Automatic staging on a **self-hosted Gitea** machine: merge (or push) to **`master`** → build Docker images → push to Gitea Container Registry → deploy on the same host.
DNS `wixur.ir` must point at the **Windows** host. Production (`https://nudentic.ir` on Linux) is separate — see [`DEPLOY.md`](DEPLOY.md). Do **not** point `wixur.ir` at the Linux VPS.
Frontend public URLs are **baked in at build time** via `PUBLIC_BASE_URL`. After changing the public URL, re-run the Gitea workflow (or push to `master`) and set `FRONTEND_URL` in `C:\dyolink\secrets\backend.staging.env` to the same origin.

## Cut over from `:8088` to `http://wixur.ir`
DNS A record for `wixur.ir` → Windows IP (already done if `http://wixur.ir:3000` and `:8088` work).
On Windows: host nginx on **80** proxies to Docker **18088** ([`nginx/windows-edge-http.conf`](nginx/windows-edge-http.conf)). Remove portproxy on **80** (keep **8088** as fallback). Router must forward **80**. See §7.
**Why `host.docker.internal`?** Docker Desktop runs in a Linux VM. `docker login` runs from that VM — `127.0.0.1:3000` is the VM, not Gitea on Windows.
### 2b. Gitea `app.ini` — match registry URL
Edit `C:\gitea\custom\conf\app.ini`:
```ini
[server]
ROOT_URL = http://host.docker.internal:3000/
```
Restart Gitea. Gitea uses `ROOT_URL` for Docker registry auth redirects.
| **User profile → Settings → Actions → Runners** | Individual | Often **no** — jobs stay queued with “no matching online runner” |
If your runner shows **Type: Individual** in Gitea but jobs never start, delete it and re-register with an **instance** or **repository** token (table above).
**Verify:** open **your repo** → **Settings → Actions → Runners** — `windows-staging` must appear here as **Idle/Online** (not only under user settings).
| `REGISTRY_HOST` | `host.docker.internal:3000` | **Windows + Docker Desktop:** Docker runs in a Linux VM — `127.0.0.1` is the VM, not Gitea. Use `host.docker.internal:3000`. Gitea `ROOT_URL` should match this so registry login from CI works. Browsers can use `http://wixur.ir:3000` or `https://gitea.wixur.ir`. **Do not** set this to `gitea.wixur.ir` unless that HTTPS proxy allows unlimited body size (see 413 below). |
Gitea stays on **:3000**. Docker staging nginx binds **127.0.0.1:18088**. A **Windows nginx** (the 1.29.x you already have) listens on **80** and proxies to 18088. Config: [`nginx/windows-edge-http.conf`](nginx/windows-edge-http.conf).
**Mobinnet:** public **80** is the modem. Use **443** instead: router forward **TCP 443 → 192.168.1.100**, then `https://wixur.ir`. Let's Encrypt after mobile-data `/health` works (self-signed is enough for that test).
| `413 Request Entity Too Large` on `docker push` to `https://gitea.wixur.ir/v2/…/blobs/uploads` | Nginx (or Cloudflare) in front of Gitea is rejecting the image layer. **Fix the proxy** (then `nginx -s reload`): in the `server { server_name gitea.wixur.ir; }` block set `client_max_body_size 0;` and `proxy_request_buffering off;` — snippet: [`nginx/windows-gitea.wixur.snippet.conf`](nginx/windows-gitea.wixur.snippet.conf). **Or skip the proxy:** set `REGISTRY_HOST=host.docker.internal:3000` (and Gitea `ROOT_URL`) so CI pushes to `:3000`. If the hostname is orange-clouded on Cloudflare, grey-cloud it (free plan caps uploads at 100MB). |
| `TLS handshake timeout` to `registry-1.docker.io` / `node:20-alpine` | Docker Hub unreachable from the Windows runner. CI mirrors `node:20-alpine` into Gitea (`<REGISTRY_PREFIX>/node:20-alpine`) and builds from that. If Hub is down **and** the image is not on the machine: on the runner run `docker pull node:20-alpine` when Hub works, then re-run the workflow. Optional Docker Engine `registry-mirrors`. |
| `docker login` connection refused on `127.0.0.1:3000` | **Docker Desktop on Windows:** set `REGISTRY_HOST=host.docker.internal:3000`, add it to insecure-registries, set Gitea `ROOT_URL=http://host.docker.internal:3000/`. Keep `CLONE_HOST=127.0.0.1:3000` for git. |
| `docker login` / push denied, redirect to public IP | Set Gitea `ROOT_URL` to a host Docker can reach (`host.docker.internal:3000` on Windows Docker Desktop). |
| Port 80 bind forbidden / access permissions | Portproxy already owns 80. Bind Docker to `18088` and point portproxy **80 → 127.0.0.1:18088**. Free IIS if it holds 80. |
| `http://wixur.ir` unreachable / empty reply | Docker Desktop: run **portproxy** (§7). `127.0.0.1:18088/health` must work on Windows first. Router must forward **80**. |
