[🐛 Bug]: Can't connect to VNC when deployed on Azure Container

[Berets]

What happened?

Hi, i deployed a container based on the selenium/chrome_standalone. It works everything except the connection to VNC. Seems that the port it's not exposed, did i missed anything?

Thanks for the help

Do you want to see the VNC via noVNC Websocket? If yes, container port 7900 needs to be exposed to access from outside (http://:/?autoconnect=1&resize=scale&password=secret) If you want to access via protocol VNC, container port 5900 needs to be exposed to access from outside, then you can connect to VNC session via such client e.g VNCViewer

[Berets]

It's not this part of configuration that expose the port?

{ "protocol": "TCP", "port": 7900 }
