# Storage in Kubernetes * Storage and stateful workloads are harder in all systems * Containers make it both harder and easier than before * StatefulSets is a new resource type, making Pods more sticky * Avoid stateful deployments for first few deployments until you're good at the basics * Use Database-as-a-Service whenever you can * Creating and connecting volumes: 2 types * Volumes * Tied to a lifecycle of a Pod * All containers in a single pod can share them * PersistentVolumes / PersistentVolumeClaims * Created at a cluster level, outlives a Pod * Separates a storage config from Pod using it * Multiple Pods can share them * CSI (Container Storage Interface) plugins are the new way to connect to storage --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
