你好

  • 我在Nutanix AOS上安装了Ubuntu 20.04 LTS，该安装用作模板
  • 此Ubuntu Tempate安装是一种基本的Ubuntu安装（单击基本安装，安装云）
  • 现在，我希望用户能够从此Ubuntu模板中部署新的VM作为克隆，并通过“自定义脚本”选项通过PRISM GUI中的云输入脚本。

不幸的是，这不起作用 - 创建克隆期间未应用“自定义脚本”云指令。

我是否必须在Ubuntu模板安装中修改某些内容（例如cloud-Init DataSource或Similiar，/etc/cloud/cloud.cfg或erthing）？

我看现有文档（云，nutanix，ubuntu）等的地方都不重要。

过去，我有一个工作示例，centos 7与nutanix，cloud -init和通过prism元素中的自定义脚本选项部署 - 但我无法与ubuntu一起运行它

P.S
我知道这篇文章https://portal.nutanix.com/page/documents/kbs/details?targetId=ka00e00000000000000cshjcas- 但这不是我需要的 - 我不想让创建VM的用户访问ACLI-他们只能在我的环境中通过Prism Element GUI工作，因此我必须使用上述Ubuntu模板的克隆过程来完成此操作。。

Ok, i got it - it was a pain in the ass and i\u2019m far away from having it finished for production but the part with Nutanix (Custom Script invokation in Clone Dialog) is solved.<\/p>

Steps that are necessary for Ubuntu 20.04 LTS (*if* you have a Ubuntu 20.04 Basic Installation which you have set up normally as a Guest and which you want to use as a Source for Clones and adjustement via cloud-init) :<\/p>

\u00a0<\/p>

  1. apt purge cloud-init (clean up Template Installation from existing cloud-init)<\/li>\t
  2. rm -rf \/etc\/cloud (clean up Template Installation from existing cloud-init)<\/li>\t
  3. rm -rf \/run\/cloud-init (clean up Template Installation from existing cloud-init)<\/li>\t
  4. apt install cloud-init (install cloud-init newly)<\/li>\t
  5. dpkg-reconfigure cloud-init (select ConfigDrive, None as Options)<\/li>\t
  6. systemctl enable cloud-init.service<\/li>\t
  7. shutdown Template VM (and use it as Source VM for Clone in Prism)<\/li>\t
  8. Clone the template VM via \u201cCustom Script\u201d option and pass your cloud-init user-data stuff<\/li><\/ol>

    \u00a0<\/p>

    This is the basic outline. Maybe there would be an easier way - i hate cloud-init<\/div>

嘿 @bgs，你检查了这篇文章吗https://next.nutanix.com/community-blog-154/customizing-vms-with-with-cloud-init-nutanix-on-nutanix-ahv-part-part-part-part-part-14573，也许这会有所帮助。

否则，我认为正如您所说，您可能必须在Ubuntu模板安装中修改一些内容，例如Cloud-Init DataSource或Similiar，/etc/cloud/cloud.cfg等给你。

谢谢。

这是一件烦人的事情。似乎与Ubunut Cloud-Init配置有关。我已经使用CentOS 7基础安装，安装Cloud-Init进行快速测试，然后通过“自定义脚本”选项将其克隆到Prism中。这是开箱即用的。

我已经通过不同的云进行了许多测试。

在Ubuntu 20.04下，您可以通过“ DPKG-RECONFIGURE CLOUD-INIT”轻松地将数据源从云中更改，然后选择“ nocloud”数据源..但是无法解决问题。

Thanks.<\/p>

It\u2019s an annoying thing. Seems to have to do with the Ubunut Cloud-init config. I have make a quick test with Centos 7 base install, install cloud-init and then cloning it in Prism via \u201cCustom Script\u201d option. This works out of the box.<\/p>

I\u2019ve made many tests with different cloud.cfg configurations with Ubuntu 20.04 - but no luck so far.<\/p>

Under Ubuntu 20.04 you can easily change datasource from cloud-init via \u201cdpkg-reconfigure cloud-init\u201d and select \u201cNoCloud\u201d datasource..but that doesnt solve the problem.<\/p>","quoteUsername":"BGS","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

好的，我明白了 - 这是屁股的痛苦，我离它完成生产很远，但是解决了Nutanix的零件（克隆对话框中的自定义脚本调用）。

Ubuntu 20.04 LTS所需的步骤（*如果**您有Ubuntu 20.04基本安装，您已正常设置为客人，并且您想用作克隆来源并通过云机构进行调整）：

  1. APT吹扫云机构（从现有云机构清理模板安装）
  2. RM -RF /ETC /Cloud（从现有云机构清理模板安装）
  3. RM -RF /RUN /CLOUD-INIT（从现有云中清理模板安装）
  4. APT安装Cloud-Init（新安装Cloud-Init）
  5. dpkg-reconfigure cloud-init（select configrive，无作为选项）
  6. systemctl启用云内部。服务
  7. 关闭模板VM（并将其用作棱镜中克隆的源VM）
  8. 通过“自定义脚本”选项克隆模板VM并传递您的Cloud-Init用户数据

这是基本大纲。也许会有一种更简单的方法 - 我讨厌云

嘿 @bgs很高兴您可以弄清楚。非常开心。：Sweat_smile：

顺便说一句，您是如何弄清楚的。：微笑：
