Question

我有两个事实，一个看起来像这样：

"ansible_facts": "int_table" {
    "[{ "connection": "notconnected",
        "port": "eth1"},
      { "connection": "connected",
        "port": "eth2"}]"

和

"ansible_facts": "mac_table" {
    "[{ "mac_address": "0000.c200.0101",
        "port": "eth1"},
      { "mac_address": "0320.c500.0201",
        "port": "eth2"}]"

我想创建一个新的事实，将它们的端口组合在一起，以便输出

"ansible_facts": "new_table" {
    "[{ "mac_address": "0000.c200.0101",
        "connection": "notconnected",
        "port": "eth1"},
      { "mac_address": "0320.c500.0201",
        "connection": "connected",
        "port": "eth2"}]"

这是否有可能做到？我尝试将两者都传递给自定义过滤器，以使用python将两者结合起来，但似乎无法将两个事实传递给同一过滤器。

操作方法如下：

从1个变量获取端口列表，例如int_table，它们应该是唯一的端口（即，每个列表中只有一个元素可以具有eth1，eth2等）
对于每个端口，从int_table中查找元素，并将其与mac_table中的相应元素组合
打印最终列表变量

剧本：

---
- hosts: localhost
  gather_facts: false
  vars:
    int_table:
    - connection: notconnected
      port: eth1
    - connection: connected
      port: eth2
    mac_table:
    - mac_address: 0000.c200.0101
      port: eth1
    - mac_address: 0320.c500.0201
      port: eth2


  tasks:

  - name: populate merged list
    set_fact: 
      final_var: "{{ final_var | default([]) + [int_table | selectattr('port','equalto', item) | first | combine(mac_table | selectattr('port','equalto', item) | first)] }}"
    with_items: 
    - "{{ int_table | map(attribute='port') | list }}"

  - name: print merged list
    debug:
      var: final_var

示例输出：

        },
        {
