How to use render streaming on a server with no display but only a graphic card

I want to use render streaming in docker container on the server which only has a Nvidia GPU without display monitor. But there are few tutorial on how to achieve this function. Could someone teach me how to do?

### Package version 3.1.0-exp.4 ### Environment ```markdown * OS: Ubuntu 20.0…4 Desktop * Unity version: 2021.3.10f1c1 * Graphics API: Vulkan * Browser: Chrome ``` ### Steps To Reproduce Build any of the example scene into a linux package, e.g. the WebBrowserInput scene, **with only Vulkan API checked** in Player Setting ### Current Behavior The built program could be started with `./Program.x86_64` in bash, everything is fine. But when I added a batchmode tag like `./Program.x86_64 -batchmode`, the program crashed with error log: ``` Vulkan API version 1.1.0 (1.3.205 supported by driver, 1.1.0 requested) Vulkan vendor=[NVIDIA] id=[10de] Vulkan renderer=[NVIDIA GeForce GTX 1060 6GB] id=[1c03] Vulkan device type 2 Vulkan driverversion=[0x80d30000] uint=[-2133655552] Vulkan PSO: Cache data successfully loaded [size=187390,path=/tmp/DefaultCompany/HelloUnity1/vulkan_pso_cache.bin] Begin MonoManager ReloadAssembly - Completed reload, in 0.092 seconds UnloadTime: 0.669927 ms Signaling: Connecting WS ws://localhost Signaling: WS connected.

The reason I want to add `-batchmode` is because I want to start the program on a remote headless linux server.
