Script Deploy NodeJS App in Google Cloud App Engine & Cloud Run

Step before deploy app engine and cloud run

1. Create Project
2. Enable Cloud Build API (Click Here to Enable Cloud Build API)

App Engine

1. Enable App Engine API Click Here
2. Clone your repo in google cloud shell
3. Prepare database
4. Create app.yaml file and fill the file with this code

   runtime: nodejs20
   

5. Make sure your package.json script is this

   "scripts": {  
   	"start": "node server.js"
   }
   

6. Run this command to deploy to App Engine

   gcloud app deploy
   

7. Test your app

Cloud Run

1. Clone your repo in google cloud shell
2. Prepare database
3. Create artifact registry repo
4. Create Dockerfile file and fill the with this code

   #Use the official Node.js 14 image as the base image
   FROM node:20
   
   #Set the working directory in the container
   WORKDIR /usr/src/app
   
   #Copy package.json and package-lock.json to the working directory
   COPY package*.json ./
   
   #Install app dependencies
   RUN npm install

   CMD ["npm", "start"]
   

5. Build docker image and don't forget to tag it

   docker build -t <image-name>:<tag> .
   

6. Create tag to Artifact Registry

   docker tag <image_name>:<tag> <location>-docker.pkg.dev/<project_id>/<repository_name>/<image_name>:<tag>
   

7. Push docker image to artifact registry

   docker push <location>-docker.pkg.dev/<project_id>/<repository_name>/<image_name>:<tag>
   

8. Deploy cloud run by pull docker image from artifact registry

   gcloud run deploy <service-name> --image <image-uri>
   

9. Test your app
