Service Ports

Docker Network

All services communicate via vigil-net external network.

Internal hostnames:

• heuristics-service (Branch A)
• semantic-service (Branch B)
• prompt-guard-api (Branch C)
• vigil-presidio-pii or presidio-pii-api
• vigil-language-detector or language-detector
• vigil-clickhouse or clickhouse
• vigil-n8n or n8n
• web-ui-backend
• web-ui-frontend

Common Commands

Start All Services

docker-compose up -d

Start Services by Function

# 3-Branch Detection only
docker-compose up -d heuristics-service semantic-service prompt-guard-api

# PII Detection only
docker-compose up -d presidio-pii-api language-detector

# Monitoring only
docker-compose up -d clickhouse grafana

# Web UI only
docker-compose up -d web-ui-backend web-ui-frontend caddy

# Workflow engine
docker-compose up -d n8n

View Logs

# All services
docker-compose logs -f

# Specific service
docker-compose logs -f heuristics-service

# Last 100 lines
docker-compose logs --tail=100 n8n

# Multiple services
docker-compose logs -f heuristics-service semantic-service prompt-guard-api

Restart Services

# All
docker-compose restart

# Specific
docker-compose restart heuristics-service

# 3-Branch services
docker-compose restart heuristics-service semantic-service prompt-guard-api

Stop and Remove

# Stop all
docker-compose down

# Stop and remove volumes (DESTRUCTIVE!)
docker-compose down -v

Rebuild After Changes

# Rebuild all
docker-compose up --build -d

# Rebuild specific
docker-compose up --build -d heuristics-service

# Rebuild with no cache
docker-compose build --no-cache heuristics-service

Service Health Checks

Check Running Containers

docker ps
# Should show 11 containers: vigil-*, heuristics-service, semantic-service, etc.

Test Service Endpoints

# Branch A - Heuristics
curl http://localhost:5005/​health

# Branch B - Semantic
curl http://localhost:5006/​health

# Branch C - LLM Guard
curl http://localhost:8000/​health

# PII Detection
curl http://localhost:5001/​health

# Language Detection
curl http://localhost:5002/​health

# n8n
curl http://localhost:5678/​healthz

# ClickHouse
curl http://localhost:8123/​ping

# Grafana
curl -I http://localhost:3001

# Backend API
curl http://localhost:8787/​api/​files

# Proxy
curl -I http://localhost/​ui/

Check All Services Script

#!/​bin/​bash
# scripts/​health-check.sh

services=(
  "5005:Heuristics"
  "5006:Semantic"
  "8000:LLM Guard"
  "5001:Presidio"
  "5002:Language"
  "5678:n8n"
  "8123:ClickHouse"
  "3001:Grafana"
  "8787:Backend"
)

for svc in "${services[@]}"; do
  port="${svc%%:*}"
  name="${svc##*:}"
  if curl -s "http://localhost:$port/​health" > /​dev/​null 2>&1; then
    echo "✅ $name (:$port)"
  else
    echo "❌ $name (:$port)"
  fi
done

Docker Network

Inspect Network

docker network inspect vigil-net

Create Network (if missing)

docker network create vigil-net

Test Inter-Service Connectivity

# From n8n to heuristics
docker exec vigil-n8n curl -s http://heuristics-service:5005/​health

# From n8n to semantic
docker exec vigil-n8n curl -s http://semantic-service:5006/​health

# From n8n to prompt-guard
docker exec vigil-n8n curl -s http://prompt-guard-api:8000/​health

Volume Management

List Volumes

docker volume ls | grep vigil

Backup Volumes

# ClickHouse data
docker run --rm -v vigil_clickhouse_data:/​data -v $(pwd):/​backup alpine tar czf /​backup/​clickhouse-backup.tar.gz /​data

# n8n data
docker run --rm -v vigil_n8n_data:/​data -v $(pwd):/​backup alpine tar czf /​backup/​n8n-backup.tar.gz /​data

# Semantic embeddings
docker run --rm -v vigil_semantic_data:/​data -v $(pwd):/​backup alpine tar czf /​backup/​semantic-backup.tar.gz /​data

Remove Volumes (DESTRUCTIVE!)

docker volume rm vigil_clickhouse_data

Troubleshooting

Port Already in Use

# Find process using port
lsof -i :5005

# Kill process (if needed)
kill -9 <PID>

Service Won't Start

# Check logs
docker-compose logs heuristics-service

# Check network
docker network inspect vigil-net

# Verify environment variables
docker-compose config

# Check dependencies
docker-compose ps

Container Crashes

# View last logs before crash
docker logs --tail=100 heuristics-service

# Check restart count
docker ps -a | grep vigil

# Inspect container
docker inspect heuristics-service

Network Issues

# Restart networking
docker-compose down
docker network rm vigil-net
docker network create vigil-net
docker-compose up -d

Branch Timeout Issues

# Check branch timing in ClickHouse
docker exec vigil-clickhouse clickhouse-client -q "
  SELECT
    avg(branch_a_timing_ms) as a_avg,
    avg(branch_b_timing_ms) as b_avg,
    avg(branch_c_timing_ms) as c_avg
  FROM n8n_logs.events_processed
  WHERE timestamp > now() - INTERVAL 1 HOUR
"

# Check service resource usage
docker stats heuristics-service semantic-service prompt-guard-api

Development vs Production

Development (individual services)

# Backend dev server
cd services/​web-ui/​backend && npm run dev

# Frontend dev server
cd services/​web-ui/​frontend && npm run dev

# Heuristics dev
cd services/​heuristics-service && npm run dev

# Semantic dev
cd services/​semantic-service && python app.py

Production (Docker)

# Build and start all
docker-compose up --build -d

# Verify all healthy
./​scripts/​status.sh

Monitoring Resources

Container Stats

docker stats

Disk Usage

docker system df

Prune Unused Resources

# Remove unused containers, images, networks
docker system prune

# Remove volumes too (CAREFUL!)
docker system prune -a --volumes
