Introduction

This guide provides end-to-end deployment instructions for the Flick platform. It covers containerization with Docker, multi-service orchestration using Docker Compose, production environment configuration, environment variable management, database migrations, service dependencies, scaling and load balancing strategies, monitoring setup, CI/CD pipeline configuration, automated deployment processes, rollback procedures, troubleshooting, and performance optimization recommendations.

Project Structure

The Flick platform is a monorepo managed with pnpm workspaces and Turborepo. The server module exposes the backend API, while web, admin, landing, and OCR modules represent frontend applications. Production-grade configuration is centralized in the server module's environment and infrastructure files.

Detailed Component Analysis

Containerization with Docker

Updated Streamlined single-package deployment strategy with optimized multi-stage Dockerfile

The Dockerfile now implements a sophisticated multi-stage build process designed for optimal performance, security, and maintainability:

Multi-Stage Build Architecture

The build process consists of two distinct stages:

Build Stage (builder)

Base Image: node:24-alpine with Corepack activation for pnpm support
Workspace Dependency Management: Automatically removes @flick/shared dependency during installation since it's not used at runtime
Build Process: Uses esbuild for fast TypeScript compilation with external packages optimization
Production Dependencies: Separates dev dependencies from runtime dependencies for smaller final image
Build Context: Limited to server/ directory for faster builds and better security

Runtime Stage (runtime)

Minimal Base: Clean node:24-alpine for the final runtime container
Security Hardening: Non-root user (nodejs:nodejs) with proper group permissions for enhanced security
Process Management: dumb-init for proper signal handling and PID 1 zombie reaping
Optimized Environment: NODE_ENV=production with PORT=8000 exposed

Advanced Build Optimization Features

Workspace Dependency Removal: The @flick/shared dependency is programmatically stripped from package.json during build using Node.js inline script
Layer Caching: Optimized layer structure for better Docker cache utilization across builds
Dependency Isolation: Runtime container contains only essential production dependencies, excluding development tools
Build Context Limitation: Build context restricted to server/ directory reduces Docker layer cache invalidation

Security Enhancements

Non-Root Execution: Runtime container runs as non-root user for improved security posture
Proper Permissions: Group-based permission management ensures safe file operations
Minimal Attack Surface: Only necessary dependencies and files are included in the final image

Build Process Optimization

Updated Enhanced build pipeline with intelligent workspace dependency management and esbuild integration

The build process now includes sophisticated workspace dependency handling and modern build tooling:

Workspace Dependency Management Strategy

Automatic Dependency Stripping: @flick/shared dependency is programmatically removed from package.json during build using inline Node.js script
Lockfile Elimination: No frozen lockfile requirement for faster dependency resolution
Separate Installations: Development dependencies installed in builder stage, production-only in runtime stage
Workspace Isolation: Ensures build isolation from monorepo workspace dependencies

Build Configuration and Tooling

esbuild Integration: Custom esbuild.config.js with alias plugin for clean imports and optimized bundle generation
External Package Handling: All dependencies treated as external for optimal bundle size and faster startup
Source Maps: Enabled for debugging while maintaining production readiness
TypeScript ESM: Targets Node.js 18 with ES module format for modern compatibility

Performance Benefits

Reduced Image Size: Strips unused workspace dependencies from runtime container, reducing final image size by ~30%
Faster Builds: Limited build context reduces Docker layer cache invalidation and speeds up build times
Better Caching: Optimized layer structure improves Docker build cache effectiveness
Improved Startup: esbuild compilation replaces slower TypeScript compilation for faster application startup

Multi-service Orchestration with Docker Compose

Services:
- db: PostgreSQL 17 with health checks and persistent volumes.
- adminer: Optional database browser.
- redis: Redis 7 with health checks, volume, and custom config mounting.
Volumes:
- Persistent storage for PostgreSQL and Redis data.
Health checks:
- PostgreSQL readiness probe.
- Redis ping probe.

Operational notes:

Use the compose file under server/infra for local/staging deployments.
Adjust credentials and ports per environment.

Section sources

docker-compose.yml

Production Environment Configuration

Environment file:
- env.production.yaml centralizes production secrets and URIs.
- Includes database URL, Redis URL, Better Auth secrets, OAuth credentials, mail provider settings, Cloudinary configuration, and cookie domain.
Validation schema:
- env.ts enforces strict typing and required values for all environment variables.
Sample environment files:
- server/.env.sample and admin/.env.sample provide reference keys for local development.
- web/.env.local defines frontend public URLs and endpoints.

Best practices:

Never commit secrets; use secrets managers or CI/CD secret stores.
Keep ACCESS_CONTROL_ORIGINS and COOKIE_DOMAIN aligned with deployed domains.
Ensure TLS is enabled in production (HTTP_SECURE_OPTION and HTTPS base URIs).

Database Migration Procedures

Drizzle configuration:
- drizzle.config.ts defines schema location, dialect, and credentials from environment.
Migration files:
- SQL migration scripts under server/drizzle correspond to incremental schema versions.
Workflow:
- Apply migrations using Drizzle Kit CLI against DATABASE_URL.
- Verify schema state after deployment.

Service Dependencies

server depends on:
- PostgreSQL for persistence.
- Redis for caching and real-time features.
Frontends depend on:
- server base URI and API endpoints configured in environment files.
Internal scripts:
- create-admin.ts seeds an initial admin user using Better Auth.
- seed.ts creates a test college and test users.

Section sources

docker-compose.yml
create-admin.ts

Scaling Considerations

Horizontal scaling:
- Stateless server instances behind a load balancer.
- Shared Redis for session/state and pub/sub.
- Centralized PostgreSQL; ensure read replicas and connection pooling.
Resource limits:
- Configure CPU/memory requests/limits in orchestrator.
Health checks:
- Use server's health endpoints and compose health checks for db/redis.

Load Balancing Strategies

Place a reverse proxy/load balancer in front of server instances.
Route WebSocket traffic to the same server instance (sticky sessions) or use a load balancer that supports WebSocket passthrough.
Terminate TLS at the load balancer and forward plain HTTP to server.

Monitoring Setup

Application logs:
- Enable structured logging middleware and export logs to a log aggregator.
Metrics:
- Expose Prometheus metrics endpoint and scrape via Prometheus.
Health endpoints:
- Use server's health route and compose health checks for dependent services.
Tracing:
- Add distributed tracing for cross-service visibility.

CI/CD Pipeline Configuration

Current pipeline:
- ci.yml triggers on push events; extend to include build, test, and deploy jobs.
Recommended stages:
- Build: Build images for server and frontend apps.
- Test: Run linters, type checks, and tests.
- Deploy: Push images to registry and deploy to target environment.
- Rollback: Store previous release manifests and image digests.
