Google Cloud Serverless Application

The Google Cloud Serverless Application template scaffolds a Pulumi project that deploys a Google Cloud Storage bucket configured for static website hosting and a Cloud Functions Gen 2 function for the application backend. The template ships with placeholder web and function content so the project deploys end to end out of the box.

Before you deploy

Cloud Functions Gen 2 functions are gated at the underlying Cloud Run service, so the public-invoker grant in this template is created with gcp.cloudrun.IamMember (roles/run.invoker). The identity running pulumi up needs to be able to set IAM policy on Cloud Run — typically roles/run.admin, or a custom role that includes run.services.setIamPolicy — in addition to the permissions needed to create the function and storage resources.

Using this template

To use this template to deploy your own serverless application, make sure you’ve installed Pulumi and configured your Google Cloud credentials, then create a new project using the template in the language of your choice:

$ mkdir my-serverless-app && cd my-serverless-app
$ pulumi new serverless-gcp-typescript

Alternatively, you can create and configure a new project with this template (serverless-gcp-typescript) in Pulumi Cloud.

$ mkdir my-serverless-app && cd my-serverless-app
$ pulumi new serverless-gcp-python

Alternatively, you can create and configure a new project with this template (serverless-gcp-python) in Pulumi Cloud.

$ mkdir my-serverless-app && cd my-serverless-app
$ pulumi new serverless-gcp-go

Alternatively, you can create and configure a new project with this template (serverless-gcp-go) in Pulumi Cloud.

$ mkdir my-serverless-app && cd my-serverless-app
$ pulumi new serverless-gcp-csharp

Alternatively, you can create and configure a new project with this template (serverless-gcp-csharp) in Pulumi Cloud.

$ mkdir my-serverless-app && cd my-serverless-app
$ pulumi new serverless-gcp-yaml

Alternatively, you can create and configure a new project with this template (serverless-gcp-yaml) in Pulumi Cloud.

Follow the prompts to complete the new-project wizard. When it’s done, you’ll have a complete Pulumi project that’s ready to deploy and configured with the most common settings. Feel free to inspect the code in index.js index.ts __main__.py main.go Program.cs Program.fs Program.vb App.java Pulumi.yaml for a closer look.

Deploying the project

The template requires no additional configuration. Once the new project is created, you can deploy it immediately with pulumi up:

$ pulumi up

When the deployment completes, Pulumi exports the following stack output values:

siteURL

The HTTP URL of the static website.

apiURL

The HTTP URL of the serverless function endpoint.

Output values like these are useful in many ways, most commonly as inputs for other stacks or related cloud resources. The computed siteURL, for example, can be used from the command line to open the newly deployed website in your favorite web browser:

$ open $(pulumi stack output siteURL)

Customizing the project

Projects created with the serverless template expose the following configuration settings:

sitePath

The path to the folder containing the files of the website. Defaults to www, which is the name (and relative path) of the folder included with the template.

appPath

The path to the folder containing the serverless functions to be deployed. Defaults to app, which is also included with the template.

indexDocument

The file to use for top-level pages. Defaults to index.html.

errorDocument

The file to use for error pages. Defaults to error.html.

All of these settings are optional and may be adjusted either by editing the stack configuration file directly (by default, Pulumi.dev.yaml) or by changing their values with pulumi config set:

$ pulumi config set sitePath ../my-existing-website/build
$ pulumi up

Cleaning up

You can cleanly destroy the stack and all of its infrastructure with pulumi destroy:

$ pulumi destroy
