暂时替换include的变量

Question

我有这样的任务：

- include: tasks/install_nginx_vhost.yml
  vars:
    domain_name: learn.{{ domain_name }}

- include: tasks/install_nginx_vhost.yml
  vars:
    domain_name: author.{{ domain_name }}

但是我收到了这个错误：

recursive loop detected in template string

是否可以暂时（仅限于include）覆盖这样的变量？因为我不想创建其他变量。

Answer 1

不是。

- set_fact:
    learn_domain_name:  "learn.{{ domain_name }}"
    author_domain_name: "author.{{ domain_name }}"

- include: tasks/install_nginx_vhost.yml
  vars:
    domain_name: "{{ learn_domain_name }}"

- include: tasks/install_nginx_vhost.yml
  vars:
    domain_name: "{{ author_domain_name }}"

或更可取，如果可能，您可以将原始domain_name说明重命名为domain_name_suffix。然后：

- include: tasks/install_nginx_vhost.yml
  vars:
    domain_name: learn.{{ domain_name_suffix }}

- include: tasks/install_nginx_vhost.yml
  vars:
    domain_name: author.{{ domain_name_suffix }}
