- A dictionary array of resource tags of the form: { tag1: value1, tag2: value2 }. Tags in this list are used in conjunction with CIDR block to uniquely identify a VPC in lieu of vpc_id. Therefore, if CIDR/Tag combination does not exits, a new VPC will be created. VPC tags not on this list will be ignored.
