How to configure multiple default Nucleus servers in Isaac Sim?

[rkdfuf2wkd]

I am using three computers (A, B, C), each with the following roles:

• A: Enterprise Nucleus Server (Nucleus Compose Stack 2023.2.9)

• B: Server running the Isaac Sim Streaming App (GPU: L40s)

• C: Server using the WebRTC Streaming Client (consuming the app running on B)

On computer B, when running the Isaac Sim container with Docker, I specify the nucleus server using the following options:

-e "OMNI_SERVER=omniverse://10.20.20.32" -e "OMNI_USER=admin" -e "OMNI_PASS=admin"

After starting the Streaming App on B, I can connect from C using the Streaming Client to the full Isaac Sim App. Then, through App → Content → Omniverse → Add New Connection, when I enter 10.20.20.32, the login happens automatically and the nucleus server is added successfully.

My question: If I want to add another Nucleus Server (i.e., use two Nucleus Servers), how should I do it?

You would just run the same command again and add a new Nucleus Connection. " App → Content → Omniverse → Add New Connection" You are not limited to one connection. You can have many.

When I try to connect to a server that wasn’t registered via environment variables (for example, -e "OMNI_SERVER=~~") using Add New Connection, the following message appears immediately:

Unable to connect server ‘omniverse://myserver’. Please check your internet connection then try again

I’m running Isaac Sim on the server in headless mode and connecting from another computer using the Isaac Sim WebRTC Streaming Client.

I think this error shows up because adding a Nucleus server attempts to open an external browser, and in my current setup an external browser can’t be launched.

@rkdfuf2wkd

-e "OMNI_SERVER=omniverse://10.20.20.32" -e "OMNI_USER=admin" -e "OMNI_PASS=admin"

Ah I see. So in that case, please add additional Nucleus Server connections directly to your container launch code, as you have already done here
