Rustdesk Docker on Raspberry Pi

I have install this docker-rustdesk but I cannot figure out the use case of this.

I try to access it but it just connects to a blank screen with just rustdesk gui client running.

I cannot figure out how is this useful ? Pardon me for my lack of understanding

Have you read the rustdesk documentation on their site?
Docs of RustDesk :: Documentation for RustDesk

I have read it not the whole thing as there are no search options in the docs.

I am running the docker in a headless environment. can you point to the right doc

I cannot, i do not use rustdesk. We provide support for the container, not the application within the container, which has its own support and documentation.

Do you believe you have a container issue?

Yeah it is the desktop program that is the whole point, it can be a server or client, but generally would be used as a client.
As to why, it is a mix of because we can and their native web version is not as feature complete as their desktop app.

The Rustdesk acts both as a server (it can be accessed from outside of the machine) and client (it can access other machines with rustdesk).

In rustdesk docker the rustdesk only acts as a client. it cannot be accessed from from other machines.

So I was just curious

Of course it can, you can connect from another client to control what is going on inside the container. Not super useful, but completely possible.
