DevOps with Google Antigravity: Docker, Kubernetes & CI/CD Pipeline Automation

Google Antigravity excels at DevOps tasks. From generating Dockerfiles to crafting Kubernetes manifests and CI/CD pipelines, Gemini 3 understands infrastructure deeply. This guide covers practical DevOps workflows.

Docker with Antigravity

Generating Optimized Dockerfiles

You: "Create a production Dockerfile for this Next.js application"

Gemini 3 generates:

# Build stage
FROM node:20-alpine AS builder

WORKDIR /app

# Install dependencies first (better caching)
COPY package*.json ./
RUN npm ci --only=production=false

# Copy source and build
COPY . .
RUN npm run build

# Production stage
FROM node:20-alpine AS runner

WORKDIR /app

ENV NODE_ENV=production
ENV NEXT_TELEMETRY_DISABLED=1

# Create non-root user for security
RUN addgroup --system --gid 1001 nodejs
RUN adduser --system --uid 1001 nextjs

# Copy only necessary files
COPY --from=builder /app/public ./public
COPY --from=builder /app/.next/standalone ./
COPY --from=builder /app/.next/static ./.next/static

USER nextjs

EXPOSE 3000

ENV PORT=3000
ENV HOSTNAME="0.0.0.0"

CMD ["node", "server.js"]

Docker Compose for Development

You: "Create docker-compose for local development with PostgreSQL and Redis"

# docker-compose.yml
version: "3.8"

services:
  app:
    build:
      context: .
      dockerfile: Dockerfile.dev
    ports:
      - "3000:3000"
    volumes:
      - .:/app
      - /app/node_modules
    environment:
      - DATABASE_URL=postgresql://postgres:postgres@db:5432/myapp
      - REDIS_URL=redis://redis:6379
    depends_on:
      db:
        condition: service_healthy
      redis:
        condition: service_started

  db:
    image: postgres:16-alpine
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DB: myapp
    volumes:
      - postgres_data:/var/lib/postgresql/data
      - ./init.sql:/docker-entrypoint-initdb.d/init.sql
    ports:
      - "5432:5432"
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U postgres"]
      interval: 5s
      timeout: 5s
      retries: 5

  redis:
    image: redis:7-alpine
    ports:
      - "6379:6379"
    volumes:
      - redis_data:/data

  # Optional: Database admin UI
  adminer:
    image: adminer
    ports:
      - "8080:8080"
    depends_on:
      - db

volumes:
  postgres_data:
  redis_data:
