Does cwl runner have kubernetes support? Or is there someone developing it?

Thank you.

Hi @xiao2,

From the list of CWL runners/implementations

You could try REANA. Apache-Airflow supports Kubernetes, so perhaps CWl-Airflow would also work.

Although it's not yet reflected on CWL's runner list, Toil has support for running on Kubernetes, and it can run CWL workflows. Although there's no combined example, toil-cwl-runner will accept --batchSystem kubernetes.

There's also Calrissian, which looks to be an option if your Kubernetes cluster has ReadWriteMany PersistentVolumes.

Hello @xiao2, there is a Kubernetes helm chart being developed for Arvados at https://github.com/arvados/arvados-k8s, though I have not personally used it.
