Find VPC ID of a VPC on AWS

Module ec2_vpc_net_info returns a list of VPCs that looks like this:

  "vpcs": [
      {
          "cidr_block": "172.31.0.0/16",
          ...
          "state": "available",
          "tags": {
              "Name": "Default"
          },
          "vpc_id": "vpc-c4c7abcd"
      },
      {
          "cidr_block": "10.1.0.0/24",
          ...
          "state": "available",
          "tags": {
              "Name": "echong-vpc"
          },
          "vpc_id": "vpc-070c059d2b78d1234"
      }
  ]

For exmple, to get the vpc_id of variable name vpc_name, we can use json_query:

  - name: Find VPC ID matching vpc_name
    debug:
      msg: ""
    vars:
      _query: "[?tags.Name == ''].vpc_id"

Of course, it will be easier to just use filter in ec2_vpc_net_info module:

  - name: Gather VPC info with filter
    amazon.aws.ec2_vpc_net_info:
      aws_secret_key: ""
      aws_access_key: ""
      region: ""
      filters:
        "tag:Name": ""
    register: _vpc_info
