Deploying Google Cloud Functions in 5 easy steps

Recently I did a project which involved deploying Google Cloud Functions to do the stuff.

This is how to start using GCF the easy way.

First, you need a project to be created already. If not, go to https://console.cloud.google.com and create it. You also need to visit Google Cloud Functions section at least once to make sure GCF API is enabled. You’ll also need to create a storage bucket for a function — there’s no rocket science there, just pick up random name 👍

Second, you need to have Google Cloud SDK installed on your machine. You can download it from here or just go with brew:

brew install google-cloud-sdk

Third, you need to set the current project for Google Cloud SDK. The directory structure doesn’t need to be there yet.

gcloud auth login
gcloud config set project <project_name>

Forth step! We need a nodejs project set up. It’s enough to just do yarn init in a desired project and create index.js with a content of your new cloud function, like this:

exports.fetch = function(req, res) { res.send('Hello, world!'); }

Final step 🎉

gcloud beta functions deploy <your_function_name> --entry-point=<your_entry_point_name_exported_by_index.js> --trigger-http --stage-bucket=<your_stage_bucket>

Example:

gcloud beta functions deploy react-server-side-rendering-service --entry-point=render --trigger-http --stage-bucket=my-awesome-startup-gcf-bucket

That’s it! 😎
