This is the setup I use for managing my homelab. This is a forever work-in-progress and nothing should be considered to be production-ready or best practice.

5 bay (but only 2 works due to hardware failure) NAS running Armbian. |
| 3 | Raspberry Pi 4 Model B Rev 1.2 | 4 x ARM Cortex-A72 CPU @ 1.5 GHz 2 GB SDRAM |
Boards stacked in a cluster case. |
- Nomad and Consul cluster.
- 1 server running in an Ubuntu 22.04 VM on ESXi.
- 4 clients running in the Helios64 and Raspberry Pis.
Cluster configuration is done in layers. The bottom layer is handled by cloud-init to bootstrap the base operating system, create users, authorize SSH keys, and some other basic settings.
Next Ansible is used to apply more advanced configuration to the hosts.
Finally, Terraform is used for application-level configuration, such as creating Nomad and Consul ACL tokens.
