我对使用Ansible Core / Tower还是比较陌生，而我完全不知所措，这是导致以下问题的原因。在过去的两天里，我已经阅读了有关该主题的所有内容，但仍然陷入困境，寻求帮助。
这是我当前设置的内容（以及其他用于创建全新VPC的Ansible剧本，角色和任务）。
以下是我用来创建一组新子网（每个可用区一个）并从创建的结果中获取结果的任务。通过AWS控制台验证，这些任务都能完美地工作。
### Create the Internet-facing DMZ subnets ###
- name: Create Subnet(s) in VPC - DMZ
ec2_vpc_subnet:
state: present
vpc_id: "{{ new_vpc_info['vpcs'][0]['id'] }}"
region: "{{ vpc_region }}"
az: "{{ item.az }}"
cidr: "{{ item.subnet }}"
resource_tags:
Name: "{{ item.name }}"
Role: "{{ role_tag }}"
Team: "{{ team_tag }}"
Product Area: "{{ product_area_tag }}"
Portfolio: "{{ portfolio_tag }}"
with_items: "{{ dmz_subnet_az }}"
- name: Get Sunbet Info - DMZ
ec2_vpc_subnet_facts:
region: "{{ vpc_region }}"
filters:
"tag:Name": "{{ item.name }}"
with_items: "{{ dmz_subnet_az }}"
register: new_dmz_subnets
- debug:
var=new_dmz_subnets
下面提供了“ debug”命令的输出，将其截断以删除其余子网，并进行了删节，因此我不会大喊大叫，这与AWS控制台中的内容相匹配。

现在我要解决的问题正在解决，下面是我最近的尝试，由于我尝试了所有发现以使其正常运行，因此可能完全在左侧。我试图从已注册的“ new_dmz_subnets”变量中获取“ subnet_id”的列表，然后将其与在vars文件中设置的“名称”连接起来，最后使用该信息在每个子网。
### Create the NAT Gateway in VPC ###
- name: Set DMZ Subnet facts
set_fact:
subnet_id_items:
subnet_id: '{{ item.subnets | map(attribute="subnet_id") | list }}'
with_items: "{{ new_dmz_subnets }}"
register: subnet_id_list
- name: Set Name and DMZ Subnet loop facts
set_fact:
name_subnet_items:
name: "{{ nat_gateway.name }}"
subnet_id: "{{ item.subnet_id }}"
loop: "{{ subnet_id_list }}"
register: name_subnet_list
- debug:
var=name_subnet_list
- name: Create NAT Gateway, allocate new EIP, in VPC
ec2_vpc_nat_gateway:
state: present
subnet_id: "{{ item.subnet_id }}"
region: "{{ vpc_region }}"
wait: yes
if_exist_do_not_create: true
tags:
Name: "{{ item.name }}"
Role: "{{ role_tag }}"
Team: "{{ team_tag }}"
Product Area: "{{ product_area_tag }}"
Portfolio: "{{ portfolio_tag }}"
with_items: "{{ name_subnet_list }}"
register: new_nat_gateway
- debug:
var=new_nat_gateway
运行此设置时，我收到以下致命错误消息，在我尝试的每个变体中，该消息几乎都是相同的。
12:55:15
fatal: [localhost]: FAILED! => {
"msg": "The task includes an option with an undefined variable. The error was: 'ansible.utils.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'subnets'\n\nThe error appears to have been in '/var/lib/awx/projects/_6__erik_andresen_git/ansible/splunk_poc_playbook/roles/create_networking_role/tasks/create_gateways_task.yml': line 21, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n### Starting working on this Task ###\n- name: Set DMZ Subnet facts\n ^ here\n"
}
请告知我是否可以提供其他详细信息，并先感谢您的帮助！

我遇到了一个实际可行的设置！这可能不是最好的方法，但我仍然愿意接受建议，但至少可以奏效。
这是“ ec2_vpc_subnet”模块的代码，用于收集子网ID，以便以后在剧本中使用。
### Create the Internet-facing DMZ subnets ###
- name: Create Subnet(s) in VPC - DMZ
ec2_vpc_subnet:
state: present
vpc_id: "{{ vpc_id }}"
region: "{{ vpc_region }}"
az: "{{ item.az }}"
cidr: "{{ item.subnet }}"
resource_tags:
Name: "{{ item.name }}"
Role: "{{ role_tag }}"
Team: "{{ team_tag }}"
Product Area: "{{ product_area_tag }}"
Portfolio: "{{ portfolio_tag }}"
Created By: "{{ created_by }}"
with_items: "{{ dmz_subnet_az }}"
register: new_dmz_subnets
- name: Set facts for Subnet - DMZ
set_fact:
subnet_dmz_id: "{{ subnet_dmz_id | default({}) | combine({ item.subnet.tags.Name: item.subnet.id }) }}"
loop: "{{ new_dmz_subnets.results }}"
- debug:
var=subnet_dmz_id
这是使用“ ec2_vpc_nat_gateway”模块中的子网ID在每个可用区中创建NAT网关。
