gates / gates (push) Successful in 21s
hub v0.100.0 — the Configuration page took 26 seconds, and it was never hashing anything
MEASURED, NOT GUESSED: GET /configuration -> HTTP 200 in 26.2s.

The reasonable guess was that it hashes the artifacts on page load. It does not, and the code already
said so: Gitea stores each package file's sha256 and gitea.FileSHA256 reads it as metadata — "a cheap
metadata call, the artifact bytes are never downloaded". The cost was never CPU.

IT WAS LATENCY x COUNT. artifactChoices made ONE SERIAL round-trip per version, for two packages,
capped at 20 each: 2 x (1 version list + 20 sha lookups) = 42 sequential requests at ~0.6s each out
through the public ingress. 42 x 0.6 = 26s, which is what the clock said.

1. The sha lookups now run CONCURRENTLY, bounded at 8 in flight. Order preserved by writing into a
   slot rather than appending — the dropdown is newest-first, and a scrambled sha would show the
   operator a hash belonging to a DIFFERENT artifact. A failed lookup still drops that version only.
2. The client talks to Gitea IN-CLUSTER (http://gitea.gitea-system.svc.cluster.local:3000,
   overridable via GITEA_API_URL). Measured from the hub pod: 0.11s against 0.26-1.16s, because the
   public path adds DNS, the ingress hop and a TLS handshake to each of the 42. Plain HTTP is safe
   ONLY because it never leaves the cluster network — the registry token rides the Authorization
   header, so this must not point at a public host without TLS. Unreachable -> the existing graceful
   degradation to manual text entry, unchanged.

DELIBERATELY NOT DONE: caching the sha in the hub's own database. That was the other half of the
proposal and it is the wrong shape. Gitea already IS the store; a copy in hub_settings would be a
second source of truth that can drift from the registry it describes — and the operator reads exactly
this value to confirm what they are about to vouch, so a stale one would be a confident wrong answer.
The same reasoning golden_currency_gate.py already records for the vouched version. With the fan-out,
a cold load needs no cache to be fast.

The cap stays at 20 and now bounds the FAN-OUT too, not just the rendered list.

Tests pin order (and that each sha belongs to its own version), per-version failure isolation, and
THE CONCURRENCY ITSELF — a wall-clock assertion plus an in-flight counter, so a fast run cannot be
luck, and an upper bound so a large package list cannot stampede Gitea. Red-proof: reverting to the
serial loop takes 861ms where the concurrent one takes 150ms, and the test fails naming the
26-second page.

felhom.eu

Website, manifests, and infrastructure for Felhőm.eu — a managed home-server service for Hungarian households.

Overview

This repository contains:

  • Website (website/) — Static HTML pages served at felhom.eu
  • Kubernetes manifests (manifests/) — All k3s deployments for the felhom.eu ecosystem
  • Assets (website/assets/) — Logo, images, OG images

The website runs on a single-node k3s cluster alongside the rest of the Felhőm management infrastructure (Healthchecks, Umami analytics, contact mailer).

Branding

Aspect Value
Brand name Felhőm.eu (with accent: ő)
Domain felhom.eu (without accent — domain limitation)
Tagline „Saját felhőd, saját szabályaid"
Controller product Felhő Felügyelő (customer-facing name)
Controller code name felhom-controller (backend/repo/container)
Language Hungarian throughout all customer-facing content
Contact email info@felhom.eu
Admin email admin@felhom.eu

Why "Felhőm"?

"Felhő" means "cloud" in Hungarian. The "m" suffix makes it possessive — "my cloud" (felhőm). The .eu domain is part of the brand identity and appears in the logo. The double meaning of "felhő" (tech cloud + weather cloud) is intentional and used in product naming (e.g., Felhő Felügyelő = "Cloud Supervisor/Inspector").

