packet_ip_attachment

Provides a resource to attach elastic IP subnets to devices.

To attach an IP subnet from a reserved block to a provisioned device, you must derive a subnet CIDR belonging to one of your reserved blocks in the same project and facility as the target device.

For example, you have reserved IPv4 address block 147.229.10.152/30, you can choose to assign either the whole block as one subnet to a device; or 2 subnets with CIDRs 147.229.10.152/31' and 147.229.10.154/31; or 4 subnets with mask prefix length 32. More about the elastic IP subnets is here.

Device and reserved block must be in the same facility.

Example Usage

# Reserve /30 block of max 2 public IPv4 addresses in Parsippany, NJ (ewr1) for myproject
resource "packet_reserved_ip_block" "myblock" {
    project_id = "${packet_project.myproject.id}"
    facility = "ewr1"
    quantity = 2
}

# Assign /32 subnet (single address) from reserved block to a device
resource "packet_ip_attachment" "first_address_assingment" {
    device_id = "${packet_device.mydevice.id}"
    # following interpolation will result to sth like "147.229.10.152/32"
    cidr_notation = "${cidrhost(packet_reserved_ip_block.myblock.cidr_notation,0)}/32"
}

Argument Reference

The following arguments are supported:

• device_id - (Required) ID of device to which to assign the subnet
• cidr_notation - (Required) CIDR notation of subnet from block reserved in the same project and facility as the device

Attributes Reference

The following attributes are exported:

• id - The unique ID of the assignment
• device_id - ID of device to which subnet is assigned
• cidr_notation - Assigned subnet in CIDR notation, e.g. "147.229.15.30/31"
• gateway - IP address of gateway for the subnet
• network - Subnet network address
• netmask - Subnet mask in decimal notation, e.g. "255.255.255.0"
• cidr - length of CIDR prefix of the subnet as integer
• address_family - Address family as integer (4 or 6)
• public - boolean flag whether subnet is reachable from the Internet
