有人能解释 Ansible 中的以下 Jinja 行为吗？
以下代码有效：跳过该任务，因为 job_function 不在 rejection_functions 数组中
- name: Lowercase test
hosts: localhost
gather_facts: false
vars:
job_function: 'VRIJwillig'
exclusion_functions:
- vrijwilliger
- maatje
tasks:
- name: Test for function in exclusions
debug:
msg: In exclusions
when: (job_function | lower) in exclusion_functions
以下代码同样有效，第二个任务被跳过。
- name: Lowercase test
hosts: localhost
gather_facts: false
vars:
job_function: 'VRIJwillig'
exclusion_functions:
- Vrijwilliger
- Maatje
tasks:
- name: Initialiseer variabelen
set_fact:
exclusions: "{{ exclusion_functions | lower }}"
- name: Test for function in exclusions
debug:
msg: In exclusions
when: (job_function | lower) in exclusions
但这不起作用，任务没有被跳过：
---
- name: Lowercase test
hosts: localhost
gather_facts: false
vars:
job_function: 'VRIJwillig'
exclusion_functions:
- Vrijwilliger
- Maatje
tasks:
- name: Test for function in exclusions
debug:
msg: In exclusions
when: (job_function | lower) in (exclusion_functions | lower)
为什么在最后一段代码中没有跳过任务？job_function | lower是vrijwillig，并且exclusion_functions | lower是['vrijwilliger','maatje']，而第一个不在第二个中。
