How to view docker image package sizes using docker scout on sbom or other

How to use docker scout to get sbom details from a docker image

• docker scout sbom --format list cgr.dev/chainguard/wolfi-base

output:

How can I see the image size in an extra column to the right?

• Is there maybe a bash pipe command I can use to create it myself (extracting the size from an external source)? or is there an additional command I can use in the docker scout to show it?

Also curious why: docker scout cves cgr.dev/chainguard/wolfi-base

shows total size as 7.2MB

BUT

• docker image inspect

shows. "Size": 15394739:

(ie 15.4mb)

Using docker image ls it also shows as 15.4mb so I assume thats the final image size, but not sure why docker scout cves shows it differently.

The size shown by docker scout cves is the compressed size stored by the registry (and transferred in docker pull). The 15.4 MB will be the uncompressed size on disk.

Regarding formatting, I think the best solution would be to write a program which reads the json output from docker scout and complements it with size data then writes out a new table.
