如何遍历 ansible playbook 输出？ [复制]

Question

我想获得我在剧本中 ping 的所有 IP 地址的结果。例如，我正在尝试 ping 三个不同的 IP 地址，我不想手动计算必须设置多少 output.results[]。这是我编辑的剧本：

- name: Testing Napalam Ping Module
  hosts: arista
  gather_facts: no
  vars:
    output_results: []
  tasks:
    - name: Napalm ping
      napalm_ping:
        provider: "{{creds}}"
        destination: "{{item}}"
      with_items:
        - 1.1.1.1
        - 8.8.8.8
        - 4.2.2.2
      register: output
    - name: I am gonna set the output as a fact
      set_fact:
        ping_results: "{{output.results[1].item}}"
    - name: I am gonna print out the ping_results fact
      debug:
        var: ping_results
    - name: I am gonna set the output as a fact
      set_fact:
        packet_loss: "{{output.results[1].results.success}}"
    - name: I am gonna print out the packet_loss fact
      debug:
        var: packet_loss
    - debug:
        msg: "{{ping_results}} is pingable from {{ansible_host}} with {{item.key}} =  {{item.value}} out of 5 packets"
      with_dict: "{{packet_loss}}"
      when: "item.key == 'packet_loss'"

这是输出：

TASK [debug] *****************************************************************************************************************************
ok: [pynet-sw5] => (item={'value': 0, 'key': u'packet_loss'}) => {
    "msg": "1.1.1.1 is pingable from arista5.twb-tech.com with packet_loss =  0 out of 5 packets"
}
ok: [pynet-sw6] => (item={'value': 0, 'key': u'packet_loss'}) => {
    "msg": "1.1.1.1 is pingable from arista6.twb-tech.com with packet_loss =  0 out of 5 packets"
}
ok: [pynet-sw7] => (item={'value': 4, 'key': u'packet_loss'}) => {
    "msg": "1.1.1.1 is pingable from arista7.twb-tech.com with packet_loss =  4 out of 5 packets"
}
ok: [pynet-sw8] => (item={'value': 1, 'key': u'packet_loss'}) => {
    "msg": "1.1.1.1 is pingable from arista8.twb-tech.com with packet_loss =  1 out of 5 packets"

因为我手动设置了 output.results[1] 的事实，所以我只能看到 1.1.1.1 结果，但我想查看所有三个 IP 地址的结果？有办法吗？

您可以在 playbook 中使用include_tasks 模块，如下所示

- name: Testing Napalam Ping Module
  hosts: arista
  gather_facts: no
  tasks:
    - name: Napalm ping and debug
      include_tasks: napalm-tasks.yml
      with_items:
        - 1.1.1.1
        - 8.8.8.8
        - 4.2.2.2
      loop_control:
        loop_var: destination_host

并将所有其他相关任务放在 napalm-tasks.yml 中以循环它们以 ping 和调试输出：

- name: Napalm ping
  napalm_ping:
    provider: "{{ creds }}"
    destination: "{{ destination_host }}"
  register: output

- name: I am gonna set the output as a fact
  set_fact:
    ping_results: "{{ output }}"

- name: I am gonna print out the ping_results fact
  debug:
    var: ping_results

- name: I am gonna set the output as a fact
  set_fact:
    packet_loss: "{{ output.results.success }}"

- name: I am gonna print out the packet_loss fact
  debug:
    var: packet_loss

- debug:
    msg: "{{ ping_results }} is pingable from {{ ansible_host }} with {{ item.key }} =  {{ item.value }} out of 5 packets"
  with_dict: "{{ packet_loss }}"
  when: "item.key == 'packet_loss'"
