From 7fea46752cbfb0ef7bfdd694afe95038c9875212 Mon Sep 17 00:00:00 2001 From: Valentin Rothberg Date: Fri, 31 Jul 2020 09:27:21 +0200 Subject: support multi-image (docker) archives Support loading and saving tarballs with more than one image. Add a new `/libpod/images/export` endpoint to the rest API to allow for exporting/saving multiple images into an archive. Note that a non-release version of containers/image is vendored. A release version must be vendored before cutting a new Podman release. We force the containers/image version via a replace in the go.mod file; this way go won't try to match the versions.
