  private_subnet_cidrs          = ["10.0.3.0/24", "10.0.4.0/24"]

  endpoints                     = ["com.amazonaws.us-west-2.s3", "com.amazonaws.us-west-2.dynamodb"]
  endpoints_private_dns_enabled = [true, false]
  endpoints_security_group_ids  = [["sg-12345678"], ["sg-87654321"]]
  endpoints_subnet_ids          = [["subnet-1234abcd"], ["subnet-abcd1234"]]
