如何将标签应用于Ansible任务文件中的每个命令？

Ansible最佳做法文档包含以下示例代码：

---
# file: roles/common/tasks/main.yml

- name: be sure ntp is installed
  yum: name=ntp state=installed
  tags: ntp

- name: be sure ntp is configured
  template: src=ntp.conf.j2 dest=/etc/ntp.conf
  notify:
    - restart ntpd
  tags: ntp

- name: be sure ntpd is running and enabled
  service: name=ntpd state=running enabled=yes
  tags: ntp

我希望避免重复tags: ntp行。这些指令中的每一个都可以继承标签吗？

您可以使用-块：

➜  ~ cat become.yml
---
- hosts: localhost
  user: vagrant
  tasks:
   - block:
      - shell: whoami
        register: result

      - debug: var=result.stdout

      - name: become_root_user
        become: true
        become_user: root
        shell: whoami
        register: sudo_test_result

      - debug: var=sudo_test_result.stdout
     tags:
      - block1
   - block:
      - name: creating_new_app_user
        become: true
        become_user: root
        become_method: sudo
        user: name=app_user password=Bzs310di86b6E groups="adm,sudo" system=yes state=present

      - name: become_app_user
        become: true
        become_user: app_user
        become_method: sudo
        shell: whoami
        register: app_user_test_result

      - debug: var=app_user_test_result.stdout
     tags:
      - block2

〜ansible-playbook -i realtime-automation / hosts-slaves成为.yml --tags“ block1”

在您的特定情况下：

---
- block:
    - name: be sure ntp is installed
      yum: name=ntp state=installed

    - name: be sure ntp is configured
      template: src=ntp.conf.j2 dest=/etc/ntp.conf
      notify:
        - restart ntpd

    - name: be sure ntpd is running and enabled
      service: name=ntpd state=running enabled=yes
  tags: ntp
