Creating a Google Function with Gitlab integration in 10 minutes!

Hello everyone!

I’m working in a side project and I needed to create a Google Functions for my back-end, using NodeJS, Google Cloud SQL with MySQL.

I will show you the easier way to create an integration between your Gitlab and Google Cloud Platform.

You can see my NodeJS Project example in my Github
https://github.com/massatotakaki/first-gcp-function-integration

1. Let’s start creating an initial NodeJS project based on GoogleCloud Docs instructions.
   https://cloud.google.com/functions/docs/first-nodejs
   or clone my Github example project
2. Let’s create a new project on Google Cloud Platform.

new project screen

Create a Service Account

Click on CREATE SERVICE ACCOUNT

Write your service account name

Grant the Roles:
-Cloud Functions Admin
-Service Account User

Click on CREATE KEY

Create a JSON file, download and save to the project root

After creation you can see your Keys.

Now your project looks like this

3. Let’s create a integration

At the root of the project, create a file named: .gitlab-ci.yml

deploy to gcloud:
image: google/cloud-sdk:latest
script:
- gcloud auth activate-service-account — key-file=./gcloud-service-key.json
- gcloud config set project PROJECT-GCP-NAME
- gcloud functions deploy FUNCTION-NAME — runtime nodejs8 — trigger-http — allow-unauthenticated
