Kubernetes storage standards — choosing CSI drivers and access modes, StorageClass settings (reclaim policy, binding mode, expansion), Longhorn operations (replicas, data locality, backups, recurring jobs, upgrades), snapshots vs backups, and avoiding double replication for apps that replicate themselves. Use whenever creating or changing StorageClasses, PVCs for databases or monitoring, Longhorn configuration, volume backups, or when planning stateful workloads on Kubernetes.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Kubernetes storage standards <!-- devops-ai-kit · Last reviewed: 2026-10-28 --> ## Choose the storage type & access mode - **MUST** Databases (PostgreSQL, MySQL…): block storage with `ReadWriteOnce` or `ReadWriteOncePod`. Do not use NFS / RWX for a database engine. This includes Longhorn RWX, which runs through an NFS share-manager. - **SHOULD** Shared data (uploads, shared assets): prefer moving the app to object storage (S3 API). RWX through NFS CSI / CephFS / Longhorn RWX is **CONTEXT**, for when the app cannot be changed. - **SHOULD** Apps that replicate their own data (PostgreSQL with replicas, Loki / Prometheus HA, Kafka, Elasticsearch): think about fewer replicas at the storage layer. Avoid "replication on top of replication": 3 Longhorn copies × 3 app replicas = 9 copies of the data, 3 times the disk cost and the write latency. ## StorageClass - **MUST** Production uses `reclaimPolicy: Retain` for important data. The default `Delete` means deleting the PVC also deletes the data. - **SHOULD** `allowVolumeExpansion: true`. - **CONTEXT** `volumeBindingMode: WaitForFirstConsumer`: …

How to install
mdr add hoangminhung/devops-ai-kit/k8s-storage@sha256:a1d4447727fcf34eThe line at the top of this page pins the label git:20261028.645512f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
