aws_default_subnet
Provides a resource to manage a default AWS VPC subnet in the current region.
The aws_default_subnet behaves differently from normal resources, in that
Terraform does not create this resource, but instead "adopts" it
into management.
Example Usage
Basic usage with tags:
resource "aws_default_subnet" "default_az1" {
availability_zone = "us-west-2a"
tags {
Name = "Default subnet for us-west-2a"
}
}
Argument Reference
The arguments of an aws_default_subnet differ from aws_subnet resources.
Namely, the availability_zone argument is required and the vpc_id, cidr_block, ipv6_cidr_block,
map_public_ip_on_launch and assign_ipv6_address_on_creation arguments are computed.
The following arguments are still supported:
tags- (Optional) A mapping of tags to assign to the resource.
Removing aws_default_subnet from your configuration
The aws_default_subnet resource allows you to manage a region's default VPC subnet,
but Terraform cannot destroy it. Removing this resource from your configuration
will remove it from your statefile and management, but will not destroy the subnet.
You can resume managing the subnet via the AWS Console.
Attributes Reference
The following attributes are exported:
id- The ID of the subnetavailability_zone- The AZ for the subnet.cidr_block- The CIDR block for the subnet.vpc_id- The VPC ID.ipv6_association_id- The association ID for the IPv6 CIDR block.ipv6_cidr_block- The IPv6 CIDR block.
