We have released our code of a new container runtime interface (CRI) to submit batch jobs to HPC clusters. It is a modulable CRI for kubernetes which manages the pod lifecycle and allows to configure adapters for different container runtimes or resource managers such as SLURM. In addition, it provides multi-CRI for kubernetes, so different CRIs can be configured by setting the RuntimeClass pod attribute.
You can find the code here: https://github.com/atrioinc/multi-cri
We would like to have your feedback, thanks
