问题描述
我今天遇到了一个奇怪的情况.我在剧本environment 中调用了我的一个变量.如果我使用 debug 指令转储变量，则显示正常
I've got a strange situation today. I called one of my variables in a playbook environment. If I dump variables using debug instruction, it is shown ok
"environment": "development",
但是如果我尝试使用 {{ environment }} 从脚本访问它，它总是被分配一个 {} 的值.我重命名了它，它工作正常.这是为什么?environment 是 Ansible 中的保留名称吗?我检查了变量转储 - 与定义的变量没有冲突.
But if I try to access it from a script using {{ environment }} it is always assigned a value of {}. I renamed it and it worked ok. Why is that? Is environment a reserved name in Ansible? I checked variable dump - there is no clashes with defined vars.
推荐答案
我在 :
I found a statement regarding environment in the Google group:
是的，environment 是一个受限制的关键字.最初具体在剧本，但它被注入到跑步者中:
inject['environment'] = self.environment
所以它会清除变量清单设置的任何值.
so it will erase whatever value was set by inventory of vars.
有一个尚未解决的功能请求用于警告是否使用了保留变量.
There is a yet unaddressed feature request to warn if reserved variables are used.
