If your Terraform version doesn't allow you to name specific tags, you can tell it to ignore all tag changes: | Code Block |

lifecycle {
ignore_changes = [ tags ]

| Warning |
|---|
You must be using Terraform version 0.14.1 or later to specify specific tags (i.e. tags["just-this-tag"] ) in the ignore_changes attribute. If you are using any Terraform version prior to that, you will have to tell Terraform to ignore changes to all tags:| Code Block |

lifecycle {
ignore_changes = [ "tags" ]
} |
