Install System Application

Install

Install the system app from DevBox. Due to the installation mechanism, the desktop may not receive proper notifications. Consequently, you might need to manually refresh the page to see the icon.

Once the application is successfully installed and in the 'Running' state, you can access the default welcome page of VSCode. Simply click the 'Open IDE' button on the 'Containers' page.

TIP

There is no need to bind in this case.

Clone Code

• Once you've entered the IDE, begin by installing the gh tool.

  apt install gh

• Log in to Github

  gh auth login

• Clone the code after logging in.

  cd /opt/code && gh repo clone beclab/desktop

  TIP

  It's recommended to clone the code into the /opt/code directory. This is because the code server is run by the root, while nginx is run by a non-root user. In this example, the /opt/code directory has been mounted to the application data directory of the node. So that, the code will remain saved even if the pod is restarted.

Run the Application

Run your application in the terminal of the IDE. For example:

npm run dev

Nginx

• Open the folder /opt/code/desktop-v1 in VS Code

• To run debugging, first modify the nginx configuration in the container.

  • Use VS Code to open the configuration file located at /etc/nginx/conf.d/default.conf.

• Modify the proxies for front-end and back-end testing.

  location / {
      proxy_pass http://127.0.0.1:9000;
      proxy_set_header            Host $http_host;
      proxy_set_header            X-real-ip $remote_addr;
      proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection $http_connection;
      proxy_set_header Accept-Encoding gzip;
  }
  
  location /api {
      proxy_pass http://127.0.0.1:3010;
      proxy_set_header            Host $http_host;
      proxy_set_header            X-real-ip $remote_addr;
      proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection $http_connection;
      proxy_set_header Accept-Encoding gzip;
  }

  You can also configure the proxy for other services in project, as an example.

  location /api/logout {
      add_header 'Access-Control-Allow-Headers' 'x-api-nonce,x-api-ts,x-api-ver,x-api-source';
      proxy_pass http://authelia-svc;
      proxy_set_header            Host $host;
      proxy_set_header            X-real-ip $remote_addr;
      proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
  
      add_header X-Frame-Options SAMEORIGIN;
  }

  The configuration is exactly the same as when running in Terminus OS, and no further modifications are required.

• Reload Nginx after modification.

nginx -s reload

• If you want to keep the default.conf of nginx, you can save it in either /root/.config or the code repository. Then, each time you restart the pod, go to VS Code Terminal and create a new soft link.

cd /etc/nginx/conf.d
rm default.conf
ln -s /root/.config/default.conf

nginx -s reload

After the nginx proxy is activated, you can initiate the front-end and back-end services in the VS Code Terminal.

WARNING

The service cannot be started on ports 80, 8080, and 3000.

Preview

After install the application, you can preview it by clicking on the app icon on the Terminus.
