给tasks打tags

可以给tasks中的每个任务打tags以列表的方式书写，可以打多个：['tag1','tag2','tag3']

也可以给整个tasks打大标签，作为多个任务的共有tags

示例如下

---

• hosts: PC

  remote_user: jack

  tasks:

  • name: copy hosts

    tags: ['hosts']

    copy:

    src: /etc/hosts

    dest: /home/jack/

    backup: yes

• hosts: PD

  remote_user: root

  tasks:

  • name: add user

    tags: ['user']

    user:

    name: jiao

    uid: 1500

    password: $6$iWcHDljL6NvS45z9$Y/WMWbLhvjSOgl.NOM2sEpBbN6A4ghQiUFwImiyzmVq2JhVp.b3taieZFR4fx3npQY3Dk6OkkUuwnfGqw/DvA.

  • name: add cron

    tags: ['cron']

    cron:

    name: cron for jiao

    user: jiao

    minute: '0'

    hour: '15'

    job: echo my love

    notify: hd1

  • meta: flush_handlers
  • name: touch file

    tags: ['file']

    file:

    path: /home/jiao/test

    state: touch

    owner: jiao

    group: jiao

    mode: 0777

• hosts: PB

  remote_user: root

  tasks:

  • name: install apache

    tags: ['apache']

    yum:

    name: httpd

    state: installed

    notify: hd2

  handlers:

  • name: reload crond

    listen: hd1

    service:

    name: crond

    state: reloaded

  • name: restart httpd

    listen: hd2

    service:

    name: httpd

    state: restarted

查看tags： ansible-playbook --list-tags test9.yml

执行某个tags：ansible-playbook --tags apache test9.yml

执行多个tags：ansible-playbook --tags user,file test9.yml

跳过已执行的tags：ansible-playbook --skip-tags cron,file,user,apache test9.yml

执行未打tags的任务：ansible-playbook --tags untagged test9.yml

执行所有打tags的任务：ansible-playbook --tags tagged test9.yml

ansible还预置了5个特殊tag，这5个特殊tag分别为

always任务就总是会被执行，除非你使用'--skip-tags'选项明确指定不执行对应的任务

never(2.5版本中新加入的特殊tag)

tagged 打过标签的任务

untagged 未打过标签的任务

all 所有任务
