我知道在平静下您可以在服务中创建变量，然后在整个配置中使用@@ {service.variable} @@使用这些变量。但是，似乎您可以使用云脚本中的那些。我希望能够传递用户在部署时设置的变量（IP地址），然后将其在Cloud-Init脚本中使用。

我尝试了这样的事情，无济于事：

代码： 
＃Cloud-Config
主机名：haproxy1
fqdn：haproxy1.domain.com
SSH_PWAUTH：是的
write_files：
- 路径：/etc/sysconfig/network-scripts/ifcfg-eth0
内容：|
设备= ETH0
bootproto =“无”
ipaddr =“ @@ {haproxy1.ip_address} @@”
前缀=“ 24”
网关=“ 172.25.51.254”
domain =“ vipcustomers.com vtinfo.com”
defroute =“是”
onboot =“是”
DNS1 =“ 172.25.51.10”
dns2 =“ 172.25.51.2”
ipv4_failure_fatal =“是”
ipv6init =“否”
runcmd：
-  [ifdown，eth0]
-  [ifup，eth0]


其中haproxy1.ip_address是用户定义的变量。关于我如何实现这一目标有什么想法吗？

你好，

它应该起作用。我从Kubernetes蓝图中发现了这个片段，我几次使用了。您可以指定您正在使用的版本吗？PC，AOS，AHV/VMware等？

此致，
托马斯

\r\n
\r\nit should work. I found this snippet from the Kubernetes blueprint which I used several times. Could you specify which versions you are using? PC, AOS, AHV\/VMware etc.?

感谢回复 @tfindelk。我正在使用PC 5.5.2，AOS 5.5.0.6（下周升级到5.5.2）和AHV 20170830.94。

MHH ..用户定义的变量包含一个“”。点。也许您可以解释为什么这是？我定义的变量没有点。

@joelemaire我已经在5.7.0.1 PC上测试了您的蓝图，并且变量正常。在您的5.5.2版本上，您是否看到已部署VM，但未能设置IP地址或VM部署失败而失败？
@JoeLemaire<\/user-mention> I have tested your blueprint on 5.7.0.1 PC and the variable works fine.

@joelemaire在低于5.7 @@ {service.variable} @@的PC版本上，由于错误，@@在访客自定义脚本中不工作。作为替代方案，您可以在应用程序配置文件中定义变量，并在云初始脚本中使用它。下面的说明用于配置应用程序配置文件中的变量，

https://portal.nutanix.com/#/page/docs/details?targetID=Nutanix-calm-admin-operations-guide-v57:nuc-adding-configure-application-profile-profile-profile-t.html

您应该在蓝图中已经有一个默认的应用程序配置文件，可以在默认应用程序配置文件中配置变量。

当您在应用程序配置文件中定义变量时，您只需将变量称为@@ {variable} @@在脚本中。因此，在您的情况下，如果您的变量为ip_address，则只需在CloudInit脚本中参考@@ {ip_address} @@。

@chandru感谢您的提示。实际上，这最终解决了我的问题！

出于好奇心，是否有好处（围绕此错误工作）来定义应用程序配置文件与服务本身中的变量？它是一种更好的方式还是另一种方式？只是为“最佳实践”感到好奇。

另外，谢谢 @tfindelk为此，您的协助也是如此！
@Chandru<\/user-mention> thanks for the tip here. That actually ended up fixing my issue!
\r\n
\r\nOut of curiosity, is there a benefit (outside of working around this bug) to defining the variable in the Application Profile vs the service itself? Is it better one way or the other? Just curious for the 'best practice'.
\r\n

@joelemaire取决于用例等，将其视为在蓝图中对象上变量的范围。因此，根据您想要使用的位置等，您可能需要在其他级别上定义它。
@JoeLemaire<\/user-mention> Depends on the use case etc, think of it as scoping for the variable on the objects in the blueprint. SO depending on where you want to use it etc, you might want to define it at a different level.","quoteUsername":"Jasnoor.Gill","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
