Monitoring
Grafana
Where I look when something feels slow: node health, disk pressure, backups, cert expiry.
Amsterdam · homelab
My own cloud.
My photos, files, documents and home automation, all running on my own hardware. Everything below is what that actually looks like.
Services
This is what is running.
Seven services doing the work I would otherwise rent. Each one replaced a subscription.
Files
Nextcloud
Files, calendars and contacts on every device I own. This one replaced Dropbox.
Photos
Immich
Every photo and video off my phone, on my own disks instead of Google Photos.
Home automation
Home Assistant
Lights, sensors and switches, automated locally. Nothing stops working when the internet does.
Single sign on
Authentik
Single sign-on for everything here, so there is one place to revoke access.
Storage
TrueNAS
The bulk storage behind everything else. ZFS on spinning disks, snapshotted.
My dashboard
Homepage
One page linking every service above, with a live status light on each.
Software
All of it runs on Kubernetes.
Two Talos nodes, one cluster. Argo CD is the only thing that touches it, so merging a pull request is the deploy.
What the cluster is made of.
- Talos Linux Immutable node OS
- Argo CD Applies what Git says
- Renovate Opens update PRs
- Envoy Gateway Ingress and routing
- MetalLB LoadBalancer IPs
- ExternalDNS DNS from manifests
- Cloudflare Tunnel, no open ports
- Longhorn Persistent volumes
- CloudNativePG In-cluster Postgres
- VolSync Scheduled backups
- Garage S3 for backups
- Authentik Single sign-on
- Bitwarden Stores the secrets
- External Secrets Pulls secrets into the cluster
- Prometheus Metrics and alerts
- Grafana Dashboards
- VictoriaLogs Log storage
- Fluent Bit Log shipping
Hardware
On my own hardware.
No rented server anywhere in this. Ten units of aluminium extrusion, with 3D-printed trays for whatever never came with rack ears.
What is in it.
- 10U Patch panel Twelve keystone ports
- 9U Router UniFi Express 7
- 8U Node 2 · Talos Blackview MP-80, stripped out of its case onto a printed tray
- 7U Switch UniFi Flex 2.5G, eight ports
- 6U Home Assistant BMAX B2 Pro, on its own box
- 5–4U NAS ODROID-H4+ · ZFS on the drives below
- 3U Disks Two 6 TB drives, hot swappable
- 2–1U Node 1 · Talos MINISFORUM UN1245 · i5-12450H · 16 GB
Power, one module at a time.
No power strip fits a 10-inch rack, so the back of it is printed too. It is a stack rather than a strip: every box brings its own module up with it, and nothing else in the rack changes.
- One per box Its own switch, so a box can be cut without reaching for anything else
- Chained A 30 cm cord from each module to the one below, so one cable leaves the rack
- Same face plate A C14 inlet, an illuminated rocker and a C13 outlet, whatever sits behind it
- Two variants A DIN rail socket for wall plugs, or a right-angle C13 onto the power brick
- 10U
- 220 × 240 × 445 mm
- 2020 extrusion, slot 6
- €75 in parts
- 3D-printed mounts
- CERN-OHL-S
