Ansible回调插件:如何获取扩展了任务的任务名称? [英] Ansible callback plugin: how to get a task name with variables in it expanded?

问题描述

下面有一个剧本，其中包含一个任务，该任务的名称中包含变量.

I have a play below that contains a task with a name that has a variable in it.

hosts:        localhost
connection:   local
vars:
  a_variable: test
tasks:
  - name:     this is a task to echo {{ a_variable }}
    shell:    echo {{ a_variable }}

在命令行上运行此命令时，stdout将显示任务名称，其中变量已解析/扩展为其值，即this is a task to echo test

When this is run on the command line, the stdout shows the task name with variable resolved/expanded to its value which is this is a task to echo test

但是，当我尝试使用属性task.name或result._task.name访问回调插件中的任务名称时，返回的名称是this is a task to echo {{ a_variable }}变量未展开.

However, when I try to access the task name in the callback plugin using the properties task.name or result._task.name, the name returned is this is a task to echo {{ a_variable }} where the variable is not expanded.

我如何获得任务名称，因为它是在标准输出上打印并带有扩展变量的?

How can I get the task name as it is printed on stdout with the variable expanded?

推荐答案

模板化的任务名称仅在v2_playbook_on_task_start内部可用.

Templated task name is only available inside v2_playbook_on_task_start.

如果要在其他方法中使用模板化名称，则应创建插件范围的列表/字典，在v2_playbook_on_task_start期间填充任务名称，并在以后根据需要获取.

If you want to use templated name in other methods, you should create plugin-wide list/dict, populate tasks' names during v2_playbook_on_task_start and fetch it later, when needed.

最简单的方法是使用task._uuid作为参考(请参见

The simplest way to accomplish this is to use task._uuid as reference (see profile_tasks plugin as example.
