Setting up a Ceph cluster with Rook on a Raspberry Pi k3s cluster
Introduction Due to the low IOPS of the micro SD cards, I decided to switch to external NVMe SSDs. In addition to the boot partition, each SSD has a large unused partition that I am utilizing to provision Kubernetes Persistent Volumes through a Rook Ceph Cluster. I chose this approach as a learning opportunity to explore Kubernetes-native storage. Since my cluster isn’t running any critical applications, I don’t need data replication, so Local Persistent Volumes would have been sufficient. However, in production environments, the following requirements often arise:
