Bart Van Geyt d715244b76 Phase 1: Ansible host baseline for Ubuntu VM 
Idempotent host configuration targeting Ubuntu 24.04 with ZFS on a
dedicated second disk. Role-based platform-infra/ansible:

- base: apt packages, timezone, unattended security upgrades.
- zfs: install ZFS, create pool on a dedicated disk (guarded against
  wiping a non-empty disk), create platform datasets + customers parent
  per docs/03; docker dataset mounted at /var/lib/docker.
- docker: Docker Engine + Compose plugin, daemon.json written before first
  start so the native zfs storage driver initializes on the ZFS data-root;
  per-site network address pool preconfigured.
- firewall: nftables inbound default-deny in a dedicated table that never
  flushes Docker's rules; container outbound SMTP blocked via a DOCKER-USER
  jump applied by a systemd oneshot.
- ssh_hardening: key-first SSH with an anti-lockout assertion, config
  validation gate, and the sftponly group for Phase 4 SFTP accounts.

Includes ansible.cfg, requirements.yml, inventory example, group_vars with
safety notes, and a run guide. Real inventory (hosts.yml) is git-ignored.

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.
