Use 'docker scan' to run Snyk tests against images to find vulnerabilities and learn how to fix them

[thaJeztah]

I think you made a typo somewhere; (apline instead of alpine);

docker.io/library/node:12-apline

[thaJeztah]

I don't think there's a bug to fix here (see above), so let me go ahead and close this ticket, but feel free to continue the conversation

[Applequist]

Oh gosh how embarrasing... They say to not copy/paste huh... I'll have to had that one in my vim abbreviation.

However am I still allowed to suggest a clearer error message? I have google that thing before creating an issue (I promise) and one I found in docker buildx (?) gave similar error message but was either fixed by login in or changing dns setting...

Any way thanks for looking into it

[thaJeztah]

Yes, buildkit's errors are both "verbose", and somewhat confusing (hard to find the underlying error); see my comment on https://github.com/docker/buildx/issues/415#issuecomment-831885487. I think there's a tracking issue somewhere in the buildkit repository for this (improving error messages), but I can't find it (perhaps it's not there, and I should create one).

Looking at this typo maybe this could be improved by checking flavors too for suggestions like it does in https://github.com/moby/buildkit/pull/2218 for some images. cc @tonistiigi

moby/buildkit#1472

Yeah, there's also https://github.com/moby/buildkit/issues/2176 and https://github.com/moby/buildkit/issues/799. I think https://github.com/moby/buildkit/issues/1472 may be a bit too "broad", as it's also (IIRC) for "debugging intermediate builds steps, etc. Perhaps we need a tracking issue / epic specifically about errors.
