Four interactive, browser-based simulators — Spack, Apptainer, Slurm and Kubernetes. Real commands, real feedback, no setup required.
Start with KubernetesThe Four Trainers
Each trainer simulates a full Rocky Linux 9 environment in your browser. Type real commands, get real output — no VM, no Docker, no cloud account.

Open trainerBuild and run HPC containers. Learn SIF images, definition files, bind mounts, and GPU passthrough — the HPC-native container runtime.
Open trainerSubmit and manage HPC jobs. Practice sbatch, squeue, sacct, and job arrays on a simulated multi-node cluster — no allocation needed.
Open trainerLearn kubectl from first principles. Pods, deployments, services, namespaces and RBAC — CKA/CKAD prep without spinning up a cluster.
Open trainerThe Full Stack
Modern HPC and cloud-native deployments layer these four tools. Follow the path from package management to orchestration.
Build & install scientific software with precise version control and environment management.
Package Spack environments into portable, rootless SIF containers for reproducible execution.
Schedule containerised workloads across a multi-node cluster with queues, priorities and accounting.
Orchestrate services at scale — deployments, autoscaling, RBAC and cloud-native infrastructure.
