Build and Deploy a Webserver to Cloud Run

References

This repo is created based on the following reference tutorials. The first creates a docker container for a nodejs Webserver and deploy it to Cloud Run manually in GCP. Second tutorial uses Github Actions to build and deploy a Go app into GCP. In our case, we will build and deploy a nodejs Webserver by Github Actions into GCP Cloud Run.

1) Deploy and run a container with Cloud Run on Node.js

2) Google Cloud Run with Github Actions

Google Cloud Console

Step 1 Create a new Project

Under Search products and resources

search Manage resources
Create project

Or Under Menu IAM>Manage Resources

create project : gitact (choose your own project ID)

Step 2: Set variable and enable essential services

Under Console terminal >

export PROJECT_ID=gitact (project ID as above)
export ACCOUNT_NAME=gitacc (choose your own account name)

gcloud services enable cloudbuild.googleapis.com run.googleapis.com containerregistry.googleapis.com

Step 3: Create account

gcloud iam service-accounts create $ACCOUNT_NAME \ --description="Cloud Run deploy account" \ --display-name="Cloud-Run-Deploy"

Step 4: Set security settings

gcloud projects add-iam-policy-binding $PROJECT_ID \ --member=serviceAccount:$ACCOUNT_NAME@$PROJECT_ID.iam.gserviceaccount.com \ --role=roles/run.admin

gcloud projects add-iam-policy-binding $PROJECT_ID \ --member=serviceAccount:$ACCOUNT_NAME@$PROJECT_ID.iam.gserviceaccount.com \ --role=roles/storage.admin

gcloud projects add-iam-policy-binding $PROJECT_ID \ --member=serviceAccount:$ACCOUNT_NAME@$PROJECT_ID.iam.gserviceaccount.com \ --role=roles/iam.serviceAccountUser

Step 5: Create Credential (key.json)

gcloud iam service-accounts keys create key.json \ --iam-account $ACCOUNT_NAME@$PROJECT_ID.iam.gserviceaccount.com

Github

Step 1: Create a github repository

Step 2: Enter the Secrets in repository

Go to settings>secrets and enter to 4 secret values

GCP_APP_NAME=your app name (your choice of app name)
PROJECT_ID=gitact (your project name)
GCP_EMAIL = [email protected] (your client email from key.json)
GCP_CREDENTIALS = {key.json content}

Create the resources locally

Copy or clone the 4 files in this repository to your local folder:

  1. package.json
  2. index.js
  3. Dockerfile
  4. .github/workflows/GCP-Deploy.yml

Commit and Push

  1. Go to your local folder
  2. Git add, commit and push to Github repo

You should see github actions building and deploying the webserver container to your Google Cloud run

Verify

  1. Go to Google cloud platform.
  2. Under Cloud Run
  3. Click on the app name
  4. Click on the URL to verify webserver Hello World is running

Cleanup

To avoid incurring charges in GCP:

  1. delete the app under Cloud Run thereafter
  2. go to home>bucket resources and delete the buckets created for the app
