";
import * as iam from "@pulumi/aws-native/iam";

// Create a new VPC for the EKS cluster
const vpc = new ec2.Vpc("vpc", {
    cidrBlock: "10.100.0.0/16" // Specify your CIDR block
});

// Create IAM role for EKS
const eksRole = new iam.Role("eksRole", {
    assumeRolePolicyDocument: {
        Version: "2012-10-17",
        Statement: [{
            Effect: "Allow",
            Principal: {
                Service: "eks.amazonaws.com"
            },
            Action: "sts:AssumeRole"
        }]
    }
});

// Create an EKS cluster
const cluster = new eks.Cluster("cluster", {
    name: "eu-eks-cluster", // Define your EKS cluster name
    roleArn: eksRole.arn,
    resourcesVpcConfig: {
        subnetIds: vpc.subnetIds
    },
    version: "1.21" // Specify the desired Kubernetes version
});

// Create an MSK cluster
const kafkaCluster = new msk.Cluster("kafkaCluster", {
    clusterName: "eu-reports-bigdata-staging", // Define your Kafka cluster name
    kafkaVersion: "2.8.1", // Specify the Kafka version you want to use
    numberOfBrokerNodes: 3, // Define the number of broker nodes
    brokerNodeGroupInfo: {
        instanceType: "kafka.m5.large", // Specify instance type for the brokers
        clientSubnets: vpc.publicSubnetIds, // Subnets for the MSK cluster
        ebsVolumeSize: 1000 // Define the size of EBS volumes attached to each broker node
        // You should also define security groups or use the default one
    }
    // You may need to specify additional configuration based on your requirements
});
```

Explanations:
- The `ec2.Vpc` resource creates a new VPC to host your EKS and MSK clusters; the CIDR block should be chosen based on your network planning.
- The `iam.Role` resource creates a new IAM role that EKS can assume to create and manage AWS resources on behalf of your Kubernetes workloads.
- The `eks.Cluster` resource creates a new EKS cluster with the specified Kubernetes version and VPC configuration.
- The `msk.Cluster` resource creates a new Amazon MSK cluster with a specified number of broker nodes and storage configuration.

Remember, the specific configuration details (like IAM roles, policies, security groups, etc.) would need to be customized based on your organization's security and compliance requirements. This code sets you on the path to creating EKS and MSK clusters, but fine-tuning them will require a deeper understanding of your specific needs and AWS configurations.
