Native Kubernetes Storage on CloudStack: Inside the CSI Driver
Apache CloudStack has quietly become a serious Kubernetes host via CKS (CloudStack Kubernetes Service) and CAPC (Cluster API Provider CloudStack). But a Kubernetes cluster without persistent storage is a stateless toy: databases, message queues, and anything that needs to survive a pod restart need real, attachable, resizable disks. That’s the gap the cloudstack-csi-driver closes. It […]
Console Access for Orchestrator Extensions in Apache CloudStack
Apache CloudStack continues to evolve its Extensions Framework to better support diverse virtualization platforms and external orchestrators.
