From 84e0370a1ddd30a9e44ef6c40faf5e6cd13e0269 Mon Sep 17 00:00:00 2001 From: Jean-Philippe Brule Date: Sat, 8 Nov 2025 11:03:25 -0500 Subject: [PATCH] Add complete production deployment infrastructure with full observability MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Transforms the AI agent from a proof-of-concept into a production-ready, fully observable system with Docker deployment, PostgreSQL persistence, OpenTelemetry tracing, Prometheus metrics, and rate limiting. Ready for immediate production deployment. ## Infrastructure & Deployment (New) **Docker Multi-Container Architecture:** - docker-compose.yml: 4-service stack (API, PostgreSQL, Ollama, Langfuse) - Dockerfile: Multi-stage build (SDK for build, runtime for production) - .dockerignore: Optimized build context (excludes 50+ unnecessary files) - .env: Environment configuration with auto-generated secrets - docker/configs/init-db.sql: PostgreSQL initialization with 2 databases + seed data - scripts/deploy.sh: One-command deployment with health validation **Network Architecture:** - API: Ports 6000 (gRPC/HTTP2) and 6001 (HTTP/1.1) - PostgreSQL: Port 5432 with persistent volumes - Ollama: Port 11434 with model storage - Langfuse: Port 3000 with observability UI ## Database Integration (New) **Entity Framework Core + PostgreSQL:** - AgentDbContext: Full EF Core context with 3 entities - Entities/Conversation: JSONB storage for AI conversation history - Entities/Revenue: Monthly revenue data (17 months seeded: 2024-2025) - Entities/Customer: Customer database (15 records with state/tier) - Migrations: InitialCreate migration with complete schema - Auto-migration on startup with error handling **Database Schema:** - agent.conversations: UUID primary key, JSONB messages, timestamps with indexes - agent.revenue: Serial ID, month/year unique index, decimal amounts - agent.customers: Serial ID, state/tier indexes for query performance - Seed data: $2.9M total revenue, 15 enterprise/professional/starter tier customers **DatabaseQueryTool Rewrite:** - Changed from in-memory simulation to real PostgreSQL queries - All 5 methods now use async Entity Framework Core - GetMonthlyRevenue: Queries actual revenue table with year ordering - GetRevenueRange: Aggregates multiple months with proper filtering - CountCustomersByState/Tier: Real customer counts from database - GetCustomers: Filtered queries with Take(10) pagination ## Observability (New) **OpenTelemetry Integration:** - Full distributed tracing with Langfuse OTLP exporter - ActivitySource: "Svrnty.AI.Agent" and "Svrnty.AI.Ollama" - Basic Auth to Langfuse with environment-based configuration - Conditional tracing (only when Langfuse keys configured) **Instrumented Components:** ExecuteAgentCommandHandler: - agent.execute (root span): Full conversation lifecycle - Tags: conversation_id, prompt, model, success, iterations, response_preview - tools.register: Tool initialization with count and names - llm.completion: Each LLM call with iteration number - function.{name}: Each tool invocation with arguments, results, success/error - Database persistence span for conversation storage OllamaClient: - ollama.chat: HTTP client span with model and message count - Tags: latency_ms, estimated_tokens, has_function_calls, has_tools - Timing: Tracks start to completion for performance monitoring **Span Hierarchy Example:** ``` agent.execute (2.4s) ├── tools.register (12ms) [tools.count=7] ├── llm.completion (1.2s) [iteration=0] ├── function.Add (8ms) [arguments={a:5,b:3}, result=8] └── llm.completion (1.1s) [iteration=1] ``` **Prometheus Metrics (New):** - /metrics endpoint for Prometheus scraping - http_server_request_duration_seconds: API latency buckets - http_client_request_duration_seconds: Ollama call latency - ASP.NET Core instrumentation: Request count, status codes, methods - HTTP client instrumentation: External call reliability ## Production Features (New) **Rate Limiting:** - Fixed window: 100 requests/minute per client - Partition key: Authenticated user or host header - Queue: 10 requests with FIFO processing - Rejection: HTTP 429 with JSON error and retry-after metadata - Prevents API abuse and protects Ollama backend **Health Checks:** - /health: Basic liveness check - /health/ready: Readiness with PostgreSQL validation - Database connectivity test using AspNetCore.HealthChecks.NpgSql - Docker healthcheck directives with retries and start periods **Configuration Management:** - appsettings.Production.json: Container-optimized settings - Environment-based configuration for all services - Langfuse keys optional (degrades gracefully without tracing) - Connection strings externalized to environment variables ## Modified Core Components **ExecuteAgentCommandHandler (Major Changes):** - Added dependency injection: AgentDbContext, MathTool, DatabaseQueryTool, ILogger - Removed static in-memory conversation store - Added full OpenTelemetry instrumentation (5 span types) - Database persistence: Conversations saved to PostgreSQL - Error tracking: Tags for error type, message, success/failure - Tool registration moved to DI (no longer created inline) **OllamaClient (Enhancements):** - Added OpenTelemetry ActivitySource instrumentation - Latency tracking: Start time to completion measurement - Token estimation: Character count / 4 heuristic - Function call detection: Tags for has_function_calls - Performance metrics for SLO monitoring **Program.cs (Major Expansion):** - Added 10 new using statements (RateLimiting, OpenTelemetry, EF Core) - Database configuration: Connection string and DbContext registration - OpenTelemetry setup: Metrics + Tracing with conditional Langfuse export - Rate limiter configuration with custom rejection handler - Tool registration via DI (MathTool as singleton, DatabaseQueryTool as scoped) - Health checks with PostgreSQL validation - Auto-migration on startup with error handling - Prometheus metrics endpoint mapping - Enhanced console output with all endpoints listed **Svrnty.Sample.csproj (Package Additions):** - Npgsql.EntityFrameworkCore.PostgreSQL 9.0.2 - Microsoft.EntityFrameworkCore.Design 9.0.0 - OpenTelemetry 1.10.0 - OpenTelemetry.Exporter.OpenTelemetryProtocol 1.10.0 - OpenTelemetry.Extensions.Hosting 1.10.0 - OpenTelemetry.Instrumentation.Http 1.10.0 - OpenTelemetry.Instrumentation.EntityFrameworkCore 1.10.0-beta.1 - OpenTelemetry.Instrumentation.AspNetCore 1.10.0 - OpenTelemetry.Exporter.Prometheus.AspNetCore 1.10.0-beta.1 - AspNetCore.HealthChecks.NpgSql 9.0.0 ## Documentation (New) **DEPLOYMENT_README.md:** - Complete deployment guide with 5-step quick start - Architecture diagram with all 4 services - Access points with all endpoints listed - Project structure overview - OpenTelemetry span hierarchy documentation - Database schema description - Troubleshooting commands - Performance characteristics and implementation details **Enhanced README.md:** - Added production deployment section - Docker Compose instructions - Langfuse configuration steps - Testing examples for all endpoints ## Access Points (Complete List) - HTTP API: http://localhost:6001/api/command/executeAgent - gRPC API: http://localhost:6000 (via Grpc.AspNetCore.Server.Reflection) - Swagger UI: http://localhost:6001/swagger - Prometheus Metrics: http://localhost:6001/metrics ⭐ NEW - Health Check: http://localhost:6001/health ⭐ NEW - Readiness Check: http://localhost:6001/health/ready ⭐ NEW - Langfuse UI: http://localhost:3000 ⭐ NEW - Ollama API: http://localhost:11434 ⭐ NEW ## Deployment Workflow 1. `./scripts/deploy.sh` -
