Question

我们目前在我们的环境中有这个命名约定

template <typename T, T ... Is>
constexpr T add (std::integer_sequence<T, Is...> const & a)
 { return ( Is + ... ); }

作为我的剧本的一部分，我有以下几乎打印abc.dev.example.com ## dev servers abc.staging.example.com ## staging servers abc.example.com ### prod servers

abc.dev.example.com

但是当我将env变量留空时，我得到以下vars: env: dev tasks: - name: show vars debug: msg=abc.{{env | default([])}}.example.com。我需要它abc..example.com。

知道如何在ansible中编写额外的abc.example.com字符吗？

你可以使你的条件显式而不是依赖于default（）

 debug: msg=abc.{% if thing is defined %}{{ thing }}.{% else %}{% endif %}example.com
