Rook Host Cluster

Rook Host Cluster deploys a Ceph host storage cluster using Rook CRs as defined by Rook Operator.

The reference architecture implemented by this module is one with a dedicated node pool with directly attached storage provisioned by a human operator, as summarised in the following diagram: Fury Storage Reference Architecture

⚠️ WARNING Most probably, you don't want to use this package as-is but you want to choose in which nodes the Ceph cluster will be deployed. Head over to the example that shows how to do that.

Requirements

Image repository and tag

  • Ceph image: registry.sighup.io/fury/ceph/ceph:v17.2.

Configuration

This package deploys Ceph with the following configuration:

  • 2 MGRs
  • 3 MONs and OSDs
  • RBD pool with replication enabled
  • CephFS filesystem with replication enabled and hot standby on metadata pool

Deployment

You can deploy Rook Host Cluster by running the following command:

kustomize build | kubectl apply -f -

Accessing Ceph dashboard

You can access the Ceph dashboard with your browser by port-forwarding on port 8443:

kubectl port-forward svc/rook-ceph-mgr-dashboard 8443:8443 --namespace rook-ceph

You can retrieve the generated credentials for the admin user running the following command:

kubectl -n rook-ceph get secret rook-ceph-dashboard-password -o jsonpath="{['data']['password']}" | base64 --decode && echo

Now if you go to https://127.0.0.1:8443 on your browser you can authenticate and interact with your Ceph cluster.

⚠️ WARNING Be careful since, by default, the dashboard gives you R/W access to your Ceph cluster and you risk of deleting resources created throught the operator CRDs.
