Storage Provisioning Guide⚓︎

Introduction⚓︎

Persistent storage is essential for many applications deployed in Kubernetes. Kubernetes uses Storage Classes to provision persistent volumes dynamically. This guide provides general guidance on storage provisioning and how to ensure your cluster is ready to support applications that require persistent storage.

  • Storage Classes define how a unit of storage can be dynamically created.
  • Different storage classes map to different storage providers and types (e.g., local disks, network storage, cloud storage).
  • Each storage class has properties that define the provisioner, parameters, and reclaim policy.

If your cluster does not have a suitable storage class, you need to set one up. The method for doing this depends on your environment and the storage solution you wish to use.

Common Storage Solutions⚓︎

  • Cloud Provider Storage Classes: Most cloud providers offer managed storage solutions that integrate with Kubernetes (e.g., AWS EBS, Azure Disk, Google Persistent Disk).
  • Network File Systems (NFS): Allows multiple nodes to share the same storage.
  • Distributed Storage Systems: Solutions like Ceph, GlusterFS, or Longhorn also provide storage.
