$ cat pb_vpc_validate.yml- name: Validate VPC Build  hosts: all  gather_facts: no  environment:    AWS_ACCESS_KEY: "{{ aws_access_key }}"    AWS_SECRET_KEY: "{{ aws_secret_key_id }}"    AWS_REGION: "{{ aws_region }}"  tasks:    - name: Get VPC facts      ec2_vpc_net_facts:        filters:          "tag:Name": "{{ vpc_name }}"      register: vpc_facts    - name: Validate VPC Info      assert:        that:          - vpc_facts.vpcs[0].cidr_block == vpc_cidr          - vpc_facts.vpcs[0].tags.Name == vpc_name      when: vpc_facts.vpcs != []
