>"Not directly, rook provides a storage backend for in-cluster workload persistent volumes." Right so is it fair to say that the use case for Rook is if you are running Kubernetes on bare metal? For instance if I'm Kubernetes cluster on AWS then AWS already provides PVC via EBS and S3 volumes. Or am I overlooking a use case where you would run Rook on cluster running on AWS/GCP? |

Rook runs a ceph cluster inside your kubernetes cluster to provide the storage. The downside is this consumes cpu/memory (and obviously storage) resources to run, whereas on AWS, EBS is integrated into the platform so it does not "run" inside your cluster (other than the aws cloud-provider that provides the integration).
If you wanted to run the same storage backend on bare metal and AWS, rook would enable that.
