Small Homelab

hardware

• 3 mini PCs with i7-8550U on each of them.
• each with 16 gigs of RAM and 512 SSD.
• tp-link 108SE 8-port gigabit managed switch.
• a raspberry pi for router (openwrt)
• a dumb tp-link AP which is segregated via VLAN.

tech stack

• proxmox is running on all nodes (at this point, who doesn’t use proxmox?)
• VMs are running ubuntu 22.04.
• k3s is used for running the services with 3 master VMs and 6 slave VMs across the proxmox cluster.
• a simple NFS storage is attached to k3s as a PVC. it’s not redundant and needs a lot of work.
• tailscale for accessing services from outside. i am considering selfhosting headscale instead in the future.
• ansible for managing most of the VM upgrade, running k3s updates, etc.
• PBS and restic for backups.

services (very few for now)

• musikcube for music
• emulatorjs for retro games
• calibre-web for books
• pi-hole DNS
• markdown + mkdocs for docs
• and a few other services.

future goals

• in progress of hosting a ton of remote and public services (mostly from a rented server)
• use LUKS for encrypting the drives but it will definitely affect perf
• use terraform for a full spin up of infrastructure at any time
• improve the security of homelab by properly configuring VLANs, using gvisor, removing tailscale, regular updates, etc
• robust monitoring
