Question

我有一组任务，这些任务由单独的角色组成，这些角色以“何时”条件运行，仅在某些主机上执行，在这些任务中，我使用产生我所寻找内容的vars / set_facts拉取特定值-但整个过程的最后一个角色是从所有人那里获取结果/事实，并将其应用于Jinja HTML模板。

最初，我在一个角色中混合了多个任务，这些任务将与包含子组的单个组一起运行-这些是由“何时”条件决定的-因为我已经将它们分开，所以请确保没有重复的变量/事实，甚至引入了一个桥接角色，该角色将set_facts用作vars，然后再次将其设置为vars，但使用了proxy_to：localhost。

  hosts: "{{ site_code }}"
  ignore_errors: True
  gather_facts: yes

  tasks:

    - name: DMVPN Primary Check
      include_role:
        name: dmvpn-primary
      when: inventory_hostname in groups['dmvpn_primary']

    - name: DMVPN Backup Check
      include_role:
        name: dmvpn-secondary
      when: inventory_hostname in groups['dmvpn_secondary']

    - name: Fact Cache
      include_role:
        name: fact-gather

    - name: HTML Report
      include_role:
        name: html-report
      run_once: true

当我将主机限制在一个组中时，proxy_to会选择该主机，然后选择它自己的事实，但是将多台主机与{{site_code}} var组合在一起会导致冲突，最终导致错误“ AnsibleUndefinedVariable” < / p>

编辑：这是dmvpn角色，事实收集角色和html.j2文件的片段，显示了几个变量的流，这些变量最终以致命的形式出现：[site-vpn01-> 127.0.0.1]：失败！ => { “已更改”：错误， “ msg”：“ AnsibleUndefinedVariable：'dmvpn1_host_name'未定义”

roles \ dmvpn-primary

  - name: Primary Tunnel Up/Down
    vars:
      dmvpn1_tun_stat_0: "{{ dmvpn1_result.stdout[0] }}"
      dmvpn1_tun_stat_1: "{{ dmvpn1_tun_stat_0.split() }}"
      dmvpn1_tun_stat_2: "{{ dmvpn1_tun_stat_1[3] }}"
    set_fact:
      dmvpn1_tun_status: "{{ dmvpn1_tun_stat_2 }}"
      dmvpn1_hostname: "{{ inventory_hostname }}"
      dmvpn1_host_ip: "{{ ansible_host }}"
      cacheable: yes

角色\事实收集：

  - name: Primary Inventory Facts
    vars:
      dmvpn1_host_name: "{{ dmvpn1_hostname }}"
      dmvpn1_host_ipv4: "{{ dmvpn1_host_ip }}"
      dmvpn1_google_dns1_icmp: "{{ dmvpn1_icmp1_loss }}"
    set_fact:
      dmvpn1_host_name: "{{ dmvpn1_host_name }}"
      dmvpn1_host_ipv4: "{{ dmvpn1_host_ipv4 }}"
      dmvpn1_google_dns1_ip: "{{ dmvpn1_google_dns1_ip }}"
      dmvpn1_google_dns1_icmp: "{{ dmvpn1_google_dns1_icmp }}"
      dmvpn1_google_dns1_status: "{{ 'SUCCESS' if ('100' in dmvpn1_google_dns1_icmp) else 'FAIL' }}"
      cacheable: yes
    delegate_to: 127.0.0.1
    delegate_facts: True
    when: inventory_hostname in groups['dmvpn_primary']

templates \ html.j2：

    <tr>
        {% if inventory_hostname in groups['dmvpn_primary'] %}
            <td>{{ location }}</td>
            <td>{{ sitecode[2]|upper }}</td>
            <td>{{ dmvpn1_host_name }}</td>
            <td>{{ dmvpn1_host_ipv4 }}</td>
            <td>ICMP</td>
            <td>Google DNS1</td>
            <td>{{ dmvpn1_google_dns1_icmp }}%</td>
            <td>{{ dmvpn1_google_dns1_status }}</td>
            <td>
            {% if 'SUCCESS' in dmvpn1_google_dns1_status %}
             - 
            {% else %}
            {{ slack_url }}
            {% endif %}
            </td>
        {% else %}
        {% endif %}
    </tr>

缓存后如何在有条件的情况下使用委托角色中的set_facts？
