blumeops

aka "Blue Mops"

Tools and configuration for Erich Blume's personal infrastructure, orchestrated across a Tailscale tailnet.

This is a homelab, but it's also a testing ground for AI-assisted infrastructure development. Much of this codebase was co-authored with Claude Code, and the repo places heavy emphasis on documentation, process, and change classification to make that collaboration work well. I don't know entirely how I feel about LLMs in our current era (there are real concerns about how training data is sourced and energy subsidy) but it felt important to learn how to work with these tools.

The full documentation is published at docs.eblu.me and lives in the docs/ directory, structured around the Diataxis framework and designed to be compatible with Obsidian/Obsidian.nvim.

What runs here

Services are a mix of Kubernetes pods (managed by ArgoCD), macOS LaunchAgent services (managed by Ansible), and NixOS systemd services (managed by Nix flakes), all connected via Tailscale:

• Indri (Mac Mini M1) - primary server. Most services run in Minikube via ArgoCD; Forgejo, Caddy, and others run natively as LaunchAgent services via Ansible.
• Ringtail (NixOS desktop, RTX 4080) - GPU workloads (Frigate NVR, Authentik SSO) on k3s, plus NixOS systemd services.
• Sifaka (Synology NAS) - backup target and bulk storage.

Notable services include Grafana/Prometheus/Loki observability, Immich photos, Jellyfin media, Forgejo git forge, a Zot container registry, and more. Public access is routed through a Fly.io proxy; everything else is tailnet-only.

Getting started

You'll need Homebrew and mise:

brew bundle                    # install CLI tools (argocd, tea, flyctl, etc.)
mise install                   # install managed toolchains (ansible, pulumi, dagger, etc.)
prek install                    # set up git hooks

Git hooks (via prek) enforce secret scanning (TruffleHog), linting, formatting, and custom checks like doc link validation and the Mikado branch invariant. They run automatically on git commit.

Operational tasks are driven through mise. Run mise tasks to see what's available. Key examples:

mise run provision-indri       # deploy to indri via Ansible
mise run services-check        # verify service health
mise run container-list        # list tracked container images

AI-assisted development

This repo is designed to be worked on by both humans and AI agents. The CLAUDE.md file provides instructions for Claude Code, and the docs/tutorials/ai-assistance-guide.md explains the full workflow.

Changes are classified before starting work:

• C0 - quick fixes, committed directly to main
• C1 - feature branch + PR, documentation written before code
• C2 - multi-phase work using the Mikado method for dependency tracking

See the agent change process for details.
