如何将部署的虚拟机（vmware_guest）的变量传递给角色以进行进一步配置

Question

Ansible 新手，在使用 vmware_guest 新部署的虚拟机上运行角色时遇到困难。 尝试收集在某些角色中使用的变量，但这些似乎没有被转移。

我有这个剧本，可以部署并添加主机以进行进一步配置。 VM 部署正确。

如果有一些如何做到这一点的线索，我们将不胜感激。

尝试了多种方法，但不确定我是否理解应该如何完成。

您遇到变量委托/范围的问题。

让我解释一下： 例如在这个变量中：

var_vm_ip: "{{ vm_info.instance.ipv4 }}"

您在另一台主机上有此变量，而不是在当前主机上。考虑到第一个任务在“localhost”上执行，其余任务在库存组“vmware_vms”上执行。

我们该如何解决这个问题？使用：[主机变量][1] 首先，我会在第一个任务结束之前创建一个 set_fact 步骤，这样我们就可以更轻松地将变量传递给第二个任务：

- name: SetFact vminfo
      set_fact:
        vm_information: "{{ vm_info }}"

- name: Run Additional Configurations
  hosts: vmware_vms
  gather_facts: no
  roles:
    - role: base
      vars:
        var_vm_name: "{{ vm_name }}"
        var_vm_ip: "{{ hostvars['localhost'].vm_information.instance.ipv4 }}"
        var_vm_domain: "{{ hostvars['localhost'].vm_information.customization.domain }}"
        var_vm_fqdn: "{{ hostvars['localhost'].vm_information.customization.hostname }}"
        var_vm_dnsservers: "{{ hostvars['localhost'].vm_information.customization.dns_servers }}"
