91f7b9d129 feat(docker): add multi-container cluster deployment with CLI management
Add comprehensive Docker cluster orchestration with horizontal scaling support.

CLI Commands:
- crwl server start/stop/restart/status/scale/logs
- Auto-detection: Single (N=1) → Swarm (N>1) → Compose (N>1 fallback)
- Support for 1-100 container replicas with zero-downtime scaling

Infrastructure:
- Nginx load balancing (round-robin API, sticky sessions monitoring)
- Redis-based container discovery via heartbeats (30s interval)
- Real-time monitoring dashboard with cluster-wide visibility
- WebSocket aggregation from all containers

Security & Stability Fixes (12 critical issues):
- Add timeout protection to browser pool locks (prevent deadlocks)
- Implement Redis retry logic with exponential backoff
- Add container ID validation (prevent Redis key injection)
- Add CLI input sanitization (prevent shell injection)
- Add file locking for state management (prevent corruption)
- Fix WebSocket resource leaks and connection cleanup
- Add graceful degradation and circuit breakers

Configuration:
- RedisTTLConfig dataclass with environment variable support
- Template-based docker-compose.yml and nginx.conf generation
- Comprehensive error handling with actionable messages

Documentation:
- AGENT.md: Complete DevOps context for AI assistants
- MULTI_CONTAINER_ARCHITECTURE.md: Technical architecture guide
- Reorganized docs into deploy/docker/docs/

b97eaeea4c feat(docker): implement smart browser pool with 10x memory efficiency
Major refactoring to eliminate memory leaks and enable high-scale crawling:

- **Smart 3-Tier Browser Pool**:
  - Permanent browser (always-ready default config)
  - Hot pool (configs used 3+ times, longer TTL)
  - Cold pool (new/rare configs, short TTL)
  - Auto-promotion: cold → hot after 3 uses
  - 100% pool reuse achieved in tests

- **Container-Aware Memory Detection**:
  - Read cgroup v1/v2 memory limits (not host metrics)
  - Accurate memory pressure detection in Docker
  - Memory-based browser creation blocking

- **Adaptive Janitor**:
  - Dynamic cleanup intervals (10s/30s/60s based on memory)
  - Tiered TTLs: cold 30-300s, hot 120-600s
  - Aggressive cleanup at high memory pressure

- **Unified Pool Usage**:
  - All endpoints now use pool (/html, /screenshot, /pdf, /execute_js, /md, /llm)
  - Fixed config signature mismatch (permanent browser matches endpoints)
  - get_default_browser_config() helper for consistency

- **Configuration**:
  - Reduced idle_ttl: 1800s → 300s (30min → 5min)
  - Fixed port: 11234 → 11235 (match Gunicorn)

**Performance Results** (from stress tests):
- Memory: 10x reduction (500-700MB × N → 270MB permanent)
- Latency: 30-50x faster (<100ms pool hits vs 3-5s startup)
- Reuse: 100% for default config, 60%+ for variants
- Capacity: 100+ concurrent requests (vs ~20 before)
- Leak: 0 MB/cycle (stable across tests)

**Test Infrastructure**:
- 7-phase sequential test suite (tests/)
- Docker stats integration + log analysis
- Pool promotion verification
- Memory leak detection
- Full endpoint coverage

Fixes memory issues reported in production deployments.

159207b86f feat(docker): Add temperature and base_url parameters for LLM configuration. ref #1035
Implement hierarchical configuration for LLM parameters with support for:
  - Temperature control (0.0-2.0) to adjust response creativity
  - Custom base_url for proxy servers and alternative endpoints
  - 4-tier priority: request params > provider env > global env > defaults

  Add helper functions in utils.py, update API schemas and handlers,
  support environment variables (LLM_TEMPERATURE, OPENAI_TEMPERATURE, etc.),
  and provide comprehensive documentation with examples.

95051020f4 fix(docker): Fix LLM API key handling for multi-provider support
Previously, the system incorrectly used OPENAI_API_KEY for all LLM providers
due to a hardcoded api_key_env fallback in config.yml. This caused authentication
errors when using non-OpenAI providers like Gemini.

Changes:
- Remove api_key_env from config.yml to let litellm handle provider-specific env vars
- Simplify get_llm_api_key() to return None, allowing litellm to auto-detect keys
- Update validate_llm_provider() to trust litellm's built-in key detection
- Update documentation to reflect the new automatic key handling

The fix leverages litellm's existing capability to automatically find the correct
environment variable for each provider (OPENAI_API_KEY, GEMINI_API_TOKEN, etc.)
without manual configuration.

ff6ea41ac3 feat(docker): add flexible LLM provider configuration
- Support LLM_PROVIDER env var to override default provider (openai/gpt-4o-mini)
- Add optional 'provider' parameter to API endpoints for per-request overrides
- Implement provider validation to ensure API keys exist
- Update documentation and examples with new configuration options

Closes the need to hardcode providers in config.yml

94e9959fe0 feat(docker-api): add job-based polling endpoints for crawl and LLM tasks
Implements new asynchronous endpoints for handling long-running crawl and LLM tasks:
- POST /crawl/job and GET /crawl/job/{task_id} for crawl operations
- POST /llm/job and GET /llm/job/{task_id} for LLM operations
- Added Redis-based task management with configurable TTL
- Moved schema definitions to dedicated schemas.py
- Added example polling client demo_docker_polling.py

This change allows clients to handle long-running operations asynchronously through a polling pattern rather than holding connections open.
