Growing the Cluster: Adding rock5, rock6, and rock7 to Bletchley
Three new RK1 worker nodes, three different Longhorn disk problems. The right way to add a node — and what happened when I didn't follow it.

Keeping the Bletchley Cluster Current: Talos, Kubernetes, and Every Helm Chart
Upgrading Talos, Kubernetes, and thirteen Helm charts with real workloads running — the safe order, the tools, and what went wrong. The how, not the what.

Backup Controller v0.11.0: Detecting What Wasn't Created by the Controller
The controller managed its own backups perfectly. It had no idea about the rest. v0.11.0 adds an audit script and two new alert conditions to close that gap.

stern: Real-Time Log Tailing Across Your Kubernetes Cluster
stern tails logs from multiple Kubernetes pods at once. I used it to find a pending Traefik upgrade and reconstruct a PVC resize across five pod types.

Closing the Backup Loop: A Custom Controller for Longhorn
New PVCs were silently unprotected until I noticed. I built a label-driven controller to close the loop — jobs created automatically, violations alerted, archives handled.

k9s: A Terminal UI for Navigating Your Kubernetes Cluster
k9s gives you an interactive terminal UI for your Kubernetes cluster. I installed it and immediately found a backup job that had been silently failing for eleven days.

Cluster Observability Part 3: Dashboards for Storage, Kubernetes, and Network
Importing Longhorn, Kubernetes, and resource dashboards onto the Bletchley cluster — and fixing the scrape config that was only collecting from one of four nodes.

Backup Validation: Restoring from Longhorn Backups
Testing the backup chain: etcd encryption with age, and a full Grafana PVC delete-and-restore to confirm Longhorn backups actually work.

Backup Infrastructure: Garage S3, ZFS, and Longhorn Backup Targets
Building the local backup layer for the Bletchley cluster: ZFS mirror on rock3's SATA SSDs, Garage S3, NFS, and Longhorn recurring backups.

Longhorn Deep Dive: Replicas, Versions, and Upgrades
The decisions behind the Longhorn installation: why 2 replicas on a 1Gb cluster, how version pinning protects reproducibility, and when to upgrade.
