+
+# Data Source: aws_local_gateway
+
+`aws_local_gateway` provides details about a specific Local Gateway.
+
+## Example Usage
+
+The following example shows how one might accept a local gateway id as a variable.
+
+```hcl
+variable "local_gateway_id" {}
+
+data "aws_local_gateway" "selected" {
+  id = "${var.local_gateway_id}"
+}
+```
+
+## Argument Reference
+
+The arguments of this data source act as filters for querying the available
+Local Gateways in the current region. The given filters must match exactly one
+Local Gateway whose data will be exported as attributes.
+
+* `filter` - (Optional) Custom filter block as described below.
+
+* `id` - (Optional) The id of the specific Local Gateway to retrieve.
+
+* `state` - (Optional) The current state of the desired Local Gateway.
+  Can be either `"pending"` or `"available"`.
+
+* `tags` - (Optional) A mapping of tags, each pair of which must exactly match
+  a pair on the desired Local Gateway.
+
+More complex filters can be expressed using one or more `filter` sub-blocks,
+which take the following arguments:
+
+* `name` - (Required) The name of the field to filter by, as defined by
+  [the underlying AWS API](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeLocalGateways.html).
+
+* `values` - (Required) Set of values that are accepted for the given field.
+  A Local Gateway will be selected if any one of the given values matches.
+
+## Attributes Reference
+
+All of the argument attributes except `filter` blocks are also exported as
+result attributes. This data source will complete the data by populating
+any fields that are not included in the configuration with the data for
+the selected Local Gateway.
+
+The following attribute is additionally exported:
+
+* `outpost_arn` - Amazon Resource Name (ARN) of Local Gateway
+* `owner_id` - The ID of the AWS account that owns the Local Gateway.
+* `state` - The State of the local gateway.
