# Demo Deployment

This project can run behind the existing Caddy edge service with this temporary route:

```text
Caddy -> chatroom-nginx -> chatroom-app
```

The chatroom compose stack joins the existing external Docker network named `caddy_proxy`. No app ports are published to the host.

## Start the Chatroom Stack

From this project directory:

```powershell
docker compose up -d --build
docker compose ps
```

Test the FastAPI health endpoint through the Nginx container:

```powershell
docker compose exec chatroom-nginx wget -qO- http://chatroom-app:8000/health
```

## Temporary Caddy Change

Do this manually in:

```text
D:\Programing\Scripts\Home Lab\Interanet\caddy-deployment\config\caddy\Caddyfile
```

Add this temporary block:

```caddy
chat.amiirkhl.ir {
    import {$CADDY_TLS_MODE:custom_tls}
    reverse_proxy chatroom-nginx:80
}
```

If the current custom certificate does not include `chat.amiirkhl.ir`, use this instead:

```caddy
chat.amiirkhl.ir {
    import letsencrypt_tls
    reverse_proxy chatroom-nginx:80
}
```

Reload Caddy from the Caddy deployment directory:

```powershell
docker compose exec caddy caddy reload --config /etc/caddy/Caddyfile
```

## Browser Test

Open:

```text
https://chat.amiirkhl.ir
```

Use two browser tabs, join the same room, and send messages both ways. The frontend builds its WebSocket URL from the current page, so HTTPS should connect with:

```text
wss://chat.amiirkhl.ir/ws/{room}/{user}
```

## Undo After the Demo

1. Remove the `chat.amiirkhl.ir` block from the Caddyfile.
2. Reload Caddy:

```powershell
docker compose exec caddy caddy reload --config /etc/caddy/Caddyfile
```

3. Stop and remove the chatroom stack from this project directory:

```powershell
docker compose down
```
