### Створіть { #create-it }

Створіть файл `main.py` з:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: str | None = None):
    return {"item_id": item_id, "q": q}
```

⛔️ **Shell** form:

```Dockerfile
# ⛔️ Don't do this
CMD fastapi run app/main.py --port 80
```

FastAPI'nin düzgün şekilde kapanabilmesi ve [lifespan event](../advanced/events.md)'lerinin tetiklenmesi için her zaman **exec** formunu kullanın.

Detaylar için [shell ve exec form için Docker dokümanlarına](https://docs.docker.com/reference/dockerfile/#shell-and-exec-form) bakabilirsiniz.

```Dockerfile
# ✅ 推荐
CMD ["fastapi", "run", "app/main.py", "--port", "80"]
```

⛔️ **Shell** 形式：

```Dockerfile
# ⛔️ 不要这样
CMD fastapi run app/main.py --port 80
```

务必使用**exec** 形式，以确保 FastAPI 可以优雅停机并触发[生命周期事件](../advanced/events.md)。

你可以在 [Docker 文档（Shell 与 Exec 形式）](https://docs.docker.com/reference/dockerfile/#shell-and-exec-form)中了解更多。

#### **4.2.1 Upload the input file to HDFS:**

```
hadoop fs -copyFromLocal /etc/hadoop/conf/log4j.properties
          s3a://testbucket/testdata
```

#### **4.2.2  Run the Spark shell:**

```
./bin/spark-shell --master yarn-client --driver-memory 512m --executor-memory 512m
```

The command should produce an output as shown below. (with additional status messages):

```

{* ../../docs_src/custom_response/tutorial009c_py310.py hl[9:14,17] *}

Artık şunu döndürmek yerine:

```json
{"message": "Hello World"}
```

...bu response şunu döndürür:

```json
{
  "message": "Hello World"
}
```

Elbette JSON’u formatlamaktan çok daha iyi şekillerde bundan faydalanabilirsiniz. 😉
