Use campos de saída registrados como variáveis ​​no playbook do Ansible

  • 772

Por favor, informe como usar dados registrados de uma tarefa como variáveis ​​para outra tarefa no mesmo manual.

Manual de instruções:

---
- name: RouterOS test with API
  hosts: localhost
  vars:
    hostname: "some_host"
    username: "api"
    password: "some_password"
    gather_subset: all
  module_defaults:
    group/community.routeros.api:
      hostname: "{{ hostname }}"
      password: "{{ password }}"
      username: "{{ username }}"
      tls: true
      force_no_cert: false
      validate_certs: false
      validate_cert_hostname: false
  tasks:

  - name: Add wg tuns
    ignore_errors: true
    community.routeros.api:
      path: "interface wireguard"
      add: "name={{ item.name }} listen-port={{ item.port }} comment={{ item.comment }}"
    loop:
      - { name: 'wg1', port: '111', comment: 'com1' }
      - { name: 'wg2', port: '222', comment: 'com2' }
      - { name: 'wg3', port: '333', comment: 'com3' }

  - name: Get wg link-local addrs
    community.routeros.api:
      path: ipv6 address
      extended_query:
        attributes:
          - address
          - interface
        where:
          - attribute: "interface"
            is: "=="
            value: "{{ item.name }}"
    loop:
      - { name: 'wg1' }
      - { name: 'wg2' }
      - { name: 'wg3' }
    register: extended_queryout

  - name: Dump "Extended query example" output
    ansible.builtin.debug:
      msg: '{{ extended_queryout }}'

O Playbook está criando 3 (via loop) interfaces wireguard e eu preciso usar esses endereços link-local de interfaces como variáveis ​​como wg1.address, wg2.address, wg3.address . Agora eu só consigo ver muita saída gerada com

  - name: Dump "Extended query example" output
    ansible.builtin.debug:
      msg: '{{ extended_queryout }}'

assim:

Como definir o valor da variável wg1.address fe80::caa4:e31c:dd63:7598/64, o valor da variável wg2.address fe80::c0eb:fadb:2da0:50f5/64 e o valor wg3.address fe80::28d1:7b9b:92:ed43/64.

Agradeço antecipadamente.

Esperando ver a variável wg1.address valor fe80::caa4:e31c:dd63:7598/64, a variável wg2.address valor fe80::c0eb:fadb:2da0:50f5/64 e wg3.address valor fe80::28d1:7b9b:92:ed43/64.

  1. mapear o atributo msg

      ifc_addr: "{{ extended_queryout.results |
                map(attribute='msg') |
                flatten }}"

    para obter a lista

      ifc_addr:
  - address: fe80::caa4:e31c:dd63:7598/64
    interface: wg1
  - address: fe80::c0eb:fadb:2da0:50f5/64
    interface: wg2
  - address: fe80::28d1:7b9b:92:ed43/64
    interface: wg3

    Você pode selecionar e mapear o que quiser ou pode converter a lista em um dicionário

      ifc_addr_dict: "{{ ifc_addr |
                     items2dict(key_name='interface',
                                value_name='address') }}"

    dá o dicionário trivial

      ifc_addr_dict:
    wg1: fe80::caa4:e31c:dd63:7598/64
    wg2: fe80::c0eb:fadb:2da0:50f5/64
    wg3: fe80::28d1:7b9b:92:ed43/64

    Exemplo de um manual completo para testes

    - hosts: localhost

  vars_files: extended_queryout.yml

  vars:

    ifc_addr: "{{ extended_queryout.results |
                  map(attribute='msg') |
                  flatten }}"

    ifc_addr_dict: "{{ ifc_addr |
                       items2dict(key_name='interface',
                                  value_name='address') }}"

  tasks:

    - debug:
        var: extended_queryout

    - debug:
        var: ifc_addr

    - debug:
        var: ifc_addr_dict

  2. Best Answer

    Você pode acessar o endereço MAC de cada interface assim:

    - name: Print mac address of iface wg1
  ansible.builtin.debug:
    msg: "{{ extended_queryout.results|json_query('[0].msg[0].address') }}"
                                        # see: -----^ 

- name: Print mac address of iface wg2
  ansible.builtin.debug:
    msg: "{{ extended_queryout.results|json_query('[1].msg[0].address') }}"
                                        # see: -----^

    Para armazenar o valor em um fato, use o set_factmódulo:

    - name: Store the mac addresses as facts
  ansible.builtin.set_fact:
    wg1:
      address: "{{ extended_queryout.results|json_query('[0].msg[0].address') }}"
    wg2:
      address: "{{ extended_queryout.results|json_query('[1].msg[0].address') }}"
    wg3:
      address: "{{ extended_queryout.results|json_query('[2].msg[0].address') }}"
