YAML_11 when条件判断

当系统负载超过0.7时，则关掉httpd

ansible]# vim when.yml

---

- hosts: cache

  remote_user: root

  tasks:

    - shell: uptime | awk '{printf("%.2f",$(NF-2))}'

      register: result

    - service:

        name: httpd

        state: stopped

        when: result.stdout|float < 0.7

       (此处写<，方便查看效果）

 

ansible]# ansible-playbook when.yml
