How do I install the Deployment skill?

Run npx skillmds@latest add n43-studio/deployment in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Deployment safe to use?

This skill has not completed SkillMD's automated safety review yet. Capability flags: docs only. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Deployment?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Deployment free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

Deployment Best Practices

Quick Start

Docker Build Pattern

Both frontend and backend use multi-stage builds:

Builder stage: Install dependencies, compile TypeScript/build assets
Production stage: Copy only built artifacts, install prod dependencies, run as non-root user

Environment Configuration

Follow 12-Factor App principles:

All config via environment variables
PORT, NODE_ENV, CORS_ORIGINS, DATABASE_URL
Frontend uses VITE_ prefix for client-side vars
Never commit .env files

Health Checks

Every backend must expose:

GET /api/health — basic liveness check
GET /api/health/ready — readiness with dependency checks

Docker Compose

# Build and run
docker-compose -f docker/docker-compose.yml up --build

# Run in background
docker-compose -f docker/docker-compose.yml up -d

# View logs
docker-compose -f docker/docker-compose.yml logs -f

Google Cloud Run

gcloud builds submit --tag gcr.io/PROJECT_ID/backend
gcloud run deploy backend \
  --image gcr.io/PROJECT_ID/backend \
  --platform managed \
  --region us-central1

Security Essentials

Run containers as non-root user
Use helmet() for security headers
Configure CORS with explicit origin whitelist
Use specific Node.js image versions

Port Reference

Service	Default Port
Vite dev server	5173
Express/Node	3001
Nginx HTTP	80
PostgreSQL	5432
