Note

Depending on the type of change you configure, resources could be updated in place, or destroyed an recreated. To avoid unexpected downtime or data loss, always review the changes planned by Terraform before approving them.

 The Terraform plan output logs list resources that which shall will be updated in-place will be clearly marked and listed separately from those which will be new newly added  or destroyed. The tilde character (~) is also used to flag resources that are that updated in place.flags resources and attributes that trigger an in-place update, for example:


Code Block
Terraform will perform the following actions:

  # module.web_server.openstack_compute_instance_v2.instance will be updated in-place
  ~ resource "openstack_compute_instance_v2" "instance" {
        id                  = "552f77d0-dc87-4de8-bc58-93c0b324761a"
      ~ image_name          = "Ubuntu 22.04 NVIDIA_AI" -> "ubuntu-22.04-20250604054912"
       # (16 unchanged attributes hidden)
