Rook Toolbox

The Rook toolbox is a container with common tools used for rook debugging and testing. The toolbox is based on CentOS, so more tools of your choosing can be easily installed with yum.

The toolbox can be run in two modes:

1. Interactive: Start a toolbox pod where you can connect and execute Ceph commands from a shell
2. One-time job: Run a script with Ceph commands and collect the results from the job log

Prerequisite: Before running the toolbox you should have a running Rook cluster deployed (see the Quickstart Guide).

Interactive Toolbox

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:

kubectl create -f deploy/examples/toolbox.yaml

Wait for the toolbox pod to download its container and get to the running state:

kubectl -n rook-ceph rollout status deploy/rook-ceph-tools

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

All available tools in the toolbox are ready for your troubleshooting needs.

Example:

• ceph status
• ceph osd status
• ceph df
• rados df

When you are done with the toolbox, you can remove the deployment:

kubectl -n rook-ceph delete deploy/rook-ceph-tools

Toolbox Job

If you want to run Ceph commands as a one-time operation and collect the results later from the logs, you can run a script as a Kubernetes Job. The toolbox job will run a script that is embedded in the job spec. The script has the full flexibility of a bash script.

In this example, the ceph status command is executed when the job is created. Create the toolbox job:

kubectl create -f deploy/examples/toolbox-job.yaml

After the job completes, see the results of the script:

kubectl -n rook-ceph logs -l job-name=rook-ceph-toolbox-job
