subnet resource

Description

SubnetResource is an EC2 subnet: an IP range carved out of a VPC in one Availability Zone. The VPC, the zone, the IPv4 and IPv6 ranges, and an Outpost ARN are fixed when the subnet is created, so a change to any of them replaces the subnet; the launch-time options are reconciled in place. CreateSubnet accepts only the address and placement fields. The launch-time options each have no create-time setting and are applied after the subnet exists, one ModifySubnetAttribute call per option. A nil option is never sent: the value is AWS's to decide, the default for a new subnet or whatever an earlier apply set. EC2 has no reset call, so restoring a default after an apply set the option means setting the default explicitly.

Private dns hostname type on launch rules

private-dns-hostname-type-on-launch must be ip-name or resource-name.

Rule logic

When

input.private-dns-hostname-type-on-launch != null

Require

input.private-dns-hostname-type-on-launch == 'ip-name'
|| input.private-dns-hostname-type-on-launch == 'resource-name'

Enable lni at device index rules

enable-lni-at-device-index must be a positive device position.

Rule logic

When

input.enable-lni-at-device-index != null

Require

input.enable-lni-at-device-index > 0
