Deploy NextJS on GCP

Create Docker Image

# Install dependencies only when needed
FROM node:alpine
ENV NODE_ENV production
WORKDIR /app
COPY . .
RUN npm install && npm run build
EXPOSE 3000
CMD ["npm", "start"]

#.dockerignore
node_modules
.next
npm-debug.log
.husky
.github

Setup GCP environment

• Start New Project and push docker image to gcp container registry

gcloud auth login
gcloud auth configure-docker
docker push asia.gcr.io/${PROJECT_ID}/${IMAGE_NAME}

• Create New Service for run the docker image

Setup Pipeline

• Set pipeline by using github action

# This is a basic workflow to help you get started with Actions
name: My Website CI

# Controls when the action will run. 
on:
  # Triggers the workflow on push or pull request events but only for the main branch
  push:
    branches: [ main ]

# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
  # This workflow contains a single job called "build"
  build:
    # The type of runner that the job will run on
    runs-on: ubuntu-latest
    env:
      IMAGE_NAME: asia.gcr.io/${{ secrets.GCP_PROJECT_ID }}/my-website
    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:
      # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
      - name: Checkout
        uses: actions/checkout@v2     
             
      # Install NodeJS
      - name: Setup Node.js environment
        uses: actions/setup-node@v2.1.5
        
      # Install node_modules
      - name: Install Node_modules
        run: npm install

      # Fix Style
      - name: Fix Style
        run: npm run lint && npm run lint:style
        
      # GCP Login
      - name: GCP Login
        uses: GoogleCloudPlatform/github-actions/setup-gcloud@master
        with:
          project_id: ${{ secrets.GCP_PROJECT_ID }}
          service_account_email: ${{ secrets.GCP_EMAIL }}
          service_account_key: ${{ secrets.GCP_CREDENTIALS }}
          
      - name: GCP Configure Docker
        run: gcloud auth configure-docker --quiet
      
      # Build Docker Image
      - name: Build Docker image
        run: docker build . -t $IMAGE_NAME
        
      # Push Docker Image   
      - name: Push Docker image
        run: docker push $IMAGE_NAME  
      
      # Deploy to Cloud Run
      - name: Deploy to Cloud Run
        run: gcloud run deploy my-website --image $IMAGE_NAME --region asia-east1  --platform managed
