Nucleus server installation without launcher

Omniverse Isaac Sim
1

isaac sim already installed using container. Is there a way to install nucleus server without launcher in the headless server?
I follow the instruction in the doc below,

$ mkdir -p ~/.nvidia-omniverse/config
$ mkdir -p ~/.config/autostart
$ sudo apt install unzip -y
$ unzip <nucleus_installer.zip> -d nucleus_installer
$ cd nucleus_installer
$ setup/nucleus-setup -i # To install
$ setup/nucleus-setup -u # To uninstall

The service is running checked by systemctl, but it seems not working and no way login (can not visit ip:3080 or ip:8080). And sim container is still checking nucleus server. Is there anything missing?

I’m afraid there is a limitation using the headless installer. The Nucleus server can only be access locally.

Did you try running the installer on the server natively and not in the container? When using --network=host when running the container, it should be able to access the local server.

I am using isaac sim in the container and install the nucleus with nucleus_installer.zip out of container. The isaac sim container is running with – network=host. But it seems not working at all?
BTW, both are installed in the headless machine with no ubuntu gui, which I can not use launcher to install nucleus.

Hi @charmyoung

I run Isaac Sim in similar conditions.
I have a container for Isaac Sim and a container for Nucleus, both headless in a remote workstation…

I am exposing nucleus services to any external Isaac Sim instance by using the redir tool.
This is the bash script I am launching inside the container running nucleus.
Also, I can access to the web service by using http://172.17.8.207:8080/omniverse://172.17.8.207/

Where, 172.17.8.207 is the remote workstation IP. Change it to your IP

Hope this help in some way :)
