Task 2: Create Project Directory Structure

# Navigate to home directory
cd ~

# Verify VoiceAssist directory exists (from previous planning)
ls -la VoiceAssist/

# Create comprehensive microservices structure
cd ~/VoiceAssist

# Create service directories
mkdir -p services/{api-gateway,voice-proxy,medical-kb,admin-api,auth-service}
mkdir -p services/{file-indexer,calendar-email,guideline-scraper,medical-calculator,phi-detection}

# Create infrastructure directories
mkdir -p infrastructure/{docker,kubernetes,terraform,ansible}
mkdir -p infrastructure/docker/compose-files

# Create web app directories (React frontends)
mkdir -p web-apps/{client,admin,docs}
mkdir -p web-apps/client/{src,public}
mkdir -p web-apps/admin/{src,public}
mkdir -p web-apps/docs/{content,public}

# Create Nextcloud app directories
mkdir -p nextcloud-apps/{voiceassist-client,voiceassist-admin,voiceassist-docs}

# Create shared libraries
mkdir -p shared/{models,utils,config}

# Create test directories
mkdir -p tests/{unit,integration,e2e,load}

# Create data directories
mkdir -p data/{postgres,redis,qdrant,uploads,backups,logs}

# Create scripts directory
mkdir -p scripts/{dev,deploy,backup}

# Create docs/phases if not exists
mkdir -p docs/phases

# Verify structure
tree -L 2 ~/VoiceAssist

Task 3: Install Docker Desktop

# Check if Docker is already installed
docker --version 2>/dev/null

# If not installed:
# Download Docker Desktop for Mac from:
# https://www.docker.com/products/docker-desktop/

# Or install via Homebrew Cask
brew install --cask docker

# Launch Docker Desktop
open -a Docker

# Wait for Docker to start (whale icon in menu bar)
# This may take a minute

# Verify Docker is running
docker ps
# Should show empty list (no containers yet)

# Verify Docker Compose
docker compose version
# Should show version 2.x or higher

# Configure Docker Desktop resources
# Open Docker Desktop → Settings → Resources
# Recommended settings:
# - CPUs: 4-6
# - Memory: 8-12 GB
# - Swap: 2 GB
# - Disk: 60 GB

# Apply and Restart if you changed settings

Task 4: Create Base docker-compose.yml

cd ~/VoiceAssist

Create docker-compose.yml:

version: "3.8"

# Networks
networks:
  voiceassist-network:
    driver: bridge

  database-network:
    driver: bridge
    internal: true # Database network is internal-only

# Volumes for data persistence

services:
  # Services will be added in subsequent phases
  # This is the skeleton structure

  # Phase 1 will add:
  # - postgres
  # - redis
  # - qdrant

  # Phase 2 will add:
  # - nextcloud
  # - keycloak
  # - auth-service

  # Phase 3 will add:
  # - api-gateway
  # - voice-proxy
  # - medical-kb

  # Placeholder service to test setup
  hello-world:
    image: hello-world
    networks:
      - voiceassist-network

Test the compose file:

# Validate compose file
docker compose config

# Run hello-world test
docker compose up hello-world

# Should see "Hello from Docker!" message

# Clean up
docker compose down

Task 5: Set Up Local Domains

Edit /etc/hosts to add local domain resolution:

# Backup current hosts file
sudo cp /etc/hosts /etc/hosts.backup

# Add VoiceAssist domains
sudo tee -a /etc/hosts <<EOF

# VoiceAssist Local Development
127.0.0.1 voiceassist.local

EOF

# Verify
cat /etc/hosts | grep voiceassist

# Test resolution
ping -c 1 voiceassist.local
# Should resolve to 127.0.0.1

# Check Docker is running
docker info | head -n 10

# Should show Docker version, containers, images, etc.

# Test Docker Compose
docker compose version
# Should show version 2.x

# Run test container
docker run --rm hello-world
# Should see "Hello from Docker!"

Test 2: Verify Directory Structure

# Check all key directories exist
cd ~/VoiceAssist
ls -la

# Verify services directory
ls -la services/

# Verify infrastructure directory
ls -la infrastructure/

# Verify web-apps directory
ls -la web-apps/

# Verify docs directory
ls -la docs/

# Check directory tree
tree -L 2 -d .

Test 3: Verify Local Domains

# Test DNS resolution
ping -c 1 voiceassist.local
ping -c 1 nextcloud.local
ping -c 1 api.voiceassist.local

# All should resolve to 127.0.0.1

Test 4: Verify Git Repository

# Check git status
git status

# Should show clean working tree or initial commit

# Check git log
git log --oneline

# Should show initial commit

Test 5: Verify Environment Configuration

grep "OPENAI_API_KEY=sk-" .env && echo "✅ OpenAI key set" || echo "⚠️  OpenAI key not set - add it now!"

