Bart Van Geyt 9f819df4d9 Phase 0: architecture docs, ADRs, and repo scaffold
Establish the design foundation for the heleosv2 multi-tenant hosting
platform before any implementation code:

- Monorepo skeleton: docs/, platform-infra/, site-templates/,
  deployments/, control-panel/ with orientation READMEs.
- docs/: roadmap index, architecture + threat model, naming conventions,
  site profiles, provisioning workflow, backup & DR runbook, repo/GitOps
  layout, and the approved architecture plan.
- docs/adr/: 9 ADRs recording the rationale for single-host Compose,
  Traefik edge, nginx+fpm split, shared MariaDB, ZFS-per-customer,
  decoupled backup streams, Forgejo, CLI-first, and SFTP-only.
- Secrets hygiene: .gitignore (only *.enc.* committed) and .gitattributes
  (LF for scripts/Dockerfiles/YAML run on the Linux host).

heleosv2 — Multi-Tenant Web Hosting Platform

A rebuild of a small web-hosting business on modern, isolation-first infrastructure: container-per-customer + ZFS-dataset-per-customer, with repeatable CLI-driven provisioning and clean per-customer backup/restore.

Core philosophy — the customer is the boundary. Isolation (containers), backup (ZFS), and restore all line up on the same boundary, so a compromised or broken site is contained and restorable without touching neighbours.

Status

Phase 0 — writing the design documents before any platform code. See docs/00-roadmap.md.

Repository layout

This monorepo groups four logical areas whose contents have different lifecycles (see docs/07-repo-layout-gitops.md):

Path Purpose
docs/ Architecture, ADRs, runbooks, conventions.
platform-infra/ Ansible + base compose for host, Traefik, MariaDB, Forgejo, monitoring.
site-templates/ Dockerfiles for standard images + compose templates per site profile.
deployments/ Rendered per-customer configs (GitOps state). No plaintext secrets.
control-panel/ Provisioning CLI now; customer-facing panel later.

Key decisions

  • Single bare-metal host, Docker Compose per customer, no orchestrator.
  • Shared MariaDB (per-site DB + least-privilege user).
  • Decoupled backups: web files via ZFS snapshot/send; DB via automysqlbackup + rsync; logs via Loki.
  • Lightweight DevOps: Forgejo + built-in registry + Trivy.
  • CLI-first provisioning; web panel deferred until the platform is proven.

The full approved architecture plan lives at docs/architecture-plan.md.
