ansible任务控制-包含include

include的使用场景比较简单，就是多个playbook需要执行相同的操作，例如有5个playbook，这5个playbook都是安装不同的服务，但是都会安装nginx，同时也都会重启nginx，这个时候就可以使用include

首先编辑一个没有play的yml，其他的yml中使用include来包含这个yml

cat > task_include_tem.yml <<EOF
- name: restart nginx
  service:
    name: nginx
    state: restarted
EOF

编辑a.yml

这里我们仅仅使用shell模块echo一句话，然后重启nginx

cat > a.yml << EOF
- hosts: all
  tasks:
    - name: print test a
      shell: echo 'test a'
    - name: restat nginx
      include: ./task_include_tem.yml
EOF

执行a.yml

$ ansible-playbook a.yml 

PLAY [all] *********************************************************************************************************************************************

TASK [Gathering Facts] *********************************************************************************************************************************
ok: [devops03]
ok: [devops02]
ok: [devops01]

TASK [print test a] ************************************************************************************************************************************

changed: [devops02]
changed: [devops03]
changed: [devops01]

PLAY RECAP *********************************************************************************************************************************************
devops01                   : ok=3    changed=2    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0   
devops02                   : ok=3    changed=2    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0   
devops03                   : ok=3    changed=2    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0   

编辑b.yml

cat > b.yml << EOF
- hosts: all
  tasks:
    - name: print test b
      shell: echo 'test b'
    - name: restat nginx
      include: ./task_include_tem.yml
EOF

执行b.yml

$ ansible-playbook b.yml 

PLAY [all] *********************************************************************************************************************************************

TASK [Gathering Facts] *********************************************************************************************************************************
ok: [devops02]
ok: [devops03]
ok: [devops01]

TASK [print test b] ************************************************************************************************************************************
changed: [devops03]
changed: [devops02]
changed: [devops01]

TASK [restart nginx] ***********************************************************************************************************************************
changed: [devops03]
changed: [devops02]
changed: [devops01]

PLAY RECAP *********************************************************************************************************************************************
devops01                   : ok=3    changed=2    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0   
devops02                   : ok=3    changed=2    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0   
devops03                   : ok=3    changed=2    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0   

yml文件中的 include 还可以写成 include_tasks

cat > b.yml << EOF
- hosts: all
  tasks:
    - name: print test b
      shell: echo 'test b'
    - name: restat nginx
      include_tasks: ./task_include_tem.yml
EOF

执行的时候会多了一个 included: /root/yml/task_include_tem.yml for devops01, devops02, devops03 提示

$ ansible-playbook b.yml
