Persistent Storage with Kubernetes in Production - Which Solution and Why?
summary
Compares storage options for Kubernetes with concrete rules and examples: presents eight principles for cloud‑native storage, explains Kubernetes PV/PVC and StorageClass dynamic provisioning, and flags CSI (alpha in 1.9) as the vendor plugin path. Recommends object stores (S3/Glacier) for backups, shared filesystems or object storage for uploads, and block volumes for databases; warns against plain NFS for on‑prem. Shows StorageOS demo (daemonset, one‑node demo) that creates a cluster pool and uses full‑volume synchronous replication to two replicas; notes EBS attach/detach 45s–1hr problem.
