### Start Fluxer Stack with Docker Compose

Source: https://github.com/fluxerapp/fluxer/blob/main/fluxer_docs/docs/operator/get-started.md

Use this command to start the Fluxer services in detached mode. For Cloudflare Tunnel configurations, use the combined compose files.

```bash
docker compose up -d
```

```bash
docker compose -f docker-compose.yml -f cloudflared.compose.yml up -d
```

### JavaScript Initialization for WebAssembly Threading

Source: https://github.com/fluxerapp/fluxer/blob/main/fluxer_desktop/native/webrtc-sender/vendor/tract-linalg-0.23.1/MULTITHREAD_BENCHMARKS.md

Initialize the WebAssembly module and thread pool in JavaScript. This setup is crucial for wasm-bindgen-rayon to function correctly with multiple threads.

```javascript
import init, { initThreadPool, df_set_thread_count } from './pkg/df.js';
await init();
await initThreadPool(navigator.hardwareConcurrency);  // wasm-bindgen-rayon
df_set_thread_count(4);  // sets Executor::RayonGlobal in tract-linalg
```

--------------------------------

### Download Fluxer Stack Files

Source: https://github.com/fluxerapp/fluxer/blob/main/fluxer_docs/docs/operator/get-started.md

Create a directory and download the core configuration files for Fluxer self-hosting.

```bash
mkdir fluxer
cd fluxer

base=https://raw.githubusercontent.com/fluxerapp/fluxer/main/deploy/self-hosting
curl -fsSLO "$base/docker-compose.yml"
curl -fsSLO "$base/Caddyfile"
curl -fsSLO "$base/livekit.yaml"
curl -fsSL "$base/.env.example" -o .env
```

--------------------------------

### Monitor Fluxer Stack Startup

Source: https://github.com/fluxerapp/fluxer/blob/main/fluxer_docs/docs/operator/get-started.md

Check the status of running services and view logs for the API service during startup. Initial startup may take several minutes.

```bash
docker compose ps
```

```bash
docker compose logs -f api
```

--------------------------------

### Verify Fluxer Web App and Assets

Source: https://github.com/fluxerapp/fluxer/blob/main/fluxer_docs/docs/operator/get-started.md

Check the HTTP headers for the main web app, admin login page, and static assets. This helps confirm that the services are running and accessible.

```bash
curl -fsSI "https://$FLUXER_DOMAIN" | sed -n '1,8p'
curl -fsSI "https://$FLUXER_DOMAIN/admin/login" | sed -n '1,8p'

asset=$(curl -fsS "https://$FLUXER_DOMAIN" | grep -o 'src="[^"]*/assets/[^" ]*"' | head -n1 | cut -d'"' -f2)
case "$asset" in
  http*) curl -fsSI "$asset" | sed -n '1,8p' ;; 
  /*) curl -fsSI "https://$FLUXER_DOMAIN$asset" | sed -n '1,8p' ;; 
esac

curl -fsSI "https://$FLUXER_DOMAIN/fonts/ibm-plex.css?v=3" | sed -n '1,8p'
curl -fsSI "https://$FLUXER_DOMAIN/web/favicon-32x32.png" | sed -n '1,8p'
```

--------------------------------

### Verify Docker and Compose Versions

Source: https://github.com/fluxerapp/fluxer/blob/main/fluxer_docs/docs/operator/get-started.md

Check if Docker Engine and the Compose plugin meet the minimum version requirements.

```bash
docker --version
docker compose version
```

--------------------------------

### Configure Custom WebRTC Path

Source: https://github.com/fluxerapp/fluxer/blob/main/fluxer_desktop/native/webrtc-sender/vendor/webrtc-sys/libwebrtc/README.md

Specifies the path to a custom WebRTC build within the LiveKit configuration file. This allows the SDK to use a pre-built or custom-compiled WebRTC library.

```toml
[env]
LK_CUSTOM_WEBRTC = { value = "webrtc-sys/libwebrtc/linux-x64-release", relative = true }

```

--------------------------------

### Build tract-linalg with Relaxed SIMD

Source: https://github.com/fluxerapp/fluxer/blob/main/fluxer_desktop/native/webrtc-sender/vendor/tract-linalg-0.23.1/WASM_RELAXED_SIMD.md

Builds the tract-linalg crate with both `simd128` and `relaxed-simd` features, offering a performance boost on FMA-capable hosts.

```sh
RUSTFLAGS='-C target-feature=+simd128,+relaxed-simd' \
  cargo build --release --target wasm32-wasip1 -p tract-linalg
```

--------------------------------

### Verify Fluxer Instance Discovery

Source: https://github.com/fluxerapp/fluxer/blob/main/fluxer_docs/docs/operator/get-started.md

Check instance discovery by querying the well-known Fluxer endpoint. This verifies self-hosted status and the availability of key service endpoints.

```bash
curl -fsS "https://$FLUXER_DOMAIN/api/.well-known/fluxer" | jq '.features.self_hosted, .endpoints.admin, .endpoints.gateway, .endpoints.media, .endpoints.static_cdn'
```

--------------------------------

### Build Linux WebRTC

Source: https://github.com/fluxerapp/fluxer/blob/main/fluxer_desktop/native/webrtc-sender/vendor/webrtc-sys/libwebrtc/README.md

Builds the WebRTC native library for Linux with specified architecture and profile. After execution, the artifact will be available in a platform-specific directory.

```sh
./build-linux.sh --arch x64 --profile release

```
