正如主题所说。我在主机清单文件中定义了一些主机变量。如何在我的剧本中访问它们?
这是一个例子。根据我的所有研究,我希望foo
和bar
成为hostvars
的一部分。我可以将主机特定变量放在单独的var文件中,但我希望将它们保存在我的库存文件“附加”到主机中。我不想在模板中使用它。
ansible版本:1.3.2,ansible_distribution_version:6.4
bash $
bash $ ansible --version
ansible 1.3.2
bash $
bash $ cat test_inv.ini
[foobar]
someHost foo="some string" bar=123
someOtherHost foo="some other string" bar=456
bash $
bash $ cat test.yml

答案 0 :(得分:17)
执行以下操作应该有效:
debug: msg="foo={{foo}}"
foo
变量将在当前主机的上下文中进行评估。使用ansible 1.3.4进行本地测试。
