include arch/os in image libpod list

[benoitf]

Feature request description

Today,

 "Architecture": "arm64",
"Os": "linux",

are only available when we inspect an image

But usually this information is useful when we want to list images. For example to know if an image is using amd64 or Apple Silicon computer, etc.

so it requires one additional query for each image.

Suggest potential solution

Include

 "Architecture": "arm64",
"Os": "linux",

as part of libpod/images/json return this information

could be with an additional query parameter to the endpoint ?arch=true&os=true, ?displayArchAndOs, whatever so opt-in query.

Have you considered any alternatives?

@vrothberg PTAL, I think the problem here is that libimage does not return these by default but only in inspectinfo. Valentin would their be a penalty to return these automatically in list?

libimage returns libimage.Image objects that can be queried for this information.

Yes, this information comes at some cost. In theory, Podman Desktop could get this information in two steps:

1. List all images.
2. Inspect each image for the OS/Arch information.

It could certainly be made part of images/json; maybe via an opt-in parameter.

PS: I have no time to implement this feature at the moment.
