An image volume source represents an OCI object (a container image or artifact) which is available on the kubelet's host machine. An example of using the image volume source is The volume is resolved at Pod startup, depending on which pullPolicy value is provided Always : The kubelet always attempts to pull the reference. If the pull fails, the kubelet sets the Pod to Failed. Never : The kubelet never pulls the reference and only uses a local image or artifact. The Pod becomes Failed if any layers of the image aren't already present locally, or if the manifest for that image isn't already cached. IfNotPresent : The kubelet pulls if the reference isn't already present on disk. The Pod becomes Failed 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. At a minimum, they must include all valid types supported by the container image field. The OCI object gets mounted in a single directory (spec.containers[].volumeMounts[].mountPath) and will be mounted read-only. subPath or subPathExpr mounts for containers (spec.containers[].volumeMounts[].subPath, spec.containers[].volumeMounts[].subPathExpr) are only supported from Kubernetes v1.33. The field spec.securityContext.fsGroupChangePolicy has no effect on this volume type. The AlwaysPullImages Admission Controller does also work for this volume source like for container images. The following fields are available for the image type … Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
