Hello Node.js Service

Description

A simple Fastify server intended to serve as an example of deploying a Node.js application to Google Cloud Run.

Usage

After cloning the repository, install the dependencies:

$ npm install

To start the server, run:

$ npm start

Locally, this will run the server on http://localhost:8080.

To run inside a Docker container, download the pack CLI and then run:

$ pack build app --builder gcr.io/buildpacks/builder
$ docker run -it --init -p 8080:8080 -e PORT=8080 app

Notes

1. The server reads from the PORT environment variable to determine which port to listen on. This is important because Google Cloud Run defines this variable and it's the only port that will be open.
2. Google Cloud Run also requires that the server listen on 0.0.0.0 because 127.0.0.1 is a loopback address with no external access.
3. You no longer need to define a Dockerfile to run Node.js projects on Google Cloud Run. You can instead use the built-in Node.js Buildpack. All you need to do is define npm start.
