# file: dns-entry.yml

# This playbook is used to create a DNS entry for a given server if it's IP address is a host variable.
# It will create a Terraform file in the homelab/terraform/dns directory.
# It will then run the Terraform apply command to create the DNS entry.
# It will then notify the update-dns handler to update the DNS entry.

# Future work:
# - Add a check to see if the DNS entry already exists.
# - Add a check to see if the Terraform provider is already configured.
# - Add a check to see if the Terraform DNS entry is already created.
