1.1 基础镜像选择

FLUX.1-dev-ControlNet-Union模型需要较高的计算资源，推荐使用包含CUDA的基础镜像：

FROM nvidia/cuda:11.7.1-cudnn8-runtime-ubuntu22.04

1.2 环境配置

安装系统依赖和Python环境：

# 设置时区
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

# 安装系统依赖
RUN apt-get update && apt-get install -y --no-install-recommends \
    python3.10 \
    python3-pip \
    python3-dev \
    build-essential \
    git \
    && rm -rf /var/lib/apt/lists/*

# 设置Python
RUN ln -s /usr/bin/python3.10 /usr/bin/python && \
    ln -s /usr/bin/pip3 /usr/bin/pip

# 升级pip
RUN pip install --upgrade pip

1.3 安装Python依赖

根据项目需求，安装必要的Python库：

# 安装PyTorch
RUN pip install torch==2.0.1 torchvision==0.15.2 torchaudio==2.0.2 --index-url https://download.pytorch.org/whl/cu117

# 安装diffusers及相关依赖

第二章：推理服务开发

2.1 FastAPI服务架构设计

使用FastAPI构建推理服务，支持单图推理和批量推理两种模式：

from fastapi import FastAPI, UploadFile, File, HTTPException, BackgroundTasks
from fastapi.responses import FileResponse
from pydantic import BaseModel
import torch
import os
import uuid
from PIL import Image
from io import BytesIO
import asyncio
from batch_processor import FluxControlNetModel, batch_process

app = FastAPI(title="FLUX.1-dev-ControlNet-Union Inference Service")

# 全局模型实例
model = None

# 任务队列
task_queue = asyncio.Queue()
processing_tasks = {}

# 配置
class Settings(BaseModel):
    model_dir: str = "/app/models"
    base_model_name: str = "base_model"
    controlnet_model_name: str = "controlnet_model"
    device: str = "cuda" if torch.cuda.is_available() else "cpu"
    batch_size: int = 16
    max_pending_tasks: int = 1000

settings = Settings()

# 初始化模型
@app.on_event("startup")
async def startup_event():
    global model
    print(f"Loading model on {settings.device}...")
    # 实际实现中应加载模型权重
    model = FluxControlNetModel(json.load(open("config.json")))
    print("Model loaded successfully")
    
    # 启动任务处理协程
    asyncio.create_task(process_tasks())

# 单图推理请求模型
class InferenceRequest(BaseModel):
    prompt: str
    control_mode: int = 0
    controlnet_conditioning_scale: float = 0.5
    num_inference_steps: int = 24
    guidance_scale: float = 3.5

2.2 单图推理接口

实现同步单图推理接口，适用于实时性要求高的场景：

@app.post("/infer", response_class=FileResponse)
async def infer(
    file: UploadFile = File(...),
    prompt: str = "A high-quality image",
    control_mode: int = 0,
    controlnet_conditioning_scale: float = 0.5,
    num_inference_steps: int = 24,
    guidance_scale: float = 3.5
):
    if not model:
        raise HTTPException(status_code=503, detail="Model not loaded yet")
    
    # 验证控制模式
    valid_modes = {0, 1, 2, 3, 4, 6}  # 排除gray模式(5)，当前有效性低
    if control_mode not in valid_modes:
        raise HTTPException(status_code=400, detail=f"Invalid control_mode. Valid modes: {valid_modes}")
    
    try:
        # 读取控制图像
        control_image = Image.open(BytesIO(await file.read())).convert("RGB")
        
        # 执行推理
        # 实际实现中应调用模型推理函数
        result_image = Image.new("RGB", control_image.size, color="red")  # 占位
        
        # 保存结果
        output_path = f"/tmp/{uuid.uuid4()}.png"
        result_image.save(output_path)
        
        return FileResponse(output_path, media_type="image/png")
    except Exception as e:
        raise HTTPException(status_code=500, detail=f"Inference failed: {str(e)}")

