Jinja2 Filter - 仅在文件更改时过滤和输出结果

Question

我正在使用 Ansible Core，我只想在命令行中更改任务时应用过滤器

这是我的 playbook.yml

---
- name: Global Objects
  hosts: check_point
  connection: httpapi
  gather_facts: False
  vars_files:
    - 'credentials/my_var.yml'
    - 'credentials/login.yml'

  tasks:
  - name:  read-csv-file
    read_csv:
      path: file_reader/Networks.csv
      key: Name
    register: user
    
  - set_fact:
      hosts_in_group: "{{ user.dict | dict2items | map(attribute='key') | list }}"

  - name: add-host-object
    check_point.mgmt.cp_mgmt_host:                    
      name: "{{ item.value.Name | quote }}"          
      ip_address: "{{ item.value.IP | quote }}"      
      comments: "{{ item.value.Comments }}"           
      state: present
    loop: "{{ user.dict | dict2items }}"               
    ignore_errors: yes
    delegate_to: Global
    register: servers_changed_now



  - set_fact:
      new_list: "{{ servers_changed_now.results }}"
    register: new_result
  - debug:
      msg: "{{ new_result }}"

这是我要过滤的输出

gTest103,10.1.2.4,FWP - Applying this
gTest104,10.1.2.5,FWP - Ansible

当我运行代码时，gTest104和gTest101变了，gTest103失败了 我只想获得 gTest104 和 gTest101 的结果，因为这是 更改的唯一任务 。
逻辑是当 changed: true 和 failed: false - 它改变了一个任务，但是当 changed: false and failed: true - 任务失败

问题：如何在 Ansible 中使用 Jinja2 Filter 来仅获取已更改的结果并将其仅显示到 ansible 中的控制台？

Answer 1

如果您尝试过滤并显示已更改但未失败的任务，这应该可行。

    - name: filter results
      set_fact:
        filtered_results: "{{ filtered_results|default([]) + [item] }}"
      with_items:
        - "{{ servers_changed_now.results }}"
      when:
        - item.changed == true
        - item.failed == false

    - name: display filtered result
      debug:
        msg: "{{ filtered_results }}"

when 可以更改条件以提取不同的结果。
