Tags não aplicadas na função incluída no Ansible

  • 772

Eu criei um playbook simples do Ansible:

---
- hosts: all

  tasks:
    - name: Install Icinga2 on Windows
      include_role:
        name: my.icinga2.role
        apply:
          tags:
            - install-icinga2

A função contém este arquivo de tarefas:

---
- include_tasks: vars.yml
  tags: ['always']

- include_tasks: install.yml
  tags: ['install-icinga2-stack', 'install-icinga2']

- include_tasks: ido-install.yml
  when: icinga2_ido_enable == true
  tags: ['install-icinga2-stack', 'install-icinga2-ido']  

- include_tasks: configure.yml
  tags: ['install-icinga2-stack']

[...]

Este é o resultado quando executo o playbook:

me@ansible:~/ansible$ ansible-playbook plays/icinga2-client-win.yml -i staging.ini --limit windows

Por que o arquivo de tarefa de função configure.yml está incluído, pois deve ser incluído somente se eu aplicar a tag install-icinga2-stack e estiver aplicando a tag install-icinga2 ?

Além disso, percebo que o arquivo de tarefa de função ido-install.yml não está incluído apenas porque a variável icinga2_ido_enabletrue não está neste playbook (e seu padrão é false), não porque uma de suas tags não é aplicada (que deve ser o que eu quero) .

Onde estou errado?

    A aplicação de tags em include_role significa que as tags

    será aplicado às tarefas dentro do include.

    Em outras palavras, as tarefas na função incluída herdarão as tags aplicadas. É um mal-entendido esperar que as tags aplicadas selecionem as tarefas. Para selecionar as tarefas, use --tagse --skip-tagsna linha de comando ou nas definições de configuração do Ansible, use as opções TAGS_RUNe TAGS_SKIP.

    Um fato importante não é mencionado explicitamente na documentação de include_role . O parâmetro apply tags funciona apenas se toda a tarefa for tags: always. Isso é mostrado apenas nos exemplos .

        - name: Apply tags to tasks within included file
      include_role:
        name: install
        apply:
          tags:
            - install
      tags:
        - always

    Exemplo

    Vamos ter role1 com as 2 tarefas

        shell> cat roles/role1/tasks/main.yml 
    - debug:
        msg: 'This is task 2'
      tags: task2
    
    - debug:
        msg: 'This is task 3'
      tags: task3

    e uma cartilha

        shell> cat play1.yml 
    - hosts: localhost
      tasks:
        - debug:
            msg: 'This is task 1'
          tags: task1

        - include_role:
            name: role1
            apply:
              tags: role1
          tags: always

    Se executarmos o playbook sem nenhuma opção, todas as tarefas serão incluídas

        shell> ansible-playbook play1.yml | grep msg
        "msg": "This is task 1"
        "msg": "This is task 2"
        "msg": "This is task 3"

    Veja outras variações abaixo

        shell> ansible-playbook play1.yml --tags task1 | grep msg
        "msg": "This is task 1"
    shell> ansible-playbook play1.yml --tags task2 | grep msg
        "msg": "This is task 2"
    shell> ansible-playbook play1.yml --tags role1 | grep msg
        "msg": "This is task 2"
        "msg": "This is task 3"
    shell> ansible-playbook play1.yml --skip-tags role1 | grep msg
        "msg": "This is task 1"
    shell> ansible-playbook play1.yml --tags role1 --skip-tags task2 | grep msg
        "msg": "This is task 3"

    Nota . A listagem de tags não funciona como esperado.

        shell> ansible-playbook play1.yml --list-tags
    playbook: play1.yml
      play #1 (localhost): localhost    TAGS: []
          TASK TAGS: [always, task1]

    (Para o registro: include_role com as tags de aplicação não funciona #52063 )
