Automate setup and delivery for virtual machines in the cloud
在云上自动化设置和交付虚拟机
======
Get a cloud image ready in minutes by using Testcloud to automate the
setup process and deliver a VM ready to run.
在几分钟之内准备好一个云镜像，通过使用 Testcloud 自动化设置过程并交付一个准备运行的虚拟机。
![Looking at a map][1]
If you're a developer or hobbyist using a Fedora [qcow2 image][2] for the cloud, you always have to do a bunch of initial configuration before an image is ready to use. I know this all too well, and I was eager to find a way to make the setup process simpler. As it happens, the entire Fedora quality assurance team feels the same way, so we developed [Testcloud][3].
如果你是一个在云上使用 Fedora [qcow2 镜像][2] 的开发者或者爱好者，在一个镜像准备使用之前，你总是不得不做一大堆初始化设置。我太清楚了，并且我渴望找到一种使设置过程更加简单的方法。碰巧，整个 Fedora 质量保证团队有同感，所以我们开发了 [Testcloud][3] 。
Testcloud is a tool that makes it easy to get a cloud image ready for testing in minutes. It automates the setup process and delivers a virtual machine (VM) ready to run on the cloud with just a few commands. 
Testcloud 是一个轻松的在几分钟之内准备云镜像测试的工具。它用几个命令在云上自动化设置并交付准备运行的虚拟机 (VM) 。
Testcloud:
1. Downloads the qcow2 image
2. Creates the instance with the name of your choice
3. Creates a user named `fedora` with the password of `passw0rd`
4. Assigns an IP, which you can later use to secure shell (SSH) into the cloud
5. Starts, stops, removes, and lists an instance
1. 下载 qcow2 镜像
2. 用你选择的名称创建实例
3. 创建一个密码为 `passw0rd` ，用户名为 `fedora` 的用户
4. 分配一个 IP 地址，以便于你之后用安全 shell (SSH) 登录到云上。
5. 启动， 停止，删除和列出一个实例

To start your journey, you first must install the Testcloud package. You can install it from a terminal or through the software application. In both cases, the package name is `testcloud`. Install with:
要开始你的过程，首先你必须安装 Testcloud 软件包。你可以通过终端或者软件程序来安装它。在这两种情况下，软件包的名字都是 `testcloud` 。用以下命令安装：
```
`$ sudo dnf install testcloud -y`
```
Once the installation is complete, add your desired user to the `testcloud` group, which helps Testcloud automate the rest of the process. Execute these two commands to add your user to the `testcloud` group and restart the session with the updated group privileges:
一旦安装完成，添加你要添加的用户到 `testcloud` 用户组，协助 Testcloud 完成设置过程的剩余部分。执行这两个命令添加你的用户到 `testcloud` 用户组，并通过提升组权限重启会话：

### Spin cloud images like a pro
Once your user has the required group permissions, create an instance:
### 像老手一样玩转云镜像
一旦你的用户获得了组权限，创建一个实例：
```
`$ testcloud instance create <instance name> -u <url for qcow2 image>`
```
Alternatively, you can use `fedora:latest/fedora:XX` (where `XX` is your Fedora release) instead of the full URL:
或者，你可以使用 `fedora:latest/fedora:XX` ( `XX` 是你的 Fedora 发行版本) 来代替 URL 完成地址：
```
`$ testcloud instance create <instance name> -u fedora:latest`
```
This returns the IP address of your VM:
这将返回你的 VM 的 IP 地址：
```
$ testcloud instance create testcloud272593 -u <https://download.fedoraproject.org/pub/fedora/linux/releases/33/Cloud/x86\_64/images/Fedora-Cloud-Base-33-1.2.x86\_64.qcow2>

```
You can log in as the default user `fedora` with the password `passw0rd` (note the zero). You can get to the VM with `ssh`, `virt-manager`, or any other method that supports connecting to libvirt machines.
Another simple way to create a Fedora cloud is:
你可以使用密码为 `passw0rd` (注意这个 0 ) 用户名为 `fedora` 的默认用户来登录。你可以使用 `ssh` 协议登录到 VM ，<ruby>`virt-manager`<rt>虚拟机管理器</rt></ruby> ，或者支持连接到 libvirt 虚拟机的其他方式。
另一种创建 Fedora 云的方式是：

Testcloud can be used to administer instances. This includes activities such as listing images or stopping and starting an instance.
Testcloud 可以用来管理实例。这包括像列出镜像或者停止和启动一个实例等活动。
