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
