## Get started

### 1. Prerequisites

- Docker 18.03 or above, refer here for [installation](https://docs.docker.com/install/).

### 2. Start etcd

etcd uses [gcr.io/etcd-development/etcd](https://console.cloud.google.com/gcr/images/etcd-development/GLOBAL/etcd) as a primary container registry.

```
rm -rf /tmp/etcd-data.tmp && mkdir -p /tmp/etcd-data.tmp && \

除了上述中间件外，FastAPI 还支持其它 ASGI 中间件。

例如：

* [Uvicorn 的 `ProxyHeadersMiddleware`](https://github.com/encode/uvicorn/blob/master/uvicorn/middleware/proxy_headers.py)
* [MessagePack](https://github.com/florimondmanca/msgpack-asgi)

being tested isn't intimately dependent on how Elasticsearch behaves as a
cluster, it is recommended to write unit tests or REST tests instead.

In short, most new functionality should come with unit tests, and optionally
REST tests to test integration.

==== Refactor code to make it easier to test

Unfortunately, a large part of our code base is still hard to unit test.
