Ansible thông báo lỗi toàn cầu khi một tác vụ không thành công trên tất cả các máy chủ

For example, given the inventory for testing

shell> cat hosts
host1 ansible_net_hostname=host_123_A
host2 ansible_net_hostname=host_123_B
host3 ansible_net_hostname=host_123_C

The play below shows how to find the lists

- hosts: all
  gather_facts: false
  tasks:
    - debug:
        var: ansible_net_hostname
    - debug:
        msg: |
          All names: {{ _names }}
          Search names: {{ _search }}
      vars:
        _names: "{{ hostvars|json_query('*.ansible_net_hostname') }}"
        _search: "{{ _names|select('search', '123')|list }}"
      run_once: true

gives

TASK [debug] ***********************************************************
ok: [host1] => 
  ansible_net_hostname: host_123_A
ok: [host2] => 
  ansible_net_hostname: host_123_B
ok: [host3] => 
  ansible_net_hostname: host_123_C

TASK [debug] ***********************************************************
ok: [host1] => 
  msg: |-
    All names: ['host_123_A', 'host_123_B', 'host_123_C']
    Search names: ['host_123_A', 'host_123_B', 'host_123_C']

Compare the length of the lists

    - debug:
        msg: all of the hostnames contains 123
      vars:
        _names: "{{ hostvars|json_query('*.ansible_net_hostname') }}"
        _search: "{{ _names|select('search', '123')|list }}"
      when: _names|length == _search|length
      run_once: true

^{(Credit @Zeitounator for pointing to this option.)}

The query above works if you target all hosts in the inventory. If you'd like to target a group of hosts use the special variable ansible_play_hosts_all and extract the variables from the hostvars. For example, given the inventory

shell> cat hosts
[test_123]
host[0001:1024]

[test_123:vars]
ansible_net_hostname=host_123_A

The play

- hosts: test_123
  gather_facts: false
  tasks:
    - debug:
        msg: |
          All names: {{ _names|length }}
          Search names: {{ _search|length }}
      vars:
        _names: "{{ ansible_play_hosts_all|
                    map('extract', hostvars, 'ansible_net_hostname')|
                    list }}"
        _search: "{{ _names|select('search', '123')|list }}"
      run_once: true

gives

TASK [debug] *****************************************************
ok: [host0001] => 
  msg: |-
    All names: 1024
    Search names: 1024

To evaluate the condition compare the length of the lists as before.
