rpi-cloud-init

This repository supports the initialization of my at-home cloud.

My goal is to build a modular, relatively low-power system.

Hardware

• 1x 2013 Apple Mini
  • Operating System / Architecture: Ubuntu 20.04 / amd64
  • Specs: 8 CPU, 16GB RAM, 512GB Disk (eventually 1TB)
  • Media:
    • 512GB flash drive (USB 3.0)
  • Services: MinIO, k3s (server)
• 3x Raspberry Pi 4
  • Operating System / Architecture: Ubuntu 20.04 / arm64
  • Specs: 4 CPU, 4GB RAM, 32GB Disk
  • Media:
    • 512GB flash drive (USB 3.0)
  • Services: CockroachDB
• 8x Raspberry Pi 3b+
  • Operating System / Architecture: Ubuntu 20.04 / arm64
  • Specs: 4 CPU, 1GB RAM, 32GB Disk
  • Services: k3s (agent)

Cluster

• Provisioning
  • cloud-init - Machine initialization
  • terraform - Declarative provisioning
  • cert-manager - Certificate management
• Storage
  • CockroachDB - Relational database management system
  • MinIO - Erasure coded, small-blob storage
• Compute
  • docker / docker-machine - Containerization (deprecate)
  • k3s - Extendable compute cluster
  • To do:
    • containerd - Containerization
• Observability
  • prometheus - Data collection and storage
  • grafana - Data visualization

Workloads

• services - Aliases for out-of-cluster services
• redis - General purpose, caching solution
• homestead - Index builders that help manage my homestead
• varys - Secret engine and privileged access management
