enroot & pyxis - great recommendation for rootless containerized runtime 
environments in HPC.

Free software, no license or DGX required.


Some things to consider

Cache in /tmp so it's free'd upon reboot:
# /etc/enroot/enroot.conf
ENROOT_RUNTIME_PATH /tmp/enroot/user-$(id -u)
ENROOT_CACHE_PATH /tmp/enroot-cache/user-$(id -u)
ENROOT_DATA_PATH /tmp/enroot-data/user-$(id -u)


When using a local container repo, the image urls port is seperated 
using # :

> srun … --container-image mygitlab:5005#path/pytorch:22.12-py3 …