Documentation Updates

Update these files:

CURRENT_PHASE.md
- Mark Phase 0 as complete
- Add completion date
- Note next phase
DEVELOPMENT_LOG.md (create if doesn't exist)

cat > DEVELOPMENT_LOG.md <<'EOF'

Section B: Kubernetes Migration Notes

This section documents how Phase 0 will translate to Kubernetes in Phases 11-14.

Kubernetes Equivalent Concepts

Docker Compose → Kubernetes:

Compose Concept	Kubernetes Equivalent
services	Deployments + Services
networks	Network Policies
volumes	PersistentVolumes + PersistentVolumeClaims
environment variables	ConfigMaps + Secrets
docker-compose.yml	Multiple YAML manifests
depends_on	InitContainers or readiness probes
ports	Service type LoadBalancer/NodePort

Directory Structure for Kubernetes

In Phase 11, add:

infrastructure/kubernetes/
├── base/
│   ├── namespaces.yaml
│   ├── network-policies.yaml
│   └── storage-classes.yaml
├── deployments/
│   ├── postgres-statefulset.yaml
│   ├── redis-deployment.yaml
│   ├── qdrant-statefulset.yaml
│   └── ... (all services)
├── services/
│   ├── postgres-service.yaml
│   ├── redis-service.yaml
│   └── ... (all services)
├── configmaps/
│   └── app-config.yaml
├── secrets/
│   └── app-secrets.yaml (encrypted)
└── ingress/
    └── ingress.yaml

Migration Process (Phase 11)

Convert Compose to K8s Manifests
- Use kompose convert as starting point
- Manually refine for production
- Add resource limits and requests
- Add liveness/readiness probes
Add Kubernetes-Specific Features
- HorizontalPodAutoscaler
- PodDisruptionBudget
- NetworkPolicies
- ResourceQuotas
Service Mesh Integration
- Install Linkerd
- Inject sidecars
- Configure mTLS
- Set up traffic policies

Local Kubernetes Testing

Options for local K8s testing:

K3s (lightweight, recommended)
Minikube (full-featured)
Docker Desktop K8s (simplest)

What Stays the Same

Application code (no changes)
Docker images (same images)
Environment variables (same names)
Service discovery (DNS-based)
Database schemas
API contracts

What Changes

Orchestration layer (Compose → K8s)
Configuration method (env files → ConfigMaps/Secrets)
Networking (Compose networks → K8s Services)
Storage (Docker volumes → PersistentVolumes)
Observability integration (Prometheus operator)
Service-to-service auth (mTLS via service mesh)

Estimated Migration Time

Phase 11: Create K8s manifests (6-8 hours)
Phase 12: Test locally with K3s (4-6 hours)
Phase 13: Production prep (6-8 hours)
Phase 14: Deploy to production (6-8 hours)

Total: ~22-30 hours for K8s migration

Troubleshooting

Docker Desktop Won't Start

# Check if another Docker instance is running
ps aux | grep -i docker

# Kill any conflicting processes
pkill -9 -f docker

# Reset Docker Desktop
# Open Docker Desktop → Troubleshoot → Reset to factory defaults

# Restart
open -a Docker

Port Already in Use

# Find process using port
lsof -ti:8000

# Kill the process
kill -9 $(lsof -ti:8000)

/etc/hosts Permission Denied

# Use sudo
sudo vim /etc/hosts

# Or use tee
echo "127.0.0.1 voiceassist.local" | sudo tee -a /etc/hosts

Git Initialization Issues

# If git is not initialized
cd ~/VoiceAssist
git init

# If you get permission errors
sudo chown -R $(whoami) ~/VoiceAssist

Docker Compose Validation Errors

# Check syntax
docker compose config

# Validate against schema
docker compose config --quiet

# If errors, check YAML indentation

Exit Checklist
