Rook is a cloud native orchestrator for deploying storage systems within Kubernetes. This presentation will highlight the benefits and goes into the details of using Rook to set up a Ceph cluster. In addition, I will also show how to set up Prometheus and Grafana to monitor Ceph in this environment.

Deploying a Ceph Cluster
Installing Ceph
• RPM Packages
• All daemons on server have same version
External orchestrator
• Ansible, DeepSea, etc
Configure Ceph
• CLI, Dashboard
• Manage Pools, CephFS, RBD, etc
Day 2 operations
• Static deployment configuration

Kubernetes is Everywhere
• Industry standard
• The next big thing
• Extensible Kubernetes API
Why not run Ceph inside Kubernetes?
