How Do I Configure a Gcp Pubsub Topic With Pulumi?

Configuring a GCP Pub/Sub Topic with Pulumi

In this guide, we will walk through the steps to configure a Google Cloud Pub/Sub topic using Pulumi. We will use TypeScript as our programming language, following the organizational preferences.

Step-by-Step Explanation

1. Install Pulumi and GCP Provider: Ensure you have Pulumi installed and the GCP provider set up. You can install the GCP provider using npm:

   npm install @pulumi/pulumi @pulumi/gcp
   

2. Create a New Pulumi Project: If you don’t have an existing Pulumi project, create a new one:

   pulumi new typescript
   

3. Configure GCP Credentials: Ensure your GCP credentials are configured. You can set the GOOGLE_CLOUD_KEYFILE_JSON environment variable to point to your service account key file:

   export GOOGLE_CLOUD_KEYFILE_JSON="/path/to/your/keyfile.json"
   

4. Define the Pub/Sub Topic: In your Pulumi program, define the Pub/Sub topic resource:

   import * as pulumi from "@pulumi/pulumi";
   import * as gcp from "@pulumi/gcp";
   
   // Create a new Pub/Sub topic
   const topic = new gcp.pubsub.Topic("my-topic", {
       name: "my-topic",
   });
   
   export const topicName = topic.name;
   

5. Deploy the Stack: Run pulumi up to deploy your changes:

   pulumi up
   

Summary

By following these steps, you can easily configure a GCP Pub/Sub topic using Pulumi. This involves installing the necessary packages, setting up your project and credentials, defining the Pub/Sub topic resource, and deploying your stack. Pulumi makes it straightforward to manage your cloud resources using code.

For more information, refer to the Pulumi GCP Provider documentation.

Full Code Example

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

// Create a new Pub/Sub topic
const topic = new gcp.pubsub.Topic("my-topic", {
    name: "my-topic",
});

export const topicName = topic.name;
