Development Log

Phase 0: Project Initialization & Architecture Setup

Started: 2025-11-20 Completed: 2025-11-20 Duration: ~1 hour

What Was Built

• Comprehensive microservices directory structure
• Docker Desktop installation verification (version 28.5.1)
• Base docker-compose.yml with networks and volumes
• Local domain resolution (/etc/hosts)
• Git repository initialization
• Environment configuration (.env.example, .env)
• Initial documentation (README, CURRENT_PHASE, DEVELOPMENT_LOG)

Docker Configuration

• Docker Desktop version: 28.5.1
• Docker Compose version: 2.40.3-desktop.1
• Resources: Available (Docker already installed and configured)

Local Domains Configured

• voiceassist.local
• nextcloud.local
• keycloak.local
• api.voiceassist.local
• voice.voiceassist.local
• medical-kb.voiceassist.local
• admin.voiceassist.local
• docs.voiceassist.local
• prometheus.voiceassist.local
• grafana.voiceassist.local

Key Decisions

• Using Docker Compose for Phases 0-10
• Deferring Kubernetes to Phases 11-14
• Local domains via /etc/hosts (not DNS)
• Microservices architecture from day one
• Removed obsolete version: field from docker-compose.yml

Generated Secrets

• Postgres password: Generated (32 chars hex)
• Redis password: Generated (32 chars hex)
• SECRET_KEY: Generated (64 chars hex)
• JWT_SECRET: Generated (64 chars hex)

Issues Encountered

• Docker Desktop was installed but not running - resolved by launching it with open -a Docker
• Docker Compose warned about obsolete version attribute - removed it
• tree command not available - used find as alternative

Phase 1: Core Infrastructure & Database Setup

Started: 2025-11-20 Completed: 2025-11-20 Duration: ~2 hours

What Was Built

• PostgreSQL 16 with pgvector extension
• Redis 7 with persistence and password authentication
• Qdrant v1.7.4 for vector storage
• FastAPI server with comprehensive structure
• Health check endpoints (/health, /ready, /metrics)
• Alembic database migration system
• Core database tables (users, sessions, messages)

Services Configuration

• PostgreSQL: Port 5432, pgvector v0.8.1, UUID support
• Redis: Port 6379, AOF persistence enabled
• Qdrant: Port 6333 (HTTP), 6334 (gRPC)
• FastAPI Server: Port 8000, Python 3.11

Database Schema

users table:

• id (UUID), email, full_name, hashed_password
• is_active, is_admin, nextcloud_user_id
• created_at, updated_at, last_login

sessions table:

• id (UUID), user_id (FK), title, context (JSONB)
• message_count, created_at, updated_at, ended_at

messages table:

• id (UUID), session_id (FK), role, content
• tool_calls (JSONB), tool_results (JSONB)
• tokens, model, metadata (JSONB), contains_phi
• created_at

Key Decisions

• Used pgvector/pgvector:pg16 for built-in vector support
• Implemented comprehensive health checks with start_period
• Fixed Qdrant health check to use bash TCP connection test
• Structured FastAPI app with core, api, models separation
• Alembic for database migrations

Issues Encountered & Resolved

• Qdrant health check initially failed - fixed by using TCP connection test instead of curl/wget
• Alembic files not in Docker container - updated Dockerfile to copy them
• Redis health check needed proper auth - added password to command

Testing Results

• All services start and become healthy
• Health endpoint returns status and version
• Ready endpoint confirms all DB connections
• Database migrations run successfully
• All tables created with proper indexes

Next Phase

Phase 2: Security Foundation & Nextcloud Integration

• Install Nextcloud
• Set up Keycloak for SSO
• Implement JWT authentication
• Configure HTTPS
• Add MFA support
