Podman is an Open Containers Initiative (OCI)‑compliant, daemonless and rootless container tool developed by Red Hat. Unlike Docker, Podman operates without a central daemon and supports secure rootless execution, making it well‑suited for HPC environments and schedulers such as Slurm.
Podman is available on all OSC clusters. Only one version is available at any given time. To find out the current version:

Apptainer (formerly Singularity) is a container system designed for use on High Performance Computing (HPC) systems. It allows users to run both Docker and Singularity containers.
It is now possible to run Docker and Apptainer/Singularity containers on all clusters at OSC. Single-node jobs are currently supported, including GPU jobs; MPI jobs are planned for the future.
From the Docker website: "A container image is a lightweight, stand-alone, executable package of a piece of software that includes everything needed to run it: code, runtime, system tools, system libraries, settings."
