aws_vpc
aws_vpc
provides details about a specific VPC.
This resource can prove useful when a module accepts a vpc id as an input variable and needs to, for example, determine the CIDR block of that VPC.
Example Usage
The following example shows how one might accept a VPC id as a variable and use this data source to obtain the data necessary to create a subnet within it.
variable "vpc_id" {}
data "aws_vpc" "selected" {
id = "${var.vpc_id}"
}
resource "aws_subnet" "example" {
vpc_id = "${data.aws_vpc.selected.id}"
availability_zone = "us-west-2a"
cidr_block = "${cidrsubnet(data.aws_vpc.selected.cidr_block, 4, 1)}"
}
Argument Reference
The arguments of this data source act as filters for querying the available VPCs in the current region. The given filters must match exactly one VPC whose data will be exported as attributes.
-
cidr_block
- (Optional) The cidr block of the desired VPC. -
dhcp_options_id
- (Optional) The DHCP options id of the desired VPC. -
default
- (Optional) Boolean constraint on whether the desired VPC is the default VPC for the region. -
filter
- (Optional) Custom filter block as described below. -
id
- (Optional) The id of the specific VPC to retrieve. -
state
- (Optional) The current state of the desired VPC. Can be either"pending"
or"available"
. -
tags
- (Optional) A mapping of tags, each pair of which must exactly match a pair on the desired VPC.
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. -
values
- (Required) Set of values that are accepted for the given field. A VPC 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 VPC.
The following attribute is additionally exported:
instance_tenancy
- The allowed tenancy of instances launched into the selected VPC. May be any of"default"
,"dedicated"
, or"host"
.
