Question

我正在尝试使用变量和前一个任务的结果作为输入。这是我的代码。

---
- hosts: localhost
  vars:
    v_hostname: XXXXXXXXXXXXX
    v_datacentre: DC-UK-LON-GS
    v_username: YYYYYYYY
    v_password: XXXXXXXX
  connection: local
  gather_facts: false

  tasks:
  - name: Find the folder for the VM
    vmware_guest_find:
      hostname: "{{ v_hostname }}"
      datacenter: "{{ v_datacentre }}"
      username: "{{ v_username }}"
      password: "{{ v_password }}"
      validate_certs: no
      name: MYVMNAME
    register: folder

   - debug:
       msg:
         - "{{ folder.folders }}"

   - name: Gather facts from VM
     connection: local
     gather_facts: false
     vmware_guest_facts:
       hostname: "{{ v_hostname }}"
       datacenter: "{{ v_datacentre }}"
       username: "{{ v_username }}"
       password: "{{ v_password }}"
       validate_certs: no
       folder: "{{ v_datacentre }}{{ folder.folders }}"
       name: MYVMNAME

最后一行尝试使用已定义的变量v_datacentre，并附加上一个任务中已注册事实的值。但是，连接会产生一些不需要的包裹字符：

通过调试正确打印folder.folders的结果，但在最后一步中，连接给出了：

"folder": "DC-UK-LON-GS[u'/vm/LON-GS-AD/LON-GS-AD-UNIX']",

我承认自己是一个可靠的新手，但我不明白[u＆＃39;来自。我只想使用组合字符串作为输入。任何人都可以解释或显示解决方案或指出一些初学者文档，以便进行这种变量使用吗？

感谢。

Answer 1

所以经过一些进一步的播放后，vmware_guest_find返回一个列表（并且它在文档中!!!）所以我需要选择第一个项目，如果只有一个组或循环它们。

folder: "{{ v_datacentre }}{{ folder.folders[0] }}"

这样做了。

将变量与Ansible中的事实连接起来
