How specify a list value as variable in ansible inventory file?
提问by rmuller
I need something like (ansible inventory file):
我需要类似的东西（ansible库存文件）：
[example]
127.0.0.1 timezone="Europe/Amsterdam" locales="en_US","nl_NL"
However, ansible does not recognize 'locales' as a list.
但是，ansible 不会将“语言环境”识别为列表。

You can pass a list or object like this:
您可以像这样传递列表或对象：
[example]
127.0.0.1 timezone="Europe/Amsterdam" locales='["en_US", "nl_NL"]'
回答by Lorin Hochstein
With complex variables, it's best to define them in a host_vars file rather than in the inventory file, since host_vars files support YAML syntax.
对于复杂变量，最好在 host_vars 文件中而不是在清单文件中定义它们，因为 host_vars 文件支持 YAML 语法。
Try creating a host_vars/127.0.0.1file with the following content:
尝试创建一个host_vars/127.0.0.1包含以下内容的文件：
timezone: Europe/Amsterdam
locales:
- en_US
- nl_NL

Ryler's answer is good in this specific case but I ran into problems using other variations with the template module.
在这种特定情况下，Ryler 的回答很好，但我在使用模板模块的其他变体时遇到了问题。
[example]
127.0.0.1 timezone="Europe/Amsterdam" locales='["en_US", "nl_NL"]'
Is his original example and works fine.
是他的原始示例并且工作正常。
The following variations work with template. Basically if it's a string you must remember to use the internal double quotes or the entire structure is parsed as a single string. If it's only numbers or "True" or "False" (not "yes") then you're fine. In this variation I couldn't make it work with template if it had external quotes.
以下变体适用于模板。基本上，如果它是一个字符串，您必须记住使用内部双引号或整个结构被解析为单个字符串。如果它只是数字或“真”或“假”（不是“是”），那么你没问题。在这个变体中，如果它有外部引号，我就不能让它与模板一起工作。
I haven't done an exhaustive check of which internal use cases they do and do not break other than the template module.
除了模板模块之外，我还没有对它们执行哪些内部用例并且不破坏哪些内部用例进行详尽的检查。
I am using Ansible 2.2.1.
我正在使用 Ansible 2.2.1。
[example:vars]
# these work
myvar1=["foo", "bar"]
myvar2=[1,2]
myvar3=[True,False]
# These fail, they get interpreted as a single string.
myvar4=[yes, no]
myvar5=[foo,bar]
myvar6='["foo", "bar"]'

you can try split
你可以尝试拆分
#inventory file
[example]
127.0.0.1 timezone="Europe/Amsterdam" locales="en_US","nl_NL"
#role file
---
- debug: msg="{{ item }}"
with_items: locales.split(',')

You can custom a filter, to split string to list
您可以自定义过滤器，将字符串拆分为列表
Github ansible exampleshow how to create custom filter.
Github ansible 示例展示了如何创建自定义过滤器。
