Case Study: ToThePoint achieves immutable, automated Raspberry Pi infrastructure with HashiCorp Nomad, Consul, and Packer

A Keyboard Wall That Showcases Immutable Infrastructure as Code With Nomad

ToThePoint, a Belgium-based IT consultancy, built a large RGB keyboard wall for demos and experimentation, but their early setup was fragile and hard to operate at scale. As the project grew from a handful of keyboards to 54 keyboards across 27 Raspberry Pis, they needed a simpler way to manage diverse workloads, automate deployments, and recover quickly from hardware or process failures without relying on Kubernetes.

ToThePoint used HashiCorp Nomad, along with Consul and Packer, to turn the wall into an immutable, infrastructure-as-code environment. HashiCorp Nomad scheduled controller processes across the Raspberry Pis, while Packer helped create reusable ARM images and Consul supported service discovery; the team also added Ansible, MinIO, and a private Docker registry to streamline updates and offline deployments. The result was a more reliable, portable system that could be rebuilt quickly, replaced node-for-node, and operated without internet access, though the case study does not provide specific quantitative performance metrics.
