Test Fedora 24 Beta in an OpenStack cloud
|
||||
===========================================
|
||||
|
||||
|
||||
|
||||
Although there are a few weeks remaining before [Fedora 24][1] is released, you can test out the Fedora 24 Beta release today! This is a great way to get [a sneak peek at new features][2] and help find bugs that still need a fix.
|
||||
|
||||
The [Fedora Cloud][3] image is available for download from your favorite [local mirror][4] or directly from [Fedora’s servers][5]. In this post, I’ll show you how to import this image into an OpenStack environment and begin testing Fedora 24 Beta.
|
||||
|
||||
One last thing: this is beta software. It has been reliable for me so far, but your experience may vary. I would recommend waiting for the final release before deploying any mission critical applications on it.
|
||||
|
||||
### Importing the image
|
||||
|
||||
The older glance client (version 1) allows you to import an image from a URL that is reachable from your OpenStack environment. This is helpful since my OpenStack cloud has a much faster connection to the internet (1 Gbps) than my home does (~ 20 mbps upload speed). However, the functionality to import from a URL was [removed in version 2 of the glance client][6]. The [OpenStackClient][7] doesn’t offer the feature either.
|
||||
|
||||
There are two options here:
|
||||
|
||||
- Install an older version of the glance client
|
||||
- Use Horizon (the web dashboard)
|
||||
|
||||
Getting an older version of glance client installed is challenging. The OpenStack requirements file for the liberty release [leaves the version of glance client without a maximum version cap][8] and it’s difficult to get all of the dependencies in order to make the older glance client work.
|
||||
|
||||
Let’s use Horizon instead so we can get back to the reason for the post.
|
||||
|
||||
### Adding an image in Horizon
|
||||
|
||||
Log into the Horizon panel and click Compute > Images. Click + Create Image at the top right of the page and a new window should appear. Add this information in the window:
|
||||
|
||||
- **Name**: Fedora 24 Cloud Beta
|
||||
- **Image Source**: Image Location
|
||||
- **Image Location**: http://mirrors.kernel.org/fedora/releases/test/24_Beta/CloudImages/x86_64/images/Fedora-Cloud-Base-24_Beta-1.6.x86_64.qcow2
|
||||
- **Format**: QCOW2 – QEMU Emulator
|
||||
- **Copy Data**: ensure the box is checked
|
||||
|
||||
When you’re finished, the window should look like this:
|
||||
|
||||
|
||||
|
||||
Click Create Image and the images listing should show Saving for a short period of time. Once it switches to Active, you’re ready to build an instance.
|
||||
|
||||
### Building the instance
|
||||
|
||||
Since we’re already in Horizon, we can finish out the build process there.
|
||||
|
||||
On the image listing page, find the row with the image we just uploaded and click Launch Instance on the right side. A new window will appear. The Image Name drop down should already have the Fedora 24 Beta image selected. From here, just choose an instance name, select a security group and keypair (on the Access & Security tab), and a network (on the Networking tab). Be sure to choose a flavor that has some available storage as well (m1.tiny is not enough).
|
||||
|
||||
Click Launch and wait for the instance to boot.
|
||||
|
||||
Once the instance build has finished, you can connect to the instance over ssh as the fedora user. If your [security group allows the connection][9] and your keypair was configured correctly, you should be inside your new Fedora 24 Beta instance!
|
||||
|
||||
Not sure what to do next? Here are some suggestions:
|
||||
|
||||
- Update all packages and reboot (to ensure that you are testing the latest updates)
|
||||
- Install some familiar applications and verify that they work properly
|
||||
- Test out your existing automation or configuration management tools
|
||||
- Open bug tickets!

在OpenStack云中测试Fedora 24 Beta
|
||||
===========================================
|
||||
|
||||
|
||||
|
||||
虽然离[Fedora 24][1]还有几周，你可以今天就测试Fedora 24 Beta了。这是一个[窥探新特性][2]的好机会，并且可以帮助找出仍需要修复的bug。
|
||||
|
||||
[Fedora Cloud][3]镜像可以从你最喜欢的[本地镜像][4]或者[Fedora的服务器][5]中下载。本篇文章我将向你展示如何将这个镜像导入Openstack环境并且测试Fedora 24 Beta。
|
||||
|
||||
最后说一下：这还是beta软件。目前对我来说是可靠的，但是你的体验可能会不同。我建议你等到正式版发布再在上面部署关键的应用。
|
||||
|
||||
### 导入镜像
|
||||
|
||||
旧版的glance客户端（版本1）允许你在Openstack环境中导入一个URL镜像。由于我Openstack云的连接速度（1 Gbps）比我家 (大约20 mbps上传速度)快，这个功能对我很有用。然而，从URL导入的功能[在glance v2中被移除了]。[OpenStackClient][7]也不支持这个功能。
|
||||
|
||||
现在由两个选择：
|
||||
|
||||
- 安装旧版的glance客户端
|
||||
- 使用 Horizon (网页面板)
|
||||
|
||||
获取旧版本的glance是有挑战性的。Openstack自由发布的需求文件[对glance客户端没有最高版本上限][8]，并且很难找到让旧版客户端工作的依赖文件。
|
||||
|
||||
让我们使用Horizon，来回到写这篇文章的原因。
|
||||
|
||||
|
||||
### 在Horizon中添加一个镜像
|
||||
|
||||
登录Horizon面板，点击Compute->Image. 点击页面右上方的“+”创建新镜像，一个新的窗口会显示出来。并且窗口中有这些信息：
|
||||
|
||||
- **Name**: Fedora 24 Cloud Beta
|
||||
- **Image Source**: Image位置
|
||||
- **Image Location**: http://mirrors.kernel.org/fedora/releases/test/24_Beta/CloudImages/x86_64/images/Fedora-Cloud-Base-24_Beta-1.6.x86_64.qcow2
|
||||
- **Format**: QCOW2 – QEMU Emulator
|
||||
- **Copy Data**: 确保勾选了
|
||||
|
||||
完成后，你会看到这个：
|
||||
|
||||
|
||||
|
||||
点击创建镜像，接着会显示一段时间的Saving。一旦切换到Active，你可以构建一个实例了。
|
||||
|
||||
### 构建实例
|
||||
|
||||
既然我们在Horizon，我们可以完成构建过程了。
|
||||
|
||||
在镜像列表页面，找出我们上传的镜像并且点击右边的启动实例。一个新的窗口会显示出来。下拉框中应该已经选择了Fedora 24 Beta的镜像。在这里，选择一个实例名，选择一个安全组和密钥对（在Access & Security中）和网络（在Networking标签）。确保选择有足够容量的存储（m1.tiny还不够）。
|
||||
|
||||
点击启动并且等待实例启动。
|
||||
|
||||
一旦实例构建完成，你可以作为fedora用户通过ssh连接。如果你的[安全组允许连接][9]并且你的密钥对正确配置了，你应该在Fedora 24 Beta中了！
|
||||
|
||||
还不确定接下来做什么？有下面几点建议：
|
||||
|
||||
- 升级所有的包并且重启（确保你测试的是最新的更新）
|
||||
- 安装一些相似的应用并且验证它们可以正常工作
|
||||
- 测试你已有的自动化或者配置管理工具
|
||||
- 打开bug报告
|
||||
