## Introduction

In ucloud **etcd** is the main storage backend. All ucloud components
need to be able to access etcd.!

## Base configuration

The main configuration is **/etc/ucloud/ucloud.json**.

```
{
  "etcd": {
    ...
  }
}
```

* The etcd
  object contains the host, port and other configurations. Lookup
  the [python-etcd3
  documentation](https://python-etcd3.readthedocs.io/en/latest/usage.html)
