Notes from building and operating open-source cloud infrastructure.
A Ceph storage fabric with dual-leaf redundancy
Three monitor hosts and three OSD hosts, each with two dual-port NICs, dual-homed to a pair of leaf switches.
cat ceph-storage-fabric.md →Operating OpenStack without fear
A calm upgrade starts with a map of the control plane, a tested rollback, and a clear definition of done.
cat operating-openstack-without-fear.md →Ceph’s data path is simpler than its operations
Object clients talk to RGW, RGW talks to the monitor quorum, and the OSDs do the actual work. The operational complexity lives around that path.
cat cephs-data-path.md →The Kubernetes control plane, as it actually runs on OpenStack
A request-path view of Kubernetes on OpenStack: ingress, apiserver, etcd, kubelet, Ceph CSI, and the failure modes between them.
