Google Cloud Serverless Application

The Serverless Application template creates an infrastructure as code project in your favorite language that deploys a serverless application to Google Cloud Platform with Pulumi. It deploys a Google Cloud Storage bucket configured for static website hosting and another bucket to host the source code for a Cloud Function written in the same language as the template. The template ships with placeholder content to give you a working project out of the box that you can customize easily and extend to suit your needs.

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 your language of choice:

$ mkdir my-serverless-app && cd my-serverless-app
$ pulumi new serverless-gcp-typescript
$ mkdir my-serverless-app && cd my-serverless-app
$ pulumi new serverless-gcp-python
$ mkdir my-serverless-app && cd my-serverless-app
$ pulumi new serverless-gcp-go
$ mkdir my-serverless-app && cd my-serverless-app
$ pulumi new serverless-gcp-csharp
$ mkdir my-serverless-app && cd my-serverless-app
$ pulumi new serverless-gcp-yaml

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 as shown below.

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

Tidying up

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

$ pulumi destroy
