The presentation is about the installation and expansion of Rook, a cloud-native storage orchestrator, using Kubernetes.
- Rook is a cloud-native storage orchestrator that automates storage management in cloud-native environments.
- Rook can be installed in two ways: host-based cluster and PVC-based cluster.
- PVC-based cluster is suitable for simple clusters and is easy to expand by increasing the count field.
- Advanced configurations of PVC-based cluster include creating OSDs on demand and even OSD splitting among all nodes.
- The presentation includes a demo of creating a simple Rook PVC-based cluster with one node and expanding it to two OSDs.
The presenter demonstrated how easy it is to expand a Rook PVC-based cluster by simply increasing the count field from 1 to 2. The process involved creating a manager port, initializing data structure on top of the local block device, and creating the second OSD data structure. The presenter also mentioned advanced configurations of PVC-based cluster, such as creating OSDs on demand and even OSD splitting among all nodes.