2.3 批量推理接口

实现异步批量推理接口，支持任务队列和状态查询：

@app.post("/batch-infer")
async def batch_infer(
    background_tasks: BackgroundTasks,
    prompt_file: UploadFile = File(...),
    input_dir: str = "/app/input",
    output_dir: str = "/app/output"
):
    if not model:
        raise HTTPException(status_code=503, detail="Model not loaded yet")
    
    # 检查队列状态
    if task_queue.qsize() >= settings.max_pending_tasks:
        raise HTTPException(status_code=429, detail="Too many pending tasks")
    
    # 生成任务ID
    task_id = str(uuid.uuid4())
    
    # 保存提示词文件
    os.makedirs("/app/prompts", exist_ok=True)
    prompt_path = f"/app/prompts/{task_id}.txt"
    with open(prompt_path, "wb") as f:
        f.write(await prompt_file.read())
    
    # 创建输入输出目录
    os.makedirs(input_dir, exist_ok=True)
    os.makedirs(output_dir, exist_ok=True)
    
    # 添加任务到队列
    task = {
        "task_id": task_id,
        "input_dir": input_dir,
        "output_dir": output_dir,
        "prompt_file": prompt_path,
        "status": "pending",
        "progress": 0,
        "total": None,
        "result": None
    }
    processing_tasks[task_id] = task
    await task_queue.put(task)
    
    return {"task_id": task_id, "status": "pending"}

# 任务状态查询接口
@app.get("/batch-infer/{task_id}")
async def get_batch_status(task_id: str):
    if task_id not in processing_tasks:
        raise HTTPException(status_code=404, detail="Task not found")
    
    task = processing_tasks[task_id]
    return {
        "task_id": task_id,
        "status": task["status"],
        "progress": task["progress"],
        "total": task["total"],
        "result": task["result"]
    }

# 任务处理协程
async def process_tasks():
    while True:
        task = await task_queue.get()
        try:
            task["status"] = "processing"
            
            # 执行批量处理
            # 实际实现中应调用批量处理函数
            task["total"] = 100  # 模拟总任务数
            for i in range(100):
                await asyncio.sleep(0.1)
                task["progress"] = i + 1
            
            task["status"] = "completed"
            task["result"] = f"{task['output_dir']}/results"
        except Exception as e:
            task["status"] = "failed"
            task["result"] = str(e)
        finally:
            task_queue.task_done()

2.4 健康检查接口

实现健康检查接口，便于Kubernetes监控：

@app.get("/health")
async def health_check():
    if model is None:
        return {"status": "unhealthy", "reason": "Model not loaded"}
    
    # 简单推理测试
    try:
        test_image = Image.new("RGB", (256, 256))
        # 实际实现中应进行简单推理测试
        return {"status": "healthy", "device": settings.device, "model": "FLUX.1-dev-ControlNet-Union"}
    except Exception as e:
        return {"status": "unhealthy", "reason": str(e)}

2.5 完整服务代码

          mountPath: /app/output
        livenessProbe:
          httpGet:
            path: /health
            port: 8000
          initialDelaySeconds: 300  # 模型加载时间较长，初始延迟设为5分钟
          periodSeconds: 30
        readinessProbe:
          httpGet:
            path: /health

          initialDelaySeconds: 60
          periodSeconds: 10
        startupProbe:
          httpGet:
            path: /health
            port: 8000
          failureThreshold: 30
          periodSeconds: 20
      volumes:
      - name: model-cache
        persistentVolumeClaim:
          claimName: model-cache-pvc
      - name: input-data
        persistentVolumeClaim:
          claimName: input-data-pvc
      - name: output-data
        persistentVolumeClaim:
          claimName: output-data-pvc

3.3 持久卷声明

创建持久卷声明，存储模型文件和数据：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: model-cache-pvc
  namespace: flux-controlnet
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 100Gi  # 模型文件较大，需要足够空间

---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: input-data-pvc
  namespace: flux-controlnet
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 50Gi

---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: output-data-pvc
  namespace: flux-controlnet
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 200Gi

