2中出现重复的按键警告

本文介绍了防止Ansible 2中出现重复的按键警告的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我在角色中使用了许多YAML锚和引用,以将逻辑保持在一个位置,而不是在多个任务中重复自己.以下是一个非常非常基本的示例.

I use a lot of YAML anchors and references in my roles to keep the logic in a single spot instead of repeating myself in multiple tasks. Following is a very very basic example.

- &sometask
  name: "Some Task"
  some_module: with a lot of parameters
  with_items: list_A

- <<: *sometask
  name: "Some OTHER Task"
  with_items: list_B

因此,我没有对整个任务定义两次,而是对第一个使用锚,并将其所有内容合并到一个新任务中,然后覆盖不同的部分.很好.

So instead of defining the whole task twice, I use an anchor to the first one and merge all its content into a new task, then override the differing pieces. That works fine.

请清楚一点,这是基本的YAML功能,与Ansible本身无关.

Just to be clear, this is basic YAML functionality and has nothing to do with Ansible itself.

以上定义的结果(以及Ansible解析YAML文件时看到的内容)将评估为:

The result of above definition (and what Ansible sees when it parsed the YAML file) would evaluate to:

- name: "Some Task"
  some_module: with a lot of parameters
  with_items: list_A

- name: "Some Task"
  some_module: with a lot of parameters
  with_items: list_A
  name: "Some OTHER Task"
  with_items: list_B

Ansible 2现在具有一项功能,可以在任务中多次定义键时进行投诉.它仍然有效,但是在运行剧本时会产生不必要的噪音:

Ansible 2 now has a feature to complain when keys have been defined multiple times in a task. It still works, but creates unwanted noise when running the playbook:

TASK [Some OTHER Task] *******************************************************
 [WARNING]: While constructing a mapping from /some/file.yml, line 42, column 3, found a duplicate dict key (name).  Using last defined value only.

 [WARNING]: While constructing a mapping from /some/file.yml, line 42, column 3, found a duplicate dict key (with_items).  Using last defined value only.

Ansible配置可防止 deprecation_warnings command_warnings .有没有办法防止这种警告?

Ansible configuration allows to prevent deprecation_warnings and command_warnings. Is there a way to also prevent this kind of warning?

推荐答案

从Ansible 2.9.0开始,可以通过将 ANSIBLE_DUPLICATE_YAML_DICT_KEY 环境变量设置为 ignore 来实现..此变量的其他可能值是 warn (它是默认值并保留原始行为)和 error (这会使剧本执行失败).

As of Ansible 2.9.0, this can be achieved by setting the ANSIBLE_DUPLICATE_YAML_DICT_KEY environment variable to ignore. Other possible values for this variable are warn, which is the default and preserves the original behaviour, and error, which makes the playbook execution fail.
