ansible 剧本中特定情况下管道运算符的含义

Question

在 ansible 剧本的下面块中，| pipe 运算符后跟 bool 的含义是什么？
我分别理解它们的意思，但在这里对我来说似乎没有任何意义。为什么需要将 bool 解释为多行值？

The pipe symbol at the end of a line in YAML signifies that any indented text that follows should be interpreted as a multi-line scalar value. See the YAML spec.

- name: Remove default nginx vhost config file (if configured).
  file:
    path: "{{ nginx_default_vhost_path }}"
    state: absent
  when: nginx_remove_default_vhost | bool
  notify: restart nginx

Answer 1

它只是强制类型为 bool。

这里是关于它的文档https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html#forcing-the-data-type
