Redis not listed in the artifact lists of the bitnami/redis image

[dwertent]

What happened:
I am creating an SBOM for the docker.io/bitnami/redis image.
As I was looking at the artifacts, I noticed that the redis binary was absent from the list of artifacts in the SBOM.
bitnami/redis SBOM syft-1.1.1

What you expected to happen:
The redis binary should be listed as an artifact in the SBOM

Steps to reproduce the issue:

syft docker.io/bitnami/redis@sha256:c1843bcdb2f413d2aff67adbaf482082673cd40ec602fa9fefad74ec685cb813 --output syft-json=syft-redis-sbom.json

Anything else we need to know?:

I compared the SBOM with syft version 0.101.1 and the only difference is that in the older version there is a mention of the redis in the list of artifacts:

bitnami/redis SBOM syft-0.101.1

Environment:

• Output of syft version:

Application: syft
Version:    1.1.1
BuildDate:  2024-04-04T14:34:19Z
GitCommit:  Homebrew
GitDescription: [not provided]

GoVersion:  go1.22.2
Compiler:   gc

• OS (e.g: cat /etc/os-release or similar): macos, m1

I think this is because the binary classifier for redis matches against the amd64 build of redis but _not_the arm64 build.

❯ syft -q --platform=linux/amd64 docker.io/bitnami/redis@sha256:c1843bcdb2f413d2aff67adbaf482082673cd40ec602fa9fefad74ec685cb813 | grep -i ^redis
redis                             7.2.4                  binary
❯ syft -q --platform=linux/arm64 docker.io/bitnami/redis@sha256:c1843bcdb2f413d2aff67adbaf482082673cd40ec602fa9fefad74ec685cb813 | grep -i ^redis

I believe the digest points to a multi-architecture manifest, so when syft asks docker to pull the image, the client decides which platform to pull, and if the client pulls the linux/amd64 platform, redis is found, but not if it pulls the linux/arm64 platform.

I'll leave this issue open as a request to enhance the binary classifier to detect the arm64 build of redis.

Please let me report additional not listed cases.

syft does not detect redis frmo 3/8 OS/ARCH of redis:latest.

$ syft -q --platform=linux/386 redis | grep redis
$

$ syft -q --platform=linux/arm/v5 redis | grep redis
$

$ syft -q --platform=linux/arm/v7 redis | grep redis
$
