Now open a browser and navigate to your dev VM on port 6901.
Running noVNC from source
-------------------------
If you need to debug or make changes to the UI code, use the following procedures to use npm to serve the web code. The code will automatically rebuild when changes are made and the code will not be packaged.
These steps assume you have already built the docker image covered in the previous section named `kasmvnc:dev`.
```bash
# run an instance of the dev container, expose an additional port
sudo docker run -it -v ./:/src -p 6901:6901 -p 8443:8443 --name kasmvnc_dev kasmvnc:dev
```
Now from inside the container. **This assumes KasmVNC is already built, follow steps above if you need to build KasmVNC**
```bash
# Run KasmVNC
/src/xorg.build/bin/Xvnc -interface 0.0.0.0 -PublicIP 127.0.0.1 -disableBasicAuth -RectThreads 0 -Log *:stdout:100 -httpd /src/kasmweb/dist -sslOnly 0 -SecurityTypes None -websocketPort 6901 :1 &
/usr/bin/xfce4-session --display :1 &
sudo nginx
cd kasmweb
npm install
npm run serve # <-- Needs to run in foreground
```
Now open a browser and navigate to your dev VM on port 8443 over https.
NGINX is proxying the websocket to KasmVNC and all other requests go to the node server. NGINX listens on 8443 with ssl.
Since `npm run serve` needs to run in the foreground, you may need to exec into the container from another terminal to run additional commands like stopping Xvnc, rebuilding KasmVNC, etc.
```bash
sudo docker exec -it kasmvnc_dev /bin/bash
```
