From 4cbce89129a26a58d056b89b6f7cbbe8d9fdcd19 Mon Sep 17 00:00:00 2001 From: "dolgolyov.alexei" Date: Thu, 19 Mar 2026 14:52:21 +0300 Subject: [PATCH] =?UTF-8?q?Phase=207:=20Hardening=20=E2=80=94=20logging,?= =?UTF-8?q?=20security,=20Docker,=20production=20readiness?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Backend: - Structured JSON logging (python-json-logger) with request ID correlation - RequestIDMiddleware (server-generated UUID, no client trust) - Global exception handlers: AppException, RequestValidationError, generic 500 — all return consistent {"error": {code, message, request_id}} format - Async rate limiting with lock + stale key eviction on auth endpoints - Health endpoint checks DB connectivity, returns version + status - Custom exception classes (NotFoundException, ForbiddenException, etc.) - OpenAPI docs with tag descriptions, conditional URL (disabled in production) - LOG_LEVEL, DOCS_ENABLED, RATE_LIMIT_* settings added Docker: - Backend: multi-stage build (builder + runtime), non-root user, HEALTHCHECK - Frontend: removed dead user, HEALTHCHECK directive - docker-compose: restart policies, healthchecks, Redis service, named volumes for uploads/PDFs, rate limit env vars forwarded - Alembic migrations run only in Dockerfile CMD (removed from lifespan) Nginx: - server_tokens off - CSP, Referrer-Policy, Permissions-Policy headers - HSTS ready (commented, enable with TLS) Config & Docs: - .env.production.example with production-ready settings - CLAUDE.md project conventions (structure, workflow, naming, how-to) - .env.example updated with new variables Review fixes applied: - Rate limiter: async lock prevents race condition, stale key eviction - Request ID: always server-generated (no log injection) - Removed duplicate alembic migration from lifespan - Removed dead app user from frontend Dockerfile - Health check logs DB errors - Rate limit env vars forwarded in docker-compose Co-Authored-By: Claude Opus 4.6 (1M context) --- .env.example | 8 ++++ .env.production.example | 32 +++++++++++++ CLAUDE.md | 83 ++++++++++++++++++++++++++++++++++ GeneralPlan.md | 4 +- backend/Dockerfile | 29 ++++++++++-- backend/app/api/v1/auth.py | 3 ++ backend/app/api/v1/router.py | 23 +++++++++- backend/app/config.py | 5 ++ backend/app/core/exceptions.py | 25 ++++++++++ backend/app/core/logging.py | 24 ++++++++++ backend/app/core/middleware.py | 21 +++++++++ backend/app/core/rate_limit.py | 39 ++++++++++++++++ backend/app/main.py | 79 +++++++++++++++++++++++++++++--- backend/pyproject.toml | 1 + docker-compose.yml | 34 ++++++++++++++ frontend/Dockerfile | 3 ++ nginx/nginx.conf | 7 +++ plans/phase-7-hardening.md | 80 ++++++++++++++++++++++++++++++++ 18 files changed, 485 insertions(+), 15 deletions(-) create mode 100644 .env.production.example create mode 100644 CLAUDE.md create mode 100644 backend/app/core/exceptions.py create mode 100644 backend/app/core/logging.py create mode 100644 backend/app/core/middleware.py create mode 100644 backend/app/core/rate_limit.py create mode 100644 plans/phase-7-hardening.md diff --git a/.env.example b/.env.example index c120c93..414cd9f 100644 --- a/.env.example +++ b/.env.example @@ -18,6 +18,14 @@ REFRESH_TOKEN_EXPIRE_HOURS=24 ANTHROPIC_API_KEY=sk-ant-your-key-here CLAUDE_MODEL=claude-sonnet-4-20250514 +# Logging & Docs +LOG_LEVEL=INFO +DOCS_ENABLED=true + +# Rate limiting +RATE_LIMIT_REQUESTS=20 +RATE_LIMIT_WINDOW_SECONDS=60 + # Admin seed FIRST_ADMIN_EMAIL=admin@example.com FIRST_ADMIN_USERNAME=admin diff --git a/.env.production.example b/.env.production.example new file mode 100644 index 0000000..fe5bac1 --- /dev/null +++ b/.env.production.example @@ -0,0 +1,32 @@ +# PostgreSQL +POSTGRES_USER=ai_assistant +POSTGRES_PASSWORD=CHANGE_ME_STRONG_PASSWORD +POSTGRES_DB=ai_assistant + +# Backend +DATABASE_URL=postgresql+asyncpg://ai_assistant:CHANGE_ME_STRONG_PASSWORD@postgres:5432/ai_assistant +SECRET_KEY=CHANGE_ME_RANDOM_64_CHAR_STRING +BACKEND_CORS_ORIGINS=["https://yourdomain.com"] +ENVIRONMENT=production + +# Auth +ACCESS_TOKEN_EXPIRE_MINUTES=15 +REFRESH_TOKEN_EXPIRE_DAYS=30 +REFRESH_TOKEN_EXPIRE_HOURS=24 + +# AI +ANTHROPIC_API_KEY=sk-ant-your-production-key +CLAUDE_MODEL=claude-sonnet-4-20250514 + +# Logging & Docs +LOG_LEVEL=WARNING +DOCS_ENABLED=false + +# Rate limiting +RATE_LIMIT_REQUESTS=20 +RATE_LIMIT_WINDOW_SECONDS=60 + +# Admin seed (change after first run) +FIRST_ADMIN_EMAIL=admin@yourdomain.com +FIRST_ADMIN_USERNAME=admin +FIRST_ADMIN_PASSWORD=CHANGE_ME_STRONG_ADMIN_PASSWORD diff --git a/CLAUDE.md b/CLAUDE.md new file mode 100644 index 0000000..7d23f02 --- /dev/null +++ b/CLAUDE.md @@ -0,0 +1,83 @@ +# AI Assistant -
