and set `networkPolicy.enabled` to `true`.

For Kubernetes v1.5 & v1.6, you must also turn on NetworkPolicy by setting
the DefaultDeny namespace annotation. Note: this will enforce policy for *all* pods in the namespace:

```
kubectl annotate namespace default "net.beta.kubernetes.io/network-policy={\"ingress\":{\"isolation\":\"DefaultDeny\"}}"
```

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

**Note**: Make sure you put `"fastapi[standard]"` in quotes to ensure it works in all terminals.

## Example

### Create it

Create a file `main.py` with:

```Python
from fastapi import FastAPI

创建并激活一个 [虚拟环境](https://fastapi.tiangolo.com/zh/virtual-environments/)，然后安装 FastAPI：

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

**Note**: 请确保把 `"fastapi[standard]"` 用引号包起来，以保证在所有终端中都能正常工作。

## 示例 { #example }

### 创建 { #create-it }

创建文件 `main.py`，内容如下：

```Python
from fastapi import FastAPI

app = FastAPI()
