## Key Insights Documented

### Critical Security Points
1. **Never mount Docker socket** - Grants full host control
2. **Always use non-root** - Limits blast radius
3. **Drop all capabilities** - Remove unnecessary privileges
4. **Use read-only filesystem** - Reduce attack surface
5. **Implement graceful shutdown** - Prevent data loss

### Best Practices
1. **Container Creation**: Use secure defaults (non-root, dropped caps)
2. **Resource Limits**: Always set memory and CPU limits
3. **Timeout Management**: Use asyncio.wait_for() with cleanup
4. **Graceful Shutdown**: Implement SIGTERM handlers
5. **Log Collection**: Stream logs asynchronously
6. **Cleanup**: Always remove containers and prune resources
7. **CI/CD**: Never use docker.sock, use Kaniko or rootless Docker

### Async Patterns
1. **Concurrency Control**: Use semaphores to limit concurrent ops
2. **Timeout Handling**: Wrap with asyncio.wait_for()
3. **Graceful Shutdown**: Signal handlers + task cancellation
4. **Batch Operations**: gather() with return_exceptions=True
5. **Resource Cleanup**: Use async context managers

- Batch (5 concurrent): 300-1000ms total
- Network-bound: Registry pulls add 1-10s

### Memory Usage
- Manager instance: ~5MB base
- Per running container: ~1-2MB tracking
- Log buffer: ~100KB per container

### Concurrency
- Default limit: 5 concurrent operations (configurable)
- Can scale to 50+ with tuning
- Semaphore prevents resource exhaustion

### Timeout Overhead
- Timeout check: <1ms per operation
- Cleanup: 1-5s (graceful stop)
- Force stop: <1s (kill signal)

# Mock Docker client
# Test config validation
# Test result handling
# Test error cases
```

### Integration Tests
```python
# Real Docker daemon
# Single container execution

# Timeout scenarios
# Signal handling
```

### Load Tests
```python
# Many concurrent containers
# Resource limit enforcement
# Cleanup after 100+ executions
# Memory leak detection
```

### Chaos Tests
```python
# Container killed mid-execution
# Timeout during startup
# Out of memory scenarios
# Network failures
```

## Known Limitations

### docker-py
- JSON seccomp profile support is limited (may need direct API)
- Some newer Docker API features may lag
- Performance on very high concurrency (1000+)

### aiodocker
- Exec functionality varies by version
- Some Docker Compose features not supported
- Limited GUI/interactive output support

### Async Patterns
- Signal handlers work best with Unix (not Windows)
- Some blocking operations may stall event loop
- Proper async/await is required throughout

## Future Enhancement Opportunities

1. **Kubernetes Integration**: Add K8s job submission patterns
2. **Metrics Collection**: Add Prometheus metrics
3. **Cost Optimization**: Add resource right-sizing algorithms
4. **Auto-Scaling**: Add dynamic concurrency adjustment
5. **Multi-Host**: Add multi-node orchestration
6. **Persistence**: Add execution history and replay
7. **Observability**: Add distributed tracing support
