  2. Deploy the Debezium Connector on Kubernetes with TypeScript

How do I deploy the Debezium Connector on Kubernetes with TypeScript?

In this guide, we will deploy the Debezium Connector Docker image on a Kubernetes cluster using Pulumi with TypeScript. Debezium is an open-source distributed platform for change data capture. We will create a Kubernetes Deployment and Service to run the Debezium Connector.

Key Points:

  • We will use Pulumi to define our Kubernetes resources.
  • We will deploy the Debezium Connector Docker image.
  • We will create a Deployment and a Service to manage the Debezium Connector.
import * as pulumi from "@pulumi/pulumi";
import * as k8s from "@pulumi/kubernetes";

// Create a namespace for the Debezium Connector
const namespace = new k8s.core.v1.Namespace("debezium-namespace", {
    metadata: { name: "debezium" },
});

// Define the Debezium Connector Deployment
const appLabels = { app: "debezium-connector" };
const deployment = new k8s.apps.v1.Deployment("debezium-deployment", {
    metadata: {
        namespace: namespace.metadata.name,
    },
    spec: {
        selector: { matchLabels: appLabels },
        replicas: 1,
        template: {
            metadata: { labels: appLabels },
            spec: {
                containers: [{
                    name: "debezium-connector",
                    image: "debezium/connect:latest",
                    ports: [{ containerPort: 8083 }],
                    env: [
                        { name: "BOOTSTRAP_SERVERS", value: "kafka:9092" },
                        { name: "GROUP_ID", value: "debezium" },
                        { name: "CONFIG_STORAGE_TOPIC", value: "my-connect-configs" },
                        { name: "OFFSET_STORAGE_TOPIC", value: "my-connect-offsets" },
                        { name: "STATUS_STORAGE_TOPIC", value: "my-connect-statuses" },
                    ],
                }],
            },
        },
    },
});

// Define a Service to expose the Debezium Connector
const service = new k8s.core.v1.Service("debezium-service", {
    metadata: {
        namespace: namespace.metadata.name,
        labels: appLabels,
    },
    spec: {
        type: "ClusterIP",
        ports: [{ port: 8083, targetPort: 8083 }],
        selector: appLabels,
    },
});

// Export the URL for accessing the Debezium Connector service
export const debeziumServiceUrl = pulumi.interpolate`http://${service.metadata.name}.${namespace.metadata.name}.svc.cluster.local:8083`;

In this guide, we created a Kubernetes namespace for the Debezium Connector, defined a Deployment to manage the Debezium Connector container, and created a Service to expose the Debezium Connector within the cluster.

Key Points:

  • Created a namespace for organizing the Debezium resources.
  • Defined a Deployment to run the Debezium Connector Docker image.
  • Created a Service to expose the Debezium Connector for internal access.

By following these steps, we successfully deployed the Debezium Connector on a Kubernetes cluster using Pulumi and TypeScript.
