Universal Blue uCore homelab infrastructure with Terraform/Pulumi cloud management

📖 Overview

This is a monorepo to manage my personal homelab infrastructure. Running Universal Blue uCore (Fedora CoreOS-based immutable OS) on the main host ("mouse") with Terraform/Pulumi for cloud resource management. The infrastructure provides object storage (RustFS), monitoring (Netdata), and backup capabilities (Backblaze B2).

🔧 Infrastructure Components

🔵 uCore

Universal Blue uCore provides immutable, container-first host configuration. Configuration in infra/ucore/ using Butane → Ignition.

• uCore Overview
• Container Architecture
• Deployment Strategies

Entry point: infra/ucore/butane/

☸️ Kubernetes (k0s)

Single-node k0s cluster planned for mouse. Configuration managed via k0sctl.

• Kubernetes on uCore

Entry point: infra/k0s/

🌐 Terraform

Terraform manages cloud resources (maintenance mode — migrating to Pulumi):

• Cloudflare: DNS and domain management (infra/terraform/cloudflare/)
• Backblaze B2: Backup storage provisioning (infra/terraform/backblaze/)
• Terraform Cloud: Workspace management (infra/terraform/tf-cloud/)

🚀 Pulumi

Pulumi stubs created for migrating cloud resources from Terraform (Go-based):

• Backblaze: B2 provisioning (infra/pulumi/backblaze/) — has initial Go code
• Cloudflare: DNS management (infra/pulumi/cloudflare/) — stub
• Terraform Cloud: Workspace management (infra/pulumi/tf-cloud/) — stub

🔐 SOPS

Age-based secrets management for encrypting sensitive configuration values inline with repository files.

🖥️ Current Host

mouse (uCore)

Primary infrastructure host running:

• Storage: ZFS pools
• Object Storage: RustFS (S3-compatible, Rust-based)
• Monitoring: Netdata for system metrics

Configuration: infra/ucore/butane/hosts/mouse.bu

🌐 Cloud Integrations

Cloudflare

DNS and domain management for multiple domains (familylegacy, legacy, prof, public zones)

Backblaze B2

S3-compatible backup storage for long-term data retention
