The Rook toolbox is a container with common tools used for rook debugging and testing. The rook toolbox can run as a deployment in a Kubernetes cluster where you can connect and run arbitrary Ceph commands. Launch the rook-ceph-tools pod and enter inside
# The file is located in the folder "rook/cluster/examples/kubernetes/ceph"
$ kubectl create -f toolbox.yaml
# Once the rook-ceph-tools pod is running, you can connect to it with
$ kubectl -n rook-ceph exec -it deploy/rook-ceph-tools -- bash
Once inside the Pod you can check the status of the Ceph cluster with
# For the complete list of arguments use "ceph -h"
$ ceph status
