Question

我想获取我在剧本中ping的所有IP地址的结果。例如，我尝试对三个不同的IP地址执行ping操作，而我不想手动计算必须设置的output.results []个数。这是我编辑过的剧本：

def generate_array():
   while True:
    X = np.empty((1, 9008))
    y = np.empty((1), dtype=int)
    # Some processing
    X[0] = row
    y[0] = label
    yield(X,y)

这是输出：

- 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'"

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

您可以按以下方式在剧本中使用include_tasks模块

- 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中以遍历它们以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'"

如何遍历ansible剧本输出？
