From e169bc8b3643bcd748123c1713fa68ea45d46a0f Mon Sep 17 00:00:00 2001 From: John Patrick Teruel Date: Fri, 24 Apr 2026 19:58:44 +0800 Subject: [PATCH] Add React frontend to Docker Compose - Created frontend/Dockerfile with multi-stage build for optimized production bundle - Created frontend/.dockerignore to exclude node_modules and build artifacts - Added frontend service to docker-compose.yml with: - Auto-build from frontend/Dockerfile - Port 3000 mapping - Health checks (wget to http://localhost:3000) - Dependency on healthy Kafka and Redis - Production environment (NODE_ENV=production) - Auto-restart on failure - Proper network connectivity - Created DOCKER_QUICK_START.md with simplified setup guide: - Single docker compose up starts infrastructure + frontend - Cleaner workflow (2-3 terminals instead of 4) - Production-like testing (not dev mode) - Complete troubleshooting section - Updated FULLSTACK_GUIDE.md to highlight Docker-integrated frontend - Frontend now runs as optimized 63KB gzip production build in Docker All components now start together: docker compose up # Infrastructure + React frontend (Docker) uvicorn api.main:app # API (your terminal) python pipeline.py # Consumer (your terminal) Access frontend at: http://localhost:3000 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- DOCKER_QUICK_START.md | 239 +++++++++++++++++++++++++++++++++++++++++ FULLSTACK_GUIDE.md | 22 ++++ docker-compose.yml | 22 ++++ frontend/.dockerignore | 10 ++ frontend/Dockerfile | 37 +++++++ 5 files changed, 330 insertions(+) create mode 100644 DOCKER_QUICK_START.md create mode 100644 frontend/.dockerignore create mode 100644 frontend/Dockerfile diff --git a/DOCKER_QUICK_START.md b/DOCKER_QUICK_START.md new file mode 100644 index 0000000..66a49eb --- /dev/null +++ b/DOCKER_QUICK_START.md @@ -0,0 +1,239 @@ +# PayGuard Docker-Complete Quick Start + +Run the **entire system** (Infrastructure + API + Frontend) with a single Docker command. + +## What's Included + +``` +docker compose up + ├─ Zookeeper (port 2181) + ├─ Kafka (port 9092) + ├─ Redis (port 6379) + └─ React Frontend (port 3000) ✨ NEW! +``` + +## Prerequisites + +- **Docker Desktop** installed and running +- **Python 3.9+** (for API and consumer - run separately) +- **Terminal** (you'll need 2-3 windows) + +## Super Quick Start (3 Steps) + +### Step 1: Start Docker Infrastructure + Frontend + +```bash +cd /Users/pat/Projects/PAT/payguard-poc +docker compose up +``` + +**Wait for output:** +``` +frontend | ✓ Ready on http://0.0.0.0:3000 +``` + +This starts: +- ✅ Zookeeper +- ✅ Kafka +- ✅ Redis +- ✅ React Frontend (auto-built and running) + +### Step 2: Start API (New Terminal) + +```bash +source venv/bin/activate +uvicorn api.main:app --reload --port 8000 +``` + +### Step 3: Start Consumer (New Terminal) + +```bash +cd consumer +python pipeline.py +``` + +## Access the System + +- **Frontend**: http://localhost:3000 +- **API**: http://localhost:8000 +- **Kafka**: localhost:9092 +- **Redis**: localhost:6379 + +## Using the Frontend + +1. **Frontend loads automatically** at http://localhost:3000 +2.
