KEP of the Week
KEP 4639: Add OCI VolumeSource CRI API
The OCI has added a spec for "artifacts" being distributed as container images. With this KEP, Kubernetes will be taking advantage of the new capabilities as a way of distributing shared files to pods. It adds a new VolumeSource type of OCIObject, which can then get pulled down and mounted as a filesystem just like other volumes. This can be used for secrets, large data blobs, and shared configuration file sets.
An API was merged last week, and a full alpha release is planned for 1.31.
