### 3.1 Use `certgen` to Generate a Certificate

Download [`certgen`](https://github.com/minio/certgen/releases/latest) for your specific operating system and platform.

`certgen` is a simple *Go* tool to generate self-signed certificates, and provides SAN certificates with DNS and IP entries:

```sh
./certgen -host "10.10.0.3,10.10.0.4,10.10.0.5"
```

## 範例升級

  file:// (which is highly likely to be the case), or the repository is
  not on a local filesystem, deployment will fail when offline.

** Testing mojos

  This can be a problem if the tests are more than simple unit tests;
  that is, if they require configuration of a server process, and
  subsequent testing in-container.

  Since we're only going to concern ourselves with states where localhost is

## Operation IDs personalizados y mejores nombres de métodos { #custom-operation-ids-and-better-method-names }

Puedes **modificar** la forma en que estos operation IDs son **generados** para hacerlos más simples y tener **nombres de métodos más simples** en los clientes.

En este caso tendrás que asegurarte de que cada operation ID sea **único** de alguna otra manera.
