Question

将其放入group_vars/all：

default_environment:
  HOME2: "{{ ansible_env.HOME }}"

在任务中使用来定义环境时：

environment:
  "{{ default_environment }}"

我明白了：

The field 'environment' has an invalid value, which includes an undefined variable. The error was: {u'HOME2': u'{{ ansible_env.HOME }}'}: 'ansible_env' is undefined
exception type: <class 'ansible.errors.AnsibleUndefinedVariable'>

有没有办法根据当前的远程环境变量定义组变量，在这种情况下为$HOME？

编辑：每个请求，可重现的案例：

test.yml

- name: Test
  hosts: hosts1
  become: true
  become_user: user1

  environment:
    "{{ default_environment }}"

  tasks:
    - debug:
        msg: "{{ ansible_env }}"

group_vars /所有

default_environment:
  HOME2: "{{ ansible_env.HOME }}"

使用ansible-plyabook test.yml

运行时

输出

PLAY [Test] ********************************************************************************************************************************************************************************************************************************


TASK [Gathering Facts] *********************************************************************************************************************************************************************************************************************

fatal: [host1]: FAILED! => {}

MSG:

The field 'environment' has an invalid value, which includes an undefined variable. The error was: {u'HOME2': u'{{ ansible_env.HOME }}'}: 'ansible_env' is undefined
exception type: <class 'ansible.errors.AnsibleUndefinedVariable'>
exception: {u'HOME2': u'{{ ansible_env.HOME }}'}: 'ansible_env' is undefined

        to retry, use: --limit @/work/ansible/test.retry

错误消息是：

＆＃39; ansible_env＆＃39;未定义

你没有收集事实。

在您尝试收集事实之前运行游戏，而不声明environment：

- name: Test
  hosts: hosts1
  become: true
  become_user: user1

- name: Test
  hosts: hosts1
  become: true
  become_user: user1
  gather_facts: false

  environment:
    "{{ default_environment }}"

  tasks:
    - debug:
        msg: "{{ ansible_env }}"

Ansible group_vars环境变量替换
