As usual we start out by taking a peak at the docs:


in order to install this the servers will need lvm2 installed, if you used the ansible playbook from the previous post then you ll already have this package on the k3s servers.

apt install -y lvm2

install the operator

kubectl apply -f crs.yaml common.yaml operator.yaml

we now wait for the operator pod to become available

kubectl get pods -n rook-ceph

###install the cluster

kubectl apply -f cluster.yaml

watch pods & wait for them to come online:

kubectl -n rook-ceph get pod

access the dashboard

next thing we wanna do is access the build in ceph dashboard which provides great info about the storage/usage you can do so by exporting the password from the secret store and then creating a tunnel to the service

kubectl -n rook-ceph get secret rook-ceph-dashboard-password -o jsonpath="{['data']['password']}" | base64 --decode && echo
kubectl -n rook-ceph port-forward service/rook-ceph-mgr-dashboard 8443:8443



note: if you experiment with rook/ceph make sure to clean your devices and the /var/lib/rook folders for leftovers from the previous test, else you might ruin a beautiful sunday by learning how to debug ceph - which in itself is not bad either ;)
