docker-apps

A setup guide for Turborepo, a tool that coordinates JavaScript projects stored in one shared codebase, called a monorepo.

In plain words
What is it for?
Use it when maintaining the listed auth, order, product, web, and shared-package workspaces, or when configuring their build pipelines.
Why use it?
It gives shared rules for building, caching, and working across several apps and packages without managing each project separately.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add rules/proyecto26/projectx/docker-apps
Clone the repo
git clone --depth 1 https://github.com/proyecto26/projectx

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 1,347 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 1 finding. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

docker-apps scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Docker Application Services

Service Overview

Application Services

  • auth (NestJS - Port 8081, Debug 9229)
  • order (NestJS - Port 8082, Debug 9230)
  • product (NestJS - Port 8083, Debug 9231)
  • web (React Router SSR - Port 3000) - Optional

Common Service Template

Shared Configuration

x-service-common: &service-common
  networks:
    - projectx-network
  restart: unless-stopped
  volumes:
    - .:/app
    - /app/node_modules

All services inherit from this base configuration to ensure consistency.

NestJS Service Pattern

Standard NestJS Service

service-name:
  <<: *service-common
  build:
    context: .
    dockerfile: Dockerfile
    target: development
  command: >
    sh -c "pnpm install --frozen-lockfile &&
           pnpm turbo run build --filter=service-name^... &&
           pnpm --filter @projectx/db run prisma:generate &&
           pnpm --filter @projectx/db run prisma:migrate &&
           cd /app/apps/service-name &&
           pnpm start:dev"
  environment:
    - NODE_ENV=development
    - WATCHPACK_POLLING=true
    - CHOKIDAR_USEPOLLING=true
    - CHOKIDAR_INTERVAL=500
  ports:
    - "PORT:PORT"
    - "DEBUG_PORT:DEBUG_PORT"
  depends_on:
    db:
      condition: service_healthy
    temporal:
      condition: service_healthy

Build Process for Apps

  1. Install dependencies with pnpm install --frozen-lockfile
  2. Build package dependencies with Turborepo filter
  3. Generate Prisma client
  4. Run Prisma migrations
  5. Start service in watch mode

Environment Variables for Apps

Common Variables

environment:
  - NODE_ENV=development
  - DATABASE_URL=postgresql://${POSTGRES_USER}:${POSTGRES_PASSWORD}@db:${POSTGRES_PORT}/${POSTGRES_DB}
  - TEMPORAL_HOST=temporal:7233
  - TEMPORAL_NAMESPACE=${TEMPORAL_NAMESPACE:-default}

File Watching (Hot Reload)

environment:
  - WATCHPACK_POLLING=true
  - CHOKIDAR_USEPOLLING=true
  - CHOKIDAR_INTERVAL=500

These enable hot reload in Docker containers.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

docker-apps is a cursor rule published in the GitHub repository proyecto26/projectx (83 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,347 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
