I'm implementing a multi-user container infrastructure for Scientific Computing at nersc.gov called 'Spin'. Our first generation is based on Rancher 1.6 and is used to host a wide variety of non-HPC Scientific Computing projects. HPC projects at NERSC mostly use our Shifter software.

Our next generation will be based on Rancher 2 and will use Kubernetes under the hood. We're looking at using Rancher Projects with Namespaces, OPA + other controls to enforce user containers to run as their own Linux UserID so they can access resources using normal Linux access control.
