Please don't allow Terraform to delete the tags prefixed by "cit:" tags", or the "Cost Center" tag! They are important for the migration to the v2 Direct Connect architecture. If you (or Terraform) delete those tags, they will be recreated before the migration proceeds. Deleting the "Cost Center" tag on TGW attachments will result in customers paying for TGW attachment costs instead of CIT. |
This is what it looks like when Terraform finds those tags, and makes a plan to delete them:
...
| Code Block | ||
|---|---|---|

resource "aws_subnet" "example" {
cidr_block = "10.92.117.128/25"
vpc_id = aws_vpc.example.id
...
tags = {
Name = "example-subnet"
}
lifecycle {
ignore_changes = [
tags["cit:dc-arch-migration-description"],
tags["cit:dc-arch-migration-target"],
tags["cit:dc-arch-version"],
tags["cit:dc-vgw"],
tags["cit:subnet-type"],
tags["cit:tgw-attachment-target"],
tags["cit:tgw-attachment-guidance"],
tags["Cost Center"],
]
}
