背景:
这是使用模板从模板构造yaml文件的Ansible剧本。所以基本上我有一个带有这样一行的jinja2模板文件:
private_key: {{ myvar }}
Ansible使用yaml定义变量。因此，我将像这样填写
myvar值。在这里，我使用|特殊字符来定义多行字符串:myvar: |
- "-----BEGIN PRIVATE KEY-----"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "zzzzzzzzzzzzzzzzzz="
- "-----END PRIVATE KEY-----"
但是输出会缩进缩进:
private_key:
- "-----BEGIN PRIVATE KEY-----"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "zzzzzzzzzzzzzzzzzz="
- "-----END PRIVATE KEY-----"
由于输出文件本身是Yaml，因此我需要保留缩进。看来无论如何我都会缩进。
I need the end result to look EXACTLY like this:
private_key:
- "-----BEGIN PRIVATE KEY-----"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "zzzzzzzzzzzzzzzzzz="
- "-----END PRIVATE KEY-----"
最佳答案
发布问题后，我立即在Google搜索中找到了答案。
本质上，yaml字符串将去除缩进，因此在这种情况下，我们必须使用Jinja在要去除它们的位置插入空格。幸运的是，这很容易做到:
在模板文件中，我将其替换为:
private_key: {{ myvar }}
有了这个:
private_key: {{ myvar | indent( width=4, indentfirst=True) }}
width字段可以调整为需要多少个缩进空间。实际的变量声明与我在问题中发布的完全一样。但是，现在在模板中添加了缩进后，我现在有了带有缩进的所需输出:
private_key:
- "-----BEGIN PRIVATE KEY-----"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "asdfasdfasdfasdfasdfasdfadfasdfasdfasdfasdfasdfssadf"
- "zzzzzzzzzzzzzzzzzz="
- "-----END PRIVATE KEY-----"
