From efe1176dd90ea38742c53c8588fbc83e6b9aefd6 Mon Sep 17 00:00:00 2001 From: Aditya R Date: Tue, 5 Jul 2022 12:06:47 +0530 Subject: specgen,run: support running container from valid manifest list Following PR adds support for running containers from a manifest list present on localstorage. Before this PR podman only supports running containers from valid images but not from manifest list. So `podman run -it --platform command` should become functional now and users should be able to resolve images on the bases of provided `--platform` string. Example ``` podman manifest create test podman build --platform linux/amd64,linux/arm64 --manifest test . podman run --rm --platform linux/arm64/v8 test uname -a ``` Closes: https://github.com/containers/podman/issues/14773 Signed-off-by: Aditya R --- pkg/specgen/generate/container.go | 11 ++++++++++- pkg/specgen/specgen.go | 6 ++++++ 2 files changed, 16 insertions(+), 1 deletion(-) (limited to 'pkg/specgen') diff --git a/pkg/specgen/generate/container.go b/pkg/specgen/generate/container.go index 30c759495..8fdd87adf 100644 --- a/pkg/specgen/generate/container.go +++ b/pkg/specgen/generate/container.go @@ -38,10 +38,19 @@ func getImageFromSpec(ctx context.Context, r *libpod.Runtime, s *specgen.SpecGen } // Need to look up image. - image, resolvedName, err := r.LibimageRuntime().LookupImage(s.Image, nil) + lookupOptions := &libimage.LookupImageOptions{ManifestList: true} + image, resolvedName, err := r.LibimageRuntime().LookupImage(s.Image, lookupOptions) if err != nil { return nil, "", nil, err } + manifestList, err := image.ToManifestList() + // only process if manifest list found otherwise expect it to be regular image + if err == nil { + image, err = manifestList.LookupInstance(ctx, s.ImageArch, s.ImageOS, s.ImageVariant) + if err != nil { + return nil, "", nil, err + } + } s.SetImage(image, resolvedName) inspectData, err := image.Inspect(ctx, nil) if err != nil { diff --git a/pkg/specgen/specgen.go b/pkg/specgen/specgen.go index 79e20667b..42b89ece1 100644 --- a/pkg/specgen/specgen.go +++ b/pkg/specgen/specgen.go @@ -103,6 +103,12 @@ type ContainerBasicConfig struct { // RawImageName is the user-specified and unprocessed input referring // to a local or a remote image.