3.4 服务配置

创建service.yaml文件，暴露推理服务：

apiVersion: v1
kind: Service
metadata:
  name: flux-controlnet-service
  namespace: flux-controlnet
spec:
  selector:
    app: flux-controlnet
  ports:
  - port: 80
    targetPort: 8000
  type: ClusterIP

3.5 入口配置

如果需要从集群外部访问，创建Ingress配置：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: flux-controlnet-ingress
  namespace: flux-controlnet
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
    nginx.ingress.kubernetes.io/proxy-body-size: "100m"  # 允许大文件上传
spec:
  rules:
  - host: flux-controlnet.example.com  # 替换为实际域名
    http:

          service:
            name: flux-controlnet-service
            port:
              number: 80

3.6 HPA配置

创建水平自动扩缩容配置：

apiVersion: autoscaling/v2
kind: HorizontalPodAutoscaler
metadata:
  name: flux-controlnet-hpa
  namespace: flux-controlnet
spec:
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: flux-controlnet-deployment
  minReplicas: 2
  maxReplicas: 10
  metrics:
  - type: Resource
    resource:
      name: cpu
      target:
        type: Utilization
        averageUtilization: 70
  - type: Resource
    resource:
      name: memory
      target:

kubectl apply -f hpa.yaml

# 可选：创建Ingress
# kubectl apply -f ingress.yaml

echo "Deployment completed. Checking status..."
kubectl get pods -n flux-controlnet
kubectl get svc -n flux-controlnet

第四章：性能优化与监控

4.1 模型推理优化

优化方法实现方式预期效果
混合精度推理使用torch.bfloat16减少显存占用30-50%
模型并行将模型拆分到多个GPU支持更大批次和更高分辨率
推理预热启动时进行几次小批量推理消除首推理延迟
请求批处理实现动态批处理提高GPU利用率20-40%
模型量化使用INT8量化减少显存占用50%，提速20%

实现混合精度推理：

# 修改模型加载代码
controlnet = FluxControlNetModel.from_pretrained(controlnet_model, torch_dtype=torch.bfloat16)
pipe = FluxControlNetPipeline.from_pretrained(base_model, controlnet=controlnet, torch_dtype=torch.bfloat16)
pipe.to("cuda")
pipe.enable_model_cpu_offload()  # 启用CPU卸载
pipe.enable_attention_slicing("max")  # 启用注意力切片

4.2 Prometheus监控配置

创建prometheus.yaml配置，监控服务性能：

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: flux-controlnet-monitor
  namespace: monitoring
  labels:
    release: prometheus
spec:
  selector:
    matchLabels:
      app: flux-controlnet
  namespaceSelector:
    matchNames:
    - flux-controlnet
  endpoints:
  - port: http
    path: /metrics
    interval: 15s

在FastAPI服务中添加Prometheus监控：

from prometheus_fastapi_instrumentator import Instrumentator, metrics

# 添加Prometheus监控
instrumentator = Instrumentator().instrument(app)

@app.on_event("startup")
async def startup_event():
    global model
    print(f"Loading model on {settings.device}...")
    model = FluxControlNetModel(json.load(open("config.json")))
    print("Model loaded successfully")
    
    # 启动监控
    instrumentator.expose(app, endpoint="/metrics")
    
    # 启动任务处理协程
    asyncio.create_task(process_tasks())

# 添加自定义指标
instrumentator.add(metrics.requests())
instrumentator.add(metrics.latency())
instrumentator.add(metrics.endpoint_requests())

# 添加推理相关指标
inference_counter = Counter('inference_requests_total', 'Total number of inference requests', ['control_mode', 'status'])
inference_duration = Histogram('inference_duration_seconds', 'Duration of inference requests', ['control_mode'])

# 在推理接口中使用指标
@app.post("/infer", response_class=FileResponse)
async def infer(...):
    inference_counter.labels(control_mode=control_mode, status="started").inc()
    with inference_duration.labels(control_mode=control_mode).time():
        # 推理代码
        ...
    inference_counter.labels(control_mode=control_mode, status="completed").inc()

4.3 Grafana仪表板
