在become_user中使用变量时出现Ansible语法错误

Question

我正在使用Ansible 2.0.1.0。

在我的main.yml我有这个任务：

- name: hoge
  hosts: hoge2
  connection: docker
  become: yes
  become_user: {{ansible_user}}

执行时，我收到以下错误消息：

ERROR! Syntax Error while loading YAML.

The error appears to have been in '/Users/fuga/Docker/ansible/main.yml': line 16, column 17, but maybe elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

  become: yes
  become_user: {{ansible_user}}
                ^ here

如何解决错误？

Answer 1

在YAML中，{启动字典。因此，您需要引用表达式。

become_user: "{{ansible_user}}"

请参阅Gotchas in the Ansible YAML docs。
