如何将变量转换为包含剧本？

Question

我有剧本，其中包括。还有var_prompt "name_VM“，我需要包含剧本"new-vm.yml”中的transfer变量，但是我有错误：

任务主机名****************************************************************致命: 192.168.250.102: FAILED！=> {“variable”：true，"msg"：“args”字段有一个无效的值，该值似乎包含一个未定义的变量。错误是：{{ name_VM }：'name_VM‘是未定义的\n\n该错误似乎出现在’/etc/ansible/playbook/Task/new-vm.yml‘：第7行，第7列，但可能\n在文件的其他地方，这取决于确切的语法问题。\n冒犯行似乎是：\n pre_tasks:\n -主机名：\n pre_tasks：\n\n“}

如何在pre_tasks中传递变量包括剧本？

主要剧本：

- hosts: localhost
  gather_facts: false
  connection: local
  become: true
  vars_files:
    - ../roles/vm-create/vars/am-default.yml
  vars_prompt:
    - name: "name_VM"
      prompt: "VM name:"
      private: no
      default: "vm001"

    - name: "size_hard"
      prompt: "Size hard disk (Gb)"
      private: no
      default: "16"

    - name: "size_memory"
      prompt: "Size memory (Mb)"
      private: no
      default: "2048"

    - name: "count_CPU"
      prompt: "Count CPU:"
      private: no
      default: "2"

  roles:
    - vm-create

  tasks:
    - include: tasks/check-ip.yml

- include: tasks/new-vm.yml

新的-vm手册：

- hosts: temp
  vars:
      ldap_server: ldap://ldap.example.com
      agent_server: zabbix.aexample.com
  pre_tasks:
    - hostname:
        name: "{{ name_vm }}"
  roles:
    - { role: zabbix-agent, tags: [ 'zabbix' ] }
    - { role: ldap-client, tags: [ 'ldap' ] }
    - { role: motd, tags: [ 'motd' ] }
  tasks:
    - telegram:
        token: 'bot12345:XXXXXX'
        chat_id: XXXXX
        msg: "New VM {{ ansible_hostname }} ({{ ansible_all_ipv4_addresses }}) is created and has been configured."
      tags:
        - telegram

check_ip.yml，在其中添加主机：

- vsphere_guest:
    vcenter_hostname: "{{ vcenter_hostname }}"
    username: "{{ vcenter_user }}"
    password: "{{ vcenter_pass }}"
    guest: "{{ name_VM }}"
    vmware_guest_facts: yes
    validate_certs: no
  register: vsphere_facts
  until: vsphere_facts.ansible_facts.hw_eth0.ipaddresses[0] | match("192.168.250.")
  retries: 6
  delay: 10
- name: Ensure virtual machine is in the dynamic inventory
  add_host:
    name: "{{ vsphere_facts.ansible_facts.hw_eth0.ipaddresses[0] }}"
    ansible_user: root
    ansible_ssh_pass: pass
    groups: temp

在您的例子中，name_VM是游戏绑定的，在第二次播放时是不可见的。

您需要将一个事实分配给temp主机(我猜您在vm-create角色中的某个地方使用了add_host；所以只需在那里添加name_vm: "{{ name_VM }}"主机事实)。

然后，在第二次播放中，您可以访问{{ name_vm }}主机事实。

更新:示例，基于问题编辑。

- name: Ensure virtual machine is in the dynamic inventory
  add_host:
    name: "{{ vsphere_facts.ansible_facts.hw_eth0.ipaddresses[0] }}"
    name_vm: "{{ name_VM }}"
    ansible_user: root
    ansible_ssh_pass: pass
    groups: temp
