Volume represents a named volume in a pod that may be accessed by any container in the pod.

Exposed Persistent volumes

  • persistentVolumeClaim (PersistentVolumeClaimVolumeSource)

    persistentVolumeClaimVolumeSource represents a reference to a PersistentVolumeClaim in the same namespace. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#persistentvolumeclaims

    PersistentVolumeClaimVolumeSource references the user’s PVC in the same namespace. This volume finds the bound PV and mounts that volume for the pod. A PersistentVolumeClaimVolumeSource is, essentially, a wrapper around another type of volume that is owned by someone else (the system).

    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.

The name of the PVC will be \<pod name>-\<volume name> where \<volume name> is the name from the PodSpec.Volumes array entry. Pod validation will reject the pod if the concatenated name is not valid for a PVC (for example, too long).

      An existing PVC with that name that is not owned by the pod will not be used for the pod to avoid using an unrelated volume by mistake. Starting the pod is then blocked until the unrelated PVC is removed. If such a pre-created PVC is meant to be used by the pod, the PVC has to updated with an owner reference to the pod once the pod exists. Normally this should not be necessary, but it may be useful when manually reconstructing a broken cluster.

  • image (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). The field spec.securityContext.fsGroupChangePolicy has no effect on this volume type.

    • image.pullPolicy (string)

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. Defaults to Always if :latest tag is specified, or IfNotPresent otherwise.

    • image.reference (string)

      Required: Image or artifact reference to be used. Behaves in the same way as pod.spec.containers[*].image.
