Image is skipped when running check

Hey, i have a weird problem. First here is the list of images that are on the system:

for some reason it is not checking the nextcloud:29 image.

If i check it "manually" with docker run --rm -v /var/run/docker.sock:/var/run/docker.sock ghcr.io/sergi0g/cup check nextcloud:29
I get this:

nextcloud:29 has an update available

Any ideas?

P.S. the link to the documentation is broken (https://sergi0g.github.io/cup/docs/introduction)

[brtwrst]

Well nevermind, I fixed it by deleting the nextcloud image and downloading it again. Now it's showing up in the check command.

[sergi0g]

That's unusual. I'm glad you solved it!

Fixed the broken link! 😉

[brtwrst]

Hey, so it has happened again, cup is currently not checking/reporting on my nextcloud:29 image. it is totally absent from the result like in the "screenshots" above.

I'm using the latest available cup image with version 2.1.0

$ docker run --rm -v /var/run/docker.sock:/var/run/docker.sock ghcr.io/sergi0g/cup --version
cup 2.1.0

I will leave it in this state for now and not delete and redownload the nextcloud image - maybe you want me to "run some tests" while it's in this broken state.

[sergi0g]

@brtwrst I'm sorry you're having this issue again. Can you please provide the output of docker inspect nextcloud:29?

Ah, I see the problem. The image is skipped due to this line: https://github.com/sergi0g/cup/blob/main/src%2Fdocker.rs#L37

Your Nextcloud image has 2 digests for some reason. I'll update the code when I can to handle this situation. Thanks for opening this issue!

[brtwrst]

Thanks for your time

[sergi0g]

Hi again! It looks like the fix I'll push won't break anything, however the only image that has 2 different digests on my system is alpine. No idea why.

[brtwrst]

Might have to do with multiplatform images https://stackoverflow.com/questions/69581269/docker-image-with-2-different-sha256-digests

[sergi0g]

I have a bunch of multiplatform images. Maybe I've pulled alpine for both amd64 and arm64?
