Before any of this became a k3s homelab, the fleet ran on Oracle Cloud free-tier instances provisioned by two Terraform repos — `oci-terraform-network` (VCN, subnet, security rules, an internet gateway, block storage) and `oci-terraform-cluster` (compute instances, including a later ARM instance) — with `oci-product-service`'s Ansible playbook handling the actual deployment: installing dependencies, running the Docker-based services, and updating Cloudflare DNS records on every deploy.
