We added the concept of image volumes in 2.2.0, to support inspecting an image from within a container. However, this is a strictly read-only mount, with no modification allowed. By contrast, the new `image` volume driver creates a c/storage container as its underlying storage, so we have a read/write layer. This, in and of itself, is not especially interesting, but what it will enable in the future is. If we add a new command to allow these image volumes to be committed, we can now distribute volumes - and changes to them - via a standard OCI image registry (which is rather new and quite exciting). Future work in this area: - Add support for `podman volume push` (commit volume changes and push resulting image to OCI registry). - Add support for `podman volume pull` (currently, we require that the image a volume is created from be already pulled; it would be simpler if we had a dedicated command that did the pull and made a volume from it) - Add support for scratch images (make an empty image on demand to use as the base of the volume) - Add UOR support to `podman volume push` and `podman volume pull` to enable both with non-image volume drivers Signed-off-by: Matthew Heon <matthew.heon@pm.me> |