Website Pages

File URL Purpose
index.html / Landing page — hero, services, app preview, backup intro, contact
alkalmazasok.html /alkalmazasok Full application catalog (45+ apps with categories)
technologiak.html /technologiak Technology stack explanation (Docker, Felhő Felügyelő, Proxmox, Kubernetes)
biztonsagimentes.html /biztonsagimentes Backup strategy — 3-2-1 rule, monitoring, restore procedures
gyik.html /gyik FAQ — structured Q&A with JSON-LD schema
kapcsolat.html /kapcsolat Contact form + email, sends via contact-mailer API
szolgaltatasok-nonpublic.html /szolgaltatasok-nonpublic Pricing/services page (not linked in nav, robots disallowed)

All pages use:

  • Clean URLs — nginx serves .html files without extension (/gyikgyik.html)
  • Unified CSS — each page contains the full CSS (no external stylesheet, for simplicity)
  • Responsive design — mobile hamburger menu, responsive grids
  • UTF-8 with BOM — all HTML files are saved as UTF-8-BOM for Hungarian character support
  • Umami analytics — privacy-friendly tracking script on every page

Kubernetes Manifests

Manifest Services Subdomains
webpage.yaml nginx (website), FileBrowser, git-sync felhom.eu, www.felhom.eu, files.felhom.eu
contact-mailer.yaml Go HTTP server for contact form felhom.eu/api/* (path-based routing)
umami.yaml Umami v3 + PostgreSQL stats.felhom.eu
healthchecks.yaml Healthchecks status.felhom.eu

Website Deployment

The website uses a git-sync sidecar pattern:

  1. git-sync container polls this repository (sparse checkout: /website/ only)
  2. Syncs to a shared emptyDir volume
  3. nginx container serves from the synced content
  4. Changes pushed to this repo are live within minutes (no manual deployment)

FileBrowser at files.felhom.eu provides a web UI for quick edits to website files (emergency fixes, asset uploads) without needing git. It writes to a Longhorn PVC that the website nginx also reads from.

Storage

All persistent data uses Longhorn distributed storage:

  • filebrowser-files (1Gi, ReadWriteMany) — website files
  • filebrowser-db (100Mi) — FileBrowser SQLite database
  • umami-db-data (2Gi) — Umami PostgreSQL data
  • healthchecks-data (1Gi) — Healthchecks SQLite data

DNS Configuration (Cloudflare)

Domain: felhom.eu — Cloudflare DNS (free plan), DNS only mode (no proxy/orange cloud).

Email

Incoming Email

Cloudflare Email Routing (free) handles all incoming mail:

  • info@felhom.eu → forwarded to personal Gmail
  • admin@felhom.eu → forwarded to personal Gmail
  • Catch-all → not configured

Outgoing Email (Transactional)

Resend (free tier) handles outgoing email via API:

  • Contact form submissions → sends formatted email to info@felhom.eu
  • Healthchecks alerts → sends to admin@felhom.eu
  • Sending domain: send.felhom.eu (verified with SPF, DKIM)
  • From address: Felhom.eu <info@felhom.eu>

Contact Form Flow

  1. User fills form on /kapcsolat
  2. JavaScript POST to /api/contact
  3. contact-mailer (Go, in k3s) validates + calls Resend API
  4. Email delivered to info@felhom.eu via Resend → Cloudflare Email Routing → Gmail

  3. Changes are live immediately

Standard workflow

  1. Clone this repo from Gitea (gitea.dooplex.hu)
  2. Edit files locally
  3. Push to main branch
  4. git-sync sidecar picks up changes automatically (~1-2 min)

Adding a new page

  1. Create website/newpage.html (copy structure from existing page)
  2. Add to navigation in all pages' <nav> section
  3. Add to sitemap.xml with appropriate priority
  4. Push — clean URLs handle /newpage automatically
Repository Purpose
app-catalog-felhom.eu Docker Compose templates + .felhom.yml metadata for 45+ apps
felhom-controller felhom-controller Go app + customer deploy scripts
deploy-portainer Legacy — Portainer-based deploy scripts (deprecated)
homelab-manifests k3s cluster manifests for dooplex.hu services
misc-scripts Utility scripts (collect-repos.sh, etc.)

File Encoding

All HTML files in website/ are UTF-8 with BOM (byte order mark). This ensures proper Hungarian character rendering (á, é, í, ó, ö, ő, ú, ü, ű) across all tools and platforms. The BOM is the 3-byte sequence EF BB BF at the start of each file.

When editing files, ensure your editor preserves UTF-8-BOM encoding. VS Code: check "UTF-8 with BOM" in the bottom status bar.
