目标：使代码自动化，使其与ovf无关。构建一个剧本，以允许在不更改YAML剧本的情况下部署具有任何自定义ovf属性和网络接口名称的任何OVF模板。
环境： Ansible 2.8.7 python版本= 3.6.8
代码示例：
**Dicts: cust-ovf-answer.yml**
custovfnetworkanswers:
Management: "vmportgroup"
custovfanswers:
fqdn: "s0u1tst.dmn.local"
dns1: "10.100.0.14"
dns2: "10.100.0.17"
ntp1: "ntp1.dmn.local"
ntp2: "ntp2.dmn.local"
ipv4.how: "Manual"
ipv4.addr: "10.100.0.135"
ipv4.mask: "255.255.255.224"
ipv4.gw: "10.100.0.158"
**Playbook: Deploy_OVF_to_System.yml**

如果我全部硬编码，则所有内容都会按预期导入。

我认为您的问题是 args:。您可以直接注入 dict 变量。顺便说一句，您不需要使用 to_json 转换过滤器，因为 Ansible 会处理它。
[…]
disk_provisioning: "thick"
networks: "{{ custovfnetworkanswers }}"
power_on: no
[…]
inject_ovf_env: yes
properties: "{{ custovfanswers }}"
delegate_to: localhost
[…]
在某些情况下，您必须提供的键需要是动态的（不可预测的键名或列表长度）。要解决这个问题，您可以使用 jinja2 将变量伪造为 json 字符串。
dict 样本动态列表：
vars:
custom_networks: >
[ {% for nic in nics %}
{ 'name':'{{ nic.id }}',
'mac':'{{ nic.mac }}',
'ip': '{{ nic.ip }}'
}{% if not loop.last %},{% endif %}
{% endfor %}
]
动态键名：
vars:
custom_ovf_input: "{ '{{ network_name }}': '{{ network_address }}' }"
然后你可以直接使用那个伪造的变量（不需要使用任何过滤器将其转换为 yaml Ansible 会处理它）。
