I posted a question about Buildah storage on an internal Red Hat list. It was suggested that people on the atomic-devel list might be interested in the answer and possibly further discussion. Here it is.

You can commit an image directly to any location that "buildah push" can push an image to, and by virtue of buildah using the containers/image library for reading (pulling) and writing (pushing) images, we've got a decent amount of flexibility. There should be a list of examples in the buildah-push(1) man page. FWIW, the containers-storage location that buildah uses by default is the same place that cri-o uses for storing local copies of images, so images pulled from a registry by either cri-o or buildah, or committed by buildah, should be visible to both. > 2.

Skopeo can, as well as anything that uses the containers/image library for moving images around, such as podman, but I don't have an exhaustive list. buildah-push: https://github.com/projectatomic/buildah/blob/master/docs/buildah-push.md skopeo: https://github.com/projectatomic/skopeo/blob/master/docs/skopeo.1.md podman: https://github.com/projectatomic/libpod/blob/master/docs/podman-pull.1.md https://github.com/projectatomic/libpod/blob/master/docs/podman-push.1.md HTH, Nalin ------------- Chris Negus Red Hat Principal Technical Writer RHCA, RHCI, RHCX, RHCE Author of the Linux Bible, 9th Edition http://amzn.to/1IBA7NF
