IP Failover

Creates and manages ipfailover objects.

Manages IP Failover groups on IonosCloud.

  name                = "Datacenter Example"
  location            = "us/las"

  size                  = 1
  name                  = "IP Block Example"
}

resource "ionoscloud_lan" "example" {
  datacenter_id         = ionoscloud_datacenter.example.id
  public                = true
  name                  = "Lan Example"
}

  availability_zone     = "ZONE_1"
  cpu_family            = "AMD_OPTERON"
  image_name            = "Ubuntu-20.04"
  image_password        = random_password.server_image_password.result
  volume {
    name                = "system"
    size                = 14
    disk_type           = "SSD"
  }
  nic {
    lan                 = "1"
    dhcp                = true
    firewall_active     = true
    ips                 = [ ionoscloud_ipblock.example.ips[0] ]
  }
}

resource "ionoscloud_ipfailover" "example" {
  depends_on            = [ ionoscloud_lan.example ]
  datacenter_id         = ionoscloud_datacenter.example.id
  lan_id                = ionoscloud_lan.example.id
  ip                    = ionoscloud_ipblock.example.ips[0]
  nicuuid               = ionoscloud_server.example.primary_nic
}
resource "random_password" "server_image_password" {
  length           = 16
  special          = false
}

Argument reference

• datacenter_id - (Required)[string] The ID of a Virtual Data Center.

• ip - (Required)[string] The reserved IP address to be used in the IP failover group.

• lan_id - (Required)[string] The ID of a LAN.

• nicuuid - (Required)[string] The ID of a NIC.

⚠ WARNING: Do not modify the IP for an IP failover group (that was provisioned via Terraform) using the DCD, the API or other means because it may lead to unexpected behavior. If you provisioned an IP failover group using Terraform, please use only Terraform in order to manage the created IP failover group.

⚠ WARNING: For creating multiple IP failover groups at the same time, you can use one of the following options:

1. Create multiple IP failover groups resources and use depends_on meta-argument to specify the order of creation, for example:

resource "ionoscloud_ipfailover" "firstexample" {
  datacenter_id         = <datacenter ID>
  lan_id                = <LAN ID>
  ip                    = <IP address>
  nicuuid               = <NIC UUID>
}

 resource "ionoscloud_ipfailover" "secondexample" {
   depends_on = [ ionoscloud_ipfailover.firstexample ]
   datacenter_id         = <datacenter ID>
   lan_id                = <LAN ID>
   ip                    = <IP address>
   nicuuid               = <NIC UUID>
 }

2. Define the resources as presented above, but without using the depends_on meta-argument and run the apply command using -parallelism=1 as presented below:

terraform apply -parallelism=1

Import

Resource IpFailover can be imported using the resource id, e.g.

terraform import ionoscloud_ipfailover.myipfailover {datacenter uuid}/{lan uuid}

A note on multiple NICs on an IP Failover

If you want to add a secondary NIC to an IP Failover, follow these steps:

1. Creating NIC A with failover IP on LAN 1

2. Create NIC B unde the same LAN but with a different IP

3. Create the IP Failover on LAN 1 with NIC A and failover IP of NIC A (A becomes now "master", no slaves)

4. Update NIC B IP to be the failover IP ( B becomes now a slave, A remains master)

After this you can create a new NIC C, NIC D and so on, in LAN 1, directly with the failover IP.

Please check examples for a full example with the above steps.
