GCP App Engine Standard Environment Deployment With Pulumi

In this solution, we will deploy a web application to Google Cloud Platform (GCP) using the App Engine standard environment with TypeScript using Pulumi. The key services involved in this deployment are Google App Engine, Google Cloud Storage, and Google Cloud IAM. We will create a new App Engine application, deploy a sample application, and configure the necessary IAM roles and permissions.

Introduction

In this solution, we will deploy a web application to Google Cloud Platform (GCP) using the App Engine standard environment with TypeScript using Pulumi. The key services involved in this deployment are Google App Engine, Google Cloud Storage, and Google Cloud IAM. We will create a new App Engine application, deploy a sample application, and configure the necessary IAM roles and permissions.

Step-by-Step Explanation

Step 1: Set up Pulumi and GCP Provider

1. Initialize a new Pulumi project.
2. Configure the GCP provider with the necessary credentials.

Step 2: Create a Google Cloud Storage Bucket

1. Define a new Google Cloud Storage bucket resource.
2. Configure the bucket with the necessary properties.

Step 3: Create a Google App Engine Application

1. Define a new App Engine application resource.
2. Configure the application with the necessary properties.

Step 4: Deploy a Sample Application

1. Define the source code for the sample application.
2. Configure the deployment settings for the application.

Step 5: Configure IAM Roles and Permissions

1. Define the necessary IAM roles and permissions for the application.
2. Assign the roles to the appropriate service accounts.

Key Points

• Pulumi allows for infrastructure as code using familiar programming languages.
• Google App Engine provides a fully managed platform for building and deploying applications.
• Google Cloud Storage is used for storing static assets and other data.
• IAM roles and permissions are crucial for securing access to resources.

Conclusion

In this solution, we successfully deployed a web application to GCP using the App Engine standard environment with TypeScript using Pulumi. We utilized key GCP services such as App Engine, Cloud Storage, and IAM to achieve this deployment. Pulumi’s infrastructure as code approach made it easy to define and manage our resources using TypeScript.

Full Code Example

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

// Create a Google Cloud Storage bucket
const bucket = new gcp.storage.Bucket("my-bucket", {
    location: "US",
});

// Create a Google App Engine application
const app = new gcp.appengine.Application("my-app", {
    locationId: "us-central",
});

// Deploy a new version of the App Engine application
const appVersion = new gcp.appengine.StandardAppVersion("my-app-version", {
    service: "default",
    runtime: "nodejs14",
    entrypoint: {
        shell: "node app.js"
    },
    deployment: {
        zip: {
            sourceUrl: pulumi.interpolate`gs://${bucket.name}/app.zip`,
        },
    },
    automaticScaling: {
        maxIdleInstances: 1,
        minIdleInstances: 0,
    },
});

// Create a custom IAM role
const customRole = new gcp.projects.IAMCustomRole("my-custom-role", {
    roleId: "myCustomRole",
    title: "My Custom Role",
    description: "A custom role for my application.",
    permissions: [
        "appengine.applications.get",
        "appengine.services.get",
        "appengine.versions.get",
        "storage.buckets.get",
        "storage.objects.get",
    ],
    stage: "GA",
});

// Assign the custom IAM role to the App Engine default service account
const iamBinding = new gcp.projects.IAMBinding("my-iam-binding", {
    members: [pulumi.interpolate`serviceAccount:${app.project}.appspot.gserviceaccount.com`],
    role: customRole.name,
    project: app.project,
});

export const bucketName = bucket.name;
export const appEngineUrl = pulumi.interpolate`https://${app.project}.appspot.com`;
