如何让“yes”不被评估为布尔值

Question

以下是任务：

        - name: set value
          set_fact:
            is_enabled: 'yes'

        - name: debug is_enabled value
          debug:
            var: is_enabled

这会将值打印为“true”而不是“yes”。我尝试将类型转换为字符串。还尝试过：

        - name: set value
          set_fact:
            is_enabled: >
              yes

        - name: debug is_enabled value
          debug:
            var: is_enabled

这将打印“yes/n”。

有什么方法可以将变量值设置为“YES”。

Answer 1

正如有关 Ansible Issue #12519 的评论中提到的那样，它似乎是 YAML 的语言功能。根据Ansible set_fact类型转换可以设置DEFAULT_JINJA2_NATIVE

---
- hosts: localhost
  become: false
  gather_facts: false

  vars:

    yes1: yes
    yes2: 'yes'
    yes3: "yes"

  tasks:

  - name: Set yes
    set_fact:
      yes4: 'yes'
      yes5: "yes"

  - name: Show values
    debug:
      msg: |
        yes1 is {{ yes1 | type_debug }} and has value {{ yes1 }}
        yes2 is {{ yes2 | type_debug }} and has value {{ yes2 }}
        yes3 is {{ yes3 | type_debug }} and has value {{ yes3 }}
        yes4 is {{ yes4 | type_debug }} and has value {{ yes4 }}
        yes5 is {{ yes5 | type_debug }} and has value {{ yes5 }}

产生

的输出

ANSIBLE_JINJA2_NATIVE=True ansible-playbook set_yes_string.yml
[WARNING]: jinja2_native requires Jinja 2.10 and above. Version detected: 2.7.2. Falling back to default.
...
TASK [Show values] *************************
ok: [localhost] =>
  msg: |-
    yes1 is bool and has value True
    yes2 is AnsibleUnicode and has value yes
    yes3 is AnsibleUnicode and has value yes
    yes4 is AnsibleUnicode and has value yes
    yes5 is AnsibleUnicode and has value yes

此外，仅将

bool 设置为 string 过滤器是行不通的。

Answer 2

我解决这个问题的方法是用空格声明它，然后将其删除。

• 名称：设定值 设置事实： is_enabled=" {{ '是' }} "

• 名称：调试 is_enabled 值 调试： 消息：“{{ is_enabled | regex_replace(" ","") }}"
