Testing & Verification

Service Health Checks

# All services healthy
docker compose ps

# Health endpoint
curl http://localhost:8000/health
# Returns: {"status":"healthy","version":"0.1.0","timestamp":...}

# Readiness endpoint
curl http://localhost:8000/ready
# Returns: {"status":"ready","checks":{"postgres":true,"redis":true,"qdrant":true},...}

Database Verification

# List tables
docker compose exec postgres psql -U voiceassist -d voiceassist -c "\dt"
# Returns: alembic_version, messages, sessions, users

# List extensions
docker compose exec postgres psql -U voiceassist -d voiceassist -c "\dx"
# Returns: pg_trgm, plpgsql, uuid-ossp, vector

Migration Status

# Check migration status
docker compose exec voiceassist-server alembic current
# Returns: 001 (head)

Issues Encountered & Resolutions

Issue 1: Qdrant Health Check Failure

Problem: Qdrant health check failing with curl/wget Root Cause: curl/wget not available in Qdrant container Solution: Changed to bash TCP connection test

test: ["CMD-SHELL", "timeout 2 bash -c '</dev/tcp/localhost/6333' || exit 1"]

Issue 2: Alembic Files Not in Container

Problem: Alembic migrations not running - files missing Root Cause: Dockerfile didn't copy alembic files Solution: Updated Dockerfile to include alembic.ini and alembic/ directory

Issue 3: Redis Health Check Authentication

Problem: Redis health check failing with auth error Root Cause: Password not included in health check command Solution: Modified health check to use authenticated ping
