+# PRD — Portfolio gosambi.uk
+
+> Website portofolio statis untuk gosambi.uk dan www.gosambi.uk.
+> Repo: `https://git.gosambi.uk/onie/portfolio` (single remote Gitea)
+> Lokal: `D:\HomeLabs\portfolio`
+> Terakhir diupdate: 2026-10-18
+
+## 1. Gambaran Umum
+
+Website statis (HTML tunggal) yang diserve via container `portfolio` (nginx:alpine).
+Akses publik: `https://gosambi.uk` dan `https://www.gosambi.uk` → `http://localhost:8091`.
+
+## 2. Deploy & Auto-Deploy
+
+- Container: `portfolio` (nginx:alpine)
+- File serve: `/DATA/AppData/portfolio/index.html` (di server)
+- Compose: `/var/lib/casaos/apps/portfolio-docker-compose.yml`
+- Sumber edit: `D:\HomeLabs\portfolio\index.html`
+- Tunnel: `gosambi.uk` + `www.gosambi.uk` → `http://localhost:8091` (backup `config.yml.bak-portfolio`)
+
+### Auto-deploy via Gitea Actions (2026-10-17)
+- Source of truth: `https://git.gosambi.uk/onie/portfolio.git`
+- Workflow: `.gitea/workflows/deploy.yml` — push ke `main` → runner SSH ke server → git pull `/home/gosa/portfolio` → copy `index.html` ke `/DATA/AppData/portfolio/`
+- Secrets repo: DEPLOY_PRIVATE_KEY (ed25519 `scripts/deploy_key`), DEPLOY_HOST=192.168.5.190, DEPLOY_USER=gosa
+- Pubkey deploy di `/home/gosa/.ssh/authorized_keys`
+- Akun Gitea: `onie` / token API `d36ff8...d91e` (scope read:repository)
+
+## 3. Catatan Infra Gitea (lihat juga rule.md)
+
+- Runner (act_runner, container `gitea-runner`): sempat rusak karena `GITEA_INSTANCE_URL` menunjuk IP Tailscale lama → FIX ke `http://127.0.0.1:3033` + edit file `.runner` di volume.
+- ROOT_URL: `https://git.gosambi.uk/` (fix 2026-10-18, sebelumnya IP Tailscale lama).
+- Debug runner: `docker logs gitea-runner`
