Modern HPC schedulers like Slurm are able to run containerized workloads making the problem of portability less painful. For batch workload K8s is not sufficient. You need a workflow engine on top like Kubeflow or Airflow, so run you jobs. Thus. consider K8s more as a cluster operating software, but not as a fully-enabled workload management like slurm. Furthermore, K8s has so many features you do not need in HPC environments, where high throughput and load occupation is paramount.
