Ansible模板在破折号后跳过字符串 [英] Ansible templating skips string after a dash

问题描述

我正在用Ansible来模板化带有一组变量的文件.

I am templating a file with a set of variables in Ansible.

我的defaults/main.yaml文件中的一些条目是:

A few entries in my defaults/main.yaml file are :

jenkins_plugins:
  'ant': '1.8'
  'antisamy-markup-formatter': '1.5'
  'apache-httpcomponents-client-4-api': '4.5.3-2.1'
  'kubernetes': '1.3'

此键值对之一应该在我的模板文件config.xml.j2的此行中注入:

One of this key-value pair is supposed to be injected in this line in my template file config.xml.j2 :

<markupFormatter class="hudson.markup.RawHtmlMarkupFormatter" plugin="antisamy-markup-formatter@{{ jenkins_plugins.antisamy-markup-formatter }}">

所以基本上我的最终结果应该是:

So basically my end result should look like :

<markupFormatter class="hudson.markup.RawHtmlMarkupFormatter" plugin="antisamy-markup-formatter@1.5">

但是，当我运行调用此模板文件的剧本时，会收到错误消息:

But when I run the playbook that calls this templating file, I get the ERROR :

TASK [jenkins : Generate config.xml file.] ****************************************
fatal: [default]: FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: 'dict object' has no attribute 'antisamy'"}

如果我删除所有破折号-，它将正常工作，但这是我无法做的事情，因为我还必须下载这些插件，并且需要用破折号来修饰正确的名称.

If I remove all the dashes -, it will work fine but that is something I cannot do since I also have to download these plugins and I need to curl on the correct names with dashes.

神社为什么打算跳过-之后的所有内容?

Why is the jinja templating skipping everything after - ?

推荐答案

Python在属性名称中不喜欢破折号-，但是您可以使用地图语法:

Python doesn't like dashes - in attribute names, but you can use the map syntax:

{{ jenkins_plugins["antisamy-markup-formatter"] }}

如果您的变量名中包含破折号，则可以使用vars:

If you have VARIABLE NAMES that contain a dash, you can use vars:

{{ vars["jenkins-plugins"] }}

但是，请注意，如果尝试定义包含破折号的变量，则ansible将引发错误，指出变量名称不能包含破折号.这仅在使用默认值"时有效-但我想这是一个错误.

However, be aware that if you try to define a variable that contains a dash, ansible will throw an error saying that variable names cannot contain dashes. This only works when using "defaults" - but I guess it's a bug.
