Kubernetes Cluster
BlumeOps runs a single Kubernetes cluster: k3s on ringtail, managed by argocd running in-cluster. (Until 2026-06 a minikube cluster on indri hosted most services — retired in retire-minikube.)
Cluster Specifications
| Property | Value |
|---|---|
| Distribution | k3s (single node) |
| Context | k3s-ringtail |
| API Server | https://ringtail.tail8d86e.ts.net:6443 |
| Architecture | x86_64, RTX 4080 GPU |
See ringtail for host specs, the workload list, and secrets management.
Volume Mounting
Stateful workloads use the local-path storage class (node-local).
Media and bulk data mount NFS directly from Sifaka — see
sifaka-nfs-from-ringtail.
Images
Workload images are locally built (Nix, amd64, -nix tags) and pulled
from zot at registry.ops.eblu.me. A handful of infrastructure
images (argocd, cnpg, external-secrets, 1password-connect) remain
pinned upstream multi-arch — tracked by the local-registry compliance
task.
