无法使用从暂停注册的变量分配的变量 [英] Could not use variable assigned from variable registred from pause

问题描述

我在Ansible中使用条件，并且已经使用pause模块提示输入变量，但是我无法在剩余任务中使用该变量.我想根据最终用户插入的值来更改DNS服务器IP，但这没有用.

I'm using conditions in Ansible, and I have used the pause module to prompt for a variable, but I m not being able to use that variable for my remaining task. I wanted to change the DNS Server IP according to the value inserted from the end-user, but it didn't work.

代码:

 - name: os system
   pause:
    prompt: |
     Which os do you want to use?
      1- Windows Server
      2- CentOS_7
      3- CentOs_8
      4- Ubuntu
      5- Others
   register: os_system
 - name: Rename_PC
   pause:
    prompt: Enter New PC Name
   register: rename
   when: os_system.user_input == "1"
 - name: Domain Decision
   pause:
    prompt: Do you want your PC in Domain
   register: decision
   when: os_system.user_input == "1"
 - name: Domain Name
   pause:
     prompt: Enter Domain Name
   register: dc_name
   when: os_system.user_input == "1" and decision.user_input == "yes"
 - name: DNS IP
   pause:
     prompt: Enter DNS IP
   register: d_ip
   when: os_system.user_input == "1"  and decision.user_input "yes"
 - name: Domain DNS
   vmware_vm_shell:
    hostname: "{{ vc_name }}"
    username: "{{ myuser }}"
    password: "{{ mypass }}"
    validate_certs: no
    vm_username: Administrator
    vm_password: '{{ guest_password}}'
    vm_id: "{{ guest_name  }}"
    vm_shell: 'c:\windows\system32\windowspowershell\v1.0\powershell.exe'
    vm_shell_args:  '-command "(Set-DnsClientServerAddress -InterfaceAlias Ethernet0 -ServerAddress {{ d_ip }})"'
    wait_for_process: yes
   when: os_system.user_input == "1" and decision.user_input | bool
   delegate_to: localhost

如您所见，我在输入DNS IP 中以d_ip的形式输入了DNS ip，但是在下面尝试使用{{ d_ip }}时，它没有更改DNS IP，显示提示时，我已经迷惑了上面.

As you can see I have entered the DNS ip as d_ip in Enter DNS IP, but down below when I tried to use {{ d_ip }} it didn't change the DNS IP, that I have enetered above when the prompt was being displayed.

推荐答案

您丢失了pause

You are missing the fact that the return from pause is a dictionary and that the user input is stored in the user_input field.

因此，您的解决方法是仅使用d_ip.user_input而不是简单地使用d_ip:

So your fix is just to use d_ip.user_input instead of simply d_ip:

vm_shell_args: '-command "(Set-DnsClientServerAddress -InterfaceAlias Ethernet0 -ServerAddress {{ d_ip.user_input }})"'

---

请记住，这与您在上面的when条件下确实使用过的行为相同，实际上您在其中使用了user_input字段:

---

Mind that it is just the same behaviour as you already used on the when condition above, where you are indeed using the user_input field:

when: os_system.user_input == "1"
