Deploy / build (push) Successful in 56s
perf(images): WebP banners, text-only related cards, resized list thumbnails
Measured before/after with headless Chrome + CDP (not by eye):

- article banner: <picture> WebP q78 with the PNG as fallback, because the PNG
  must stay for og:image (social scrapers do not reliably render WebP cards).
  70 banners: 6.02 MB -> 2.52 MB (42%). JPEG measured *larger* than PNG here
  (q85 = 129%) — the art is flat terminal-style with sharp text edges.
- post page related cards: dropped four 1200x630 PNGs (183 KB) to display
  526x276 where the embedded code is illegible; now text-only cards with a
  category badge, date and reading time.
- list thumbnails (home + archive): new /og/thumb/<name>-{400,800}.webp served
  via srcset/sizes. Rows display at ~398px but were pulling full 1200x630 PNGs.
  Homepage thumbnails ~450 KB -> 62 KB; archive (71 rows) ~3.2 MB -> 436 KB.
- desktop banner capped at 720px centred: 67% -> 45% of a 900px viewport,
  keeping the art intact instead of cropping it.

Post page totals: images 277 KB -> 38 KB; page height 5758 -> 5065 (desktop)
and 9423 -> 8807 (mobile). Build: 163 pages.

Script: scripts/optimize-images.py; policy: docs/design-guide.md §3; runbook

Ops & Deploy Runbook — blog.hoelee.com

How this blog is built, deployed, and kept alive. Read when debugging CI/CD, deployment, or hosting.


Pipeline

Markdown (src/content/posts) → Astro build (dist/) → Gitea Actions → act_runner on unRaid
  → nginx container → Cloudflare tunnel → Cloudflare CDN → blog.hoelee.com
  • Repo: git.hoelee.com/hoelee/hoelee-blog (push here first, then GitHub — standing convention).
  • Runner: act_runner on unRaid (verified working: Gitea 1.27.3 + runner 3.3.2, PAT-secret pipeline).

Write & publish a post

  1. Create src/content/posts/<slug>.md with frontmatter (see content-guide.md §6).
  2. Push to main.
  3. CI builds dist/ and deploys to the nginx container automatically.
    • Before pushing a post that adds art, generate its in-page derivatives: uv run --with pillow python scripts/optimize-images.py <slug> (banner .webp + /og/thumb/<name>-{400,800}.webp). The PNGs from banner-gen / og-gen remain the og:image source of truth — see design-guide.md §3 for the format policy and measured sizes.
  4. Verify live: curl -I https://blog.hoelee.com/<slug> → expect 200.

Build pitfalls (from prior Astro work — check these first)

  • No JSX helper components in frontmatter — inline JSX directly in .map() calls, or the build fails with Expected ">" but found "class".
  • Import depth — src/pages/*.astro use ../layouts/…; subdirs use ../../. Wrong level = Could not resolve.
  • Footer must render AFTER <main> — a shared header+footer component renders footer above content otherwise.
  • npm install scripts blocked can leave esbuild's binary missing → check npm warn install-scripts at install time.

Verify before shipping a layout change

Headless-Chrome screenshot + vision check on both 390px and 1280px:

CHROME="/c/Program Files/Google/Chrome/Application/chrome.exe"
"$CHROME" --headless --disable-gpu --window-size=1280,2400 \
  --screenshot="$(cygpath -w $LOCALAPPDATA/Temp/blog.png)" \
  --virtual-time-budget=4000 "http://localhost:4321/"

Overflow diagnosis (real numbers, not screenshot guessing): check scrollWidth > innerWidth via CDP Runtime.evaluate.


Hosting notes

  • Static output = trivial to serve from any nginx/OpenLiteSpeed dir. Cloudflare in front gives CDN + HTTPS + DDoS.
  • Cloudflare Pages git integration supports GitHub/GitLab only — not Gitea. Current setup (Gitea → self-hosted runner → nginx) sidesteps this entirely and is the reason the pipeline is the way it is.
  • Full self-hosting also avoids Cloudflare Pages' 25MB/file, 20k-files limits — a decision already baked into this architecture.

Health checks

  • curl -I https://blog.hoelee.com/ → 200, correct content-type.
  • curl https://blog.hoelee.com/sitemap.xml → lists all published posts.
  • curl https://blog.hoelee.com/rss.xml → non-empty.
  • DNS: blog.hoelee.com resolves through Cloudflare (proxy enabled).

Pitfall: premature poll caches a 16-day 404

The origin serves Cache-Control: max-age=1382400 (16 days), and Cloudflare caches negative (404) responses too. If you curl a freshly-deployed URL before the CI deploy finishes, Cloudflare caches that 404 for 16 days — the page itself returns 200 but its og/banner PNGs 404 with cf-cache-status: HIT.

  • Detect: the bare URL 404s but ?v=<timestamp> (cache-buster) returns 200 → origin is fine, edge cache is stale.
  • Fix: purge the Cloudflare zone cache. Zone-level token (Zone.Cache Purge perm, lives in the cloudflare-pages-deploy skill) → POST /zones/8c8b2359766ac853602b91dd851c630e/purge_cache with {"purge_everything":true}. See that skill for the exact curl.
  • Prevent: after git push, sleep ~60–90s before the first bare-URL check, or validate with ?cb=$(date +%s) first so you never register a 404 into edge cache.
