GCP Cloud Build Triggers With Pulumi

Introduction

In this guide, we will walk through setting up GCP Cloud Build triggers using Pulumi. This setup will allow you to automate your build and deployment processes on Google Cloud Platform (GCP) using Pulumi’s infrastructure as code capabilities. The key services involved include Google Cloud Build and Pulumi.

Step-by-Step Explanation

Step 1: Install Pulumi and GCP CLI

First, ensure that you have Pulumi and the GCP CLI installed on your machine. You can install Pulumi by following the instructions here. For the GCP CLI, follow the instructions here.

Step 2: Set Up Pulumi Project

Create a new Pulumi project if you don’t already have one. You can do this by running:

pulumi new typescript

Follow the prompts to set up your project.

Step 3: Configure GCP Authentication

Authenticate your GCP CLI with your Google Cloud account:

gcloud auth login
gcloud config set project <YOUR_PROJECT_ID>

Step 4: Define Cloud Build Trigger in Pulumi

In your Pulumi program, define a Cloud Build trigger. Here’s an example TypeScript code snippet to get you started:

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

const trigger = new gcp.cloudbuild.Trigger("trigger", {
    description: "My Cloud Build Trigger",
    triggerTemplate: {
        projectId: "<YOUR_PROJECT_ID>",
        repoName: "<YOUR_REPO_NAME>",
        branchName: "^main$",
    },
    filename: "cloudbuild.yaml",
});

Replace <YOUR_PROJECT_ID> and <YOUR_REPO_NAME> with your actual project ID and repository name.

Step 5: Create a cloudbuild.yaml File

Create a cloudbuild.yaml file in your repository. This file defines the build steps. Here’s an example:

steps:
- name: "gcr.io/cloud-builders/gcloud"
  args: ["builds", "submit", "--tag=gcr.io/$PROJECT_ID/my-app"]

Step 6: Deploy the Pulumi Stack

Run the following commands to deploy your Pulumi stack:

pulumi stack init <STACK_NAME>
pulumi up

Follow the prompts to complete the deployment.

Summary

In this guide, we set up a GCP Cloud Build trigger using Pulumi. We walked through installing necessary tools, configuring authentication, defining the Cloud Build trigger in Pulumi, creating a cloudbuild.yaml file, and deploying the Pulumi stack. This setup helps automate your build and deployment processes on GCP using Pulumi.

Full Code Example

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

const trigger = new gcp.cloudbuild.Trigger("trigger", {
    description: "My Cloud Build Trigger",
    triggerTemplate: {
        projectId: "<YOUR_PROJECT_ID>",
        repoName: "<YOUR_REPO_NAME>",
        branchName: "^main$",
    },
    filename: "cloudbuild.yaml",
});
