In regulated enterprises, thousands of physical servers sit idle overnight, capacity paid for but unused. We built a spot scheduler that reclaims this donated infrastructure, turning idle bare-metal into ephemeral Kubernetes clusters using Cluster API and k0smotron. Each cluster runs Kata Containers and Confidential Containers (CoCo) for workload isolation and attestation, essential when running on hardware you don't permanently own.
Ephemeral clusters create an ephemeral DNS problem. As spot clusters spin up and down nightly, services must be discoverable without manual intervention. Bindy — an open-source, Rust-based Kubernetes operator for BIND9, closes the loop, automatically managing DNS records as clusters materialize and dissolve.
This talk covers the spot scheduler architecture, why CoCo and Kata are essential for multi-tenant spot workloads, and how bindy provides DNS lifecycle automation for ephemeral infrastructure.
