> **Infrapuzzle** is the monorepo for my personal infrastructure, encompassing Kubernetes cluster provisioning, workload deployment, DNS management, and IoT monitoring.
## Repository Structure & Documentation
This repository is divided into distinct domains, each with its own `AGENTS.md` or specialized documentation.
### 1. [Bootstrap](./bootstrap/AGENTS.md) (`bootstrap/`)
* **Purpose**: Provisioning the single-node Kubernetes cluster (Haumdaucher).
* **Tool**: Kubespray (Ansible).
* **Key File**: `init.sh` (Source of Truth for versioning).
* **Read**: [bootstrap/AGENTS.md](./bootstrap/AGENTS.md)
### 2. [Kubernetes Workloads](./k8s/AGENTS.md) (`k8s/`)
* **Purpose**: Deploying applications and services to the cluster.
* **Strict Namespace Rule**: **Every top-level subdirectory in `k8s/` strictly corresponds to a Kubernetes namespace.** Non-namespace folders, loose scripts, or documentation do not belong here.
* **Constraints**: Enforces `ingress-nginx` / `traefik`, `cert-manager` (Let's Encrypt), and `git-crypt` for secrets.
* **OpenClaw**: For OpenClaw AI agent deployment and troubleshooting, see [k8s/openclaw/AGENTS.md](./k8s/openclaw/AGENTS.md) and [k8s/openclaw/TROUBLESHOOTING.md](./k8s/openclaw/TROUBLESHOOTING.md).
* **Read**: [k8s/AGENTS.md](./k8s/AGENTS.md)
### 3. Terraform (`terraform/`)
* **Purpose**: Infrastructure as Code divided into two symmetrical modules:
* **Cloud & DNS (`terraform/infrastructure/`)**:
* **DNS Zones**: `haumdaucher.de`, `moritzgraf.de`, `ameliegraf.de`, and others via OVH (`ovh/ovh`).
* **Cloud Services**: Authentik SSO (`authentik.tf`), GCP APIs, backups, and Google Workspace MX/SPF/DKIM.
* **Usage**: `cd terraform/infrastructure && terraform apply`
* **Smart Home Shelly Automation (`terraform/shelly/`)**:
* **Taupi Cellar Mold Ventilation**: Automates Shelly Plug S with psychrometric dew point calculations (`Taupi-4.0.js`) and BTHome Bluetooth sensor telemetry.
* **Usage**: `cd terraform/shelly && terraform apply`
* **Read**: [terraform/shelly/AGENTS.md](./terraform/shelly/AGENTS.md)
### 4. Monitoring (`monitoring/`)
* **Purpose**: Physical ambient BLE sensor fleet monitoring across living areas.
* **Tool**: [ESPHome](https://esphome.io).
* **Devices**: Temperature & humidity sensors, Xiaomi BLE plants, ESP32 bridges (`muc-kitchen`, `muc-living`, `rgbg-living`).
* **Usage**:
```bash
cd monitoring
esphome run config/<device>.secret.yml
```
* **Read**: [monitoring/README.md](./monitoring/README.md)
### 5. Knowledge Wiki & OpenClaw Tasks (`knowledge-wiki/`)
* **Purpose**: Shared personal knowledge wiki and task dispatch between OpenClaw (mobile/Telegram concierge) and Antigravity (local pair programming agent).
* **Location**: Git submodule `knowledge-wiki/` at root of `infrapuzzle` (Git repo: `https://git.moritzgraf.de/moritz/knowledge-wiki.git`, branch `main`).
* **Queue File**: `knowledge-wiki/tasks/antigravity.md`.
* **Workflow for Antigravity**:
- When the user asks to check tasks or pick up work from OpenClaw:
1. Pull latest: `git submodule update --remote knowledge-wiki` (or `git -C knowledge-wiki pull --rebase origin main`)
2. Read `knowledge-wiki/tasks/antigravity.md` to see pending items.
3. Implement the chosen task in the appropriate repository files.
4. Move the task to `## ✅ Completed Tasks` with completion details and commit info.
5. Push back: `git -C knowledge-wiki commit -am "chore(tasks): complete <task>" && git -C knowledge-wiki push origin main`.
### 6. Architecture Decision Records (`docs/adr/`)
* **Purpose**: Formal record of architectural decisions, technical trade-offs, and design standards across the monorepo.
* **Format**: [MADR](https://adr.github.io/madr/) (Markdown Architectural Decision Records).
* **Consulting ADRs**: AI agents MUST consult `docs/adr/` before designing or altering system architecture, agent topologies, or tool integration patterns.
* **Key Records**:
* [ADR 0001: Hybrid MCP Tool Search and Subagent Delegation for AI Agents](docs/adr/0001-hybrid-mcp-tool-search-and-subagents.md)
* [ADR 0002: OpenClaw Multi-Tier Model Selection, Latency Optimization, and Inference Economics](docs/adr/0002-openclaw-model-selection-tiering-and-economics.md)
* [ADR 0003: Everything as Code (EaC) and Reproducible Declarative Infrastructure](docs/adr/0003-everything-as-code-and-reproducible-infrastructure.md)
