如何在一个烦人的任务中获取当前角色名称 [英] How to get current role name in an ansible task

问题描述

如何在ansible任务yaml文件中获取当前角色名称?

How can I get the current role name in an ansible task yaml file?

我想做这样的事情

---
# role/some-role-name/tasks/main.yml

- name: Create a directory which is called like the current role name
  action: file
          path=/tmp/"{{ role_name }}"
          mode=0755
          state=directory

此任务的结果应该是服务器上的目录/tmp/some-role-name

The result of this task should be a directory /tmp/some-role-name on the server

推荐答案

从 Ansible 2.2开始:

{{role_name}}

截至 Ansible 2.1 :

{{role_path|basename}}

旧版本:

在当前版本的Ansible中无法执行此操作，以下是一些可能更适合您的选项:

There is no way to do this in the current version of Ansible, here are a couple options that might work for you instead:

1)使用set_fact将role_name var设置为您的task/main.yml文件中第一个任务的角色名称

1) Use set_fact to set a role_name var to the name the of role as the first task in your tasks/main.yml file

- set_fact: role_name=some-role-name

2)将名称传递给您的角色

2) Pass a parameter to your role that has the name

- roles:
  - role: some-role-name
    role_name: some-role-name
