Terraform: terraform-openstack-srv_noportsec

TODO: CHECK THE FOLLOWING DESCRIPTION

Creates a virtual machine without portsec enabled. If you need a need a counter, please use "terraform-openstack-srv_noportsec-count" instead.

This module allows you to input image, network and subnet (including as part of the networks and additional_networks maps) configurations either as name or UUIDs. UUIDs will be used directly as input for the underlying resources and names will first be resolved to UUIDs using data sources. UUIDs are identified using a regular expression meaning that names which are UUID strings will not be recognized as names. This feature can be disabled using by setting the following boolean flags to false:

allow_network_uuid
allow_subnet_uuid
allow_image_uuid

Once disabled all input for the input type (e.g., network) will be considered to be names regardless of the UUID regular expression.

Networks configured via the networks input are considered as inherent parts of the created server instances. Thus any configuration changes resulting in the removal or addition of new ports (created from networks) will also force the recreation of the server instance. In contrast networks configured via additional_networks are attached to server instances after they have been created. The relationship between the two is thus weaker, meaning removal and addition of new additional_networks do not result in the recreation of the server instance. They just attach or detach the created network ports. Note that this also means networks configured through the additional_networks input cannot be guaranteed to be available during the instance boot (i.e., cloud-init). Thus brining the resulting network interfaces online in the operating system layer and configuring them must be handled separately from the terraform provisioning.

Note that for the image input it is not possible to use outputs from resources to assign a value to the input (e.g., using an image resources and then referencing the resulting id). Doing so will result in an error and planning/applying will only be possible after the referenced resource has been deployed using the terraform -target option.

Configuration

  image = var.image
  flavor = var.flavor
  config_drive = var.config_drive
  sshkey = var.sshkey
  network = var.network
  subnet = var.subnet
  userdatafile = "${path.module}/scripts/default.yml"
}
