Workflow Phases

Phase 1: Container Strategy & Architecture (15-20 minutes)

🏗️ Containerization Architecture Design

Container Strategy Assessment:
  Application Analysis:
    - Monolithic vs microservices architecture
    - Service dependencies and communication patterns
    - Data persistence and state management requirements
    - Resource utilization and scaling patterns
  
  Container Design Patterns:
    - Single-container applications
    - Multi-container applications with Docker Compose
    - Microservices with service mesh integration
    - Sidecar patterns for logging, monitoring, security

📊 Resource Planning & Optimization

• Base Image Selection: Alpine, Ubuntu, Distroless, or custom base images

• Multi-Stage Build Strategy: Separate build and runtime environments

• Layer Optimization: Minimize image size and build time

• Security Considerations: Vulnerability scanning, minimal attack surface

🎯 Container Orchestration Strategy

Orchestration Options:
  Docker Compose:
    - Development and testing environments
    - Simple multi-container applications
    - Local development workflows
    - CI/CD pipeline integration
  
  Kubernetes:
    - Production-grade orchestration
    - Auto-scaling and load balancing

COPY package*.json ./
RUN npm ci --only=production && npm cache clean --force
COPY . .
RUN npm run build

# Runtime Stage
FROM node:18-alpine AS runtime
RUN addgroup -g 1001 -S nodejs && adduser -S nextjs -u 1001
WORKDIR /app
COPY --from=builder --chown=nextjs:nodejs /app/dist ./dist
COPY --from=builder --chown=nextjs:nodejs /app/node_modules ./node_modules
COPY --from=builder --chown=nextjs:nodejs /app/package.json ./package.json

USER nextjs
EXPOSE 3000
HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
  CMD curl -f http://localhost:3000/health || exit 1
