ansible - 用于检查操作系统和给定挂载点的 Ansible 剧本

问题描述

下面是我检查以验证操作系统和挂载点的剧本。低于错误，无法调试。问题似乎出在后面的“验证挂载点”部分

 - hosts: all
   gather_facts: true
   vars:
    M1: ['RedHat','7']
    M2: ['/u01','/u02']
   tasks:

      when: >
       not ((ansible_os_family == M1[0] and ansible_distribution_major_version == M1[1]))
      fail:

    - name: "Verify Mount Points"

      fail:
       msg: "Mount Point doesn't exist"

输出：ansible-playbook -i dbservers test.yml

解决方案

gather_facts: true首先，使用ansible定义变量时需要设置。

其次，试着把注意力集中在这里的主要问题上。这些方面的东西应该起作用：

---
 - hosts: all
   gather_facts: true
   vars:
     M1: ['RedHat','7']
     M2: ['/u01','/u02']
   tasks:
    - name: "Verifying os and mount points"
      debug:
         msg: "{{ item }}"
      loop:
        - ansible_os_family 
        - ansible_distribution_major_version
        - ansible_mounts
      when: 
        - not item.ansible_os_family == 'M1[0]'  # you could also replace 'M1[0]' with 'Redhat'.
        - item.ansible_distribution_major_version == 'M1[1]'. # you could also replace 'M1[1]' with '7'.

     - fail:
         msg: "mount points not correctly"
       loop: ansible_mounts
       when: 
         - item.mount is defined
         - item.mount != 'M2[0]'
         - item.mount == 'M2[1]'

您不应该fails在单个任务中指定多个，因为失败是它自己的任务。
