这段代码看起来是一个使用FastAPI框架构建的Web应用程序。如果您需要对代码进行修改，可以按照您的需求进行更改。以下是一些建议的修改：

1. 导入所需的模块：确保您已经安装了所需的库，例如`fastapi`，`jinja2`等，并在代码的顶部导入它们。

from fastapi import FastAPI, Request, Form
from fastapi.responses import HTMLResponse
from fastapi.staticfiles import StaticFiles
from fastapi.templating import Jinja2Templates

2. 创建FastAPI实例：根据您的应用程序需求，可以在创建FastAPI实例时添加一些参数，例如标题和描述。

app = FastAPI(title="My App", description="A simple web application")

3. 配置静态文件和模板目录：确保您的静态文件和模板文件位于正确的目录，并在应用程序中进行正确的配置。

app.mount("/static", StaticFiles(directory="static"), name="static")
templates = Jinja2Templates(directory="templates")

4. 定义路由处理函数：根据您的应用程序需求，可以修改路由的路径和处理函数的逻辑。

@app.get("/", response_class=HTMLResponse)
async def index(request: Request):
    return templates.TemplateResponse("index.html", {"request": request, "containers": containers})

@app.post("/add_container")
async def add_container(request: Request, name: str = Form(...), image: str = Form(...)):
    container = {"name": name, "image": image}
    containers.append(container)
    return templates.TemplateResponse("index.html", {"request": request, "containers": containers})

@app.get("/delete_container/{index}")
async def delete_container(request: Request, index: int):
    containers.pop(index)
    return templates.TemplateResponse("index.html", {"request": request, "containers": containers})

@app.post("/update_container/{index}")
async def update_container(request: Request, index: int, name: str = Form(...), image: str = Form(...)):
    container = {"name": name, "image": image}
    containers[index] = container
    return templates.TemplateResponse("index.html", {"request": request, "containers": containers})

请注意，这只是一些建议的修改，具体的修改取决于您的需求和应用程序的逻辑。希望这能帮到您！
