csi: Option<CSIVolumeSource>

csi (Container Storage Interface) represents ephemeral storage that is handled by certain external CSI drivers. +optional

ephemeral: Option<EphemeralVolumeSource>

ephemeral represents a volume that is handled by a cluster storage driver. The volume’s lifecycle is tied to the pod that defines it - it will be created before the pod starts, and deleted when the pod is removed.

Use this if: a) the volume is only needed while the pod runs, b) features of normal volumes like restoring from snapshot or capacity tracking are needed, c) the storage driver is specified through a storage class, and d) the storage driver supports dynamic volume provisioning through a PersistentVolumeClaim (see EphemeralVolumeSource for more information on the connection between this volume type and PersistentVolumeClaim).

Use PersistentVolumeClaim or one of the vendor-specific APIs for volumes that persist for longer than the lifecycle of an individual pod.

Use CSI for light-weight local ephemeral volumes if the CSI driver is meant to be used that way - see the documentation of the driver for more information.

A pod can use both types of ephemeral volumes and persistent volumes at the same time.

+optional

image: Option<ImageVolumeSource>

image represents an OCI object (a container image or artifact) pulled and mounted on the kubelet’s host machine. The volume is resolved at pod startup depending on which PullPolicy value is provided:

• Always: the kubelet always attempts to pull the reference. Container creation will fail If the pull fails.
• Never: the kubelet never pulls the reference and only uses a local image or artifact. Container creation will fail if the reference isn’t present.
• IfNotPresent: the kubelet pulls if the reference isn’t already present on disk. Container creation will fail if the reference isn’t present and the pull fails.

The volume gets re-resolved if the pod gets deleted and recreated, which means that new remote content will become available on pod recreation. A failure to resolve or pull the image during pod startup will block containers from starting and may add significant latency. Failures will be retried using normal volume backoff and will be reported on the pod reason and message. The types of objects that may be mounted by this volume are defined by the container runtime implementation on a host machine and at minimum must include all valid types supported by the container image field. The OCI object gets mounted in a single directory (spec.containers[].volumeMounts.mountPath) by merging the manifest layers in the same way as for container images. The volume will be mounted read-only (ro) and non-executable files (noexec). Sub path mounts for containers are not supported (spec.containers[].volumeMounts.subpath) before 1.33. The field spec.securityContext.fsGroupChangePolicy has no effect on this volume type. +featureGate=ImageVolume +optional
