Replicating BlumeOps

Audiences: Replicator

This tutorial provides a roadmap for building your own homelab GitOps environment inspired by BluemeOps. It links to detailed component tutorials for each major piece.

What You’ll Build

By following this guide, you’ll have:

  • A secure mesh network connecting your devices
  • A Kubernetes cluster for running containerized services
  • GitOps-driven deployments via ArgoCD
  • Observability with metrics, logs, and dashboards
  • Backup and disaster recovery capabilities

Hardware Requirements

BluemeOps runs on modest hardware. At minimum:

ComponentBlumeOps UsesMinimum Alternative
ServerMac Mini M1Any machine with sufficient RAM (16GB recommended)
NASSynology DS920+USB drive or second machine
WorkstationMacBook Air M4Whatever you use daily

You can start with a single machine and add storage later.

The Journey

Phase 1: Networking Foundation

Before deploying services, establish secure connectivity.

Setting Up Tailscale

  • Create a tailnet and connect your devices
  • Configure ACLs for service access
  • Set up MagicDNS for convenient naming

This replaces: traditional VPNs, port forwarding, dynamic DNS

Phase 2: Core Services

Bootstrap the essential services that everything else depends on.

Core Services Setup

  • Set up forgejo for git hosting and CI/CD
  • Optionally set up zot container registry
  • Configure SSH access and deploy keys

Forgejo is central to GitOps - it’s where your infrastructure definitions live and where CI/CD workflows run.

Phase 3: Kubernetes Cluster

A cluster for running containerized workloads.

Bootstrapping Kubernetes

  • Install minikube (or k3s, kind, etc.)
  • Configure persistent storage
  • Expose the API securely via Tailscale

BlumeOps uses minikube for simplicity, but the patterns apply to any distribution.

Phase 4: GitOps with ArgoCD

Declarative, git-driven deployments.

Configuring ArgoCD

  • Install ArgoCD in your cluster
  • Connect to your git repository
  • Deploy your first application
  • Set up the app-of-apps pattern

This is the heart of GitOps - changes in git automatically sync to your cluster.

Phase 5: Observability Stack

Know what’s happening in your infrastructure.

Building the Observability Stack

  • Deploy Prometheus for metrics
  • Deploy Loki for logs
  • Deploy Grafana for dashboards
  • Configure Alloy for collection

Without observability, you’re flying blind.

Phase 6: Your First Services

With the foundation in place, deploy actual workloads. BluemeOps runs:

Pick what matters to you. Each service follows similar patterns:

  1. Create Kubernetes manifests
  2. Create ArgoCD Application
  3. Configure ingress routing
  4. Sync and verify

Phase 7: Backups and Resilience

Protect your data.

  • Set up borgmatic for backup automation
  • Configure NAS as backup target
  • Test restore procedures
  • Document disaster recovery

Alternative Approaches

BluemeOps makes specific choices that may not suit everyone:

BlumeOps ChoiceAlternative
macOS serverLinux server (more common)
Minikubek3s, kind, or managed K8s
TailscaleWireGuard, Nebula
ArgoCDFlux, manual kubectl
AnsibleNixOS, Docker Compose

The principles (GitOps, IaC, observability) matter more than specific tools.

Getting Started

Begin with tailscale-setup - networking is the foundation everything else builds on.
