The 1.21.1-alpine tag on Docker Hub is missing multple OS/ARCH entries

[JonasAlfredsson]

Hi,

I am building an image for multiple architectures from this image and ran into the following error for the linux/386 platform when building from the 1.21.1-alpine tag:

error: failed to solve: rpc error: code = Unknown desc = failed to solve with frontend dockerfile.v0: failed to create LLB definition: no match for platform in manifest

Looking at it on Docker Hub we indeed see that it is only available for the following architectures:

• linux/arm64/v8
• linux/arm/v7
• linux/arm/v6
• linux/amd64

This is very weird since the 1.21-alpine tag has also the following ones:

• linux/ppc64le
• linux/s390x
• linux/386

so something must have gone wring in the push that was made.

The x86 issue is known as there is no mercurial anymore in alpine 3.14 for this architecture. Maybe we should do something about it, but I'd rather wait for alpine to sort it out on their own.

For ppc64le and s390x it seems Docker Library builders are stuck/unavailable, so there isnt much we can do at this moment.

Thanks for the swift response.
Glad that this is a known issue, but I am a little bit unsure what this means. Will Alpine stop serving x86 builds of Nginx and this ARCH should be dropped from my automated builds?

[yosifkit]

make: mkdir: Operation not permitted

s390x and ppc64le are likely to be suffering the same bug as our php image builds docker-library/php#1178 (comment).

[tianon]

This is fixed for ppc64le and s390x -- for i386, I'm not convinced it's going to be, but maybe? 🤷 😅

[JonasAlfredsson]

That is some good news, thanks for posting the update :)
However, what are the plans for 386 going forward? Should this issue remain open, or will that arch be discontinued for Alpine?

Is this issue causing this one?
goharbor/harbor#15739

[tianon]

Yep, looks pretty likely to me.

Fixed in nginx:1.21.4 for Debian and in nginx:1.21.4-alpine for Alpine.

It seems like there are still some issues. For example nginx:1.21.4 is missing linux/386 even though it's available for nginx:1.21.

[thresheek]

Hmm, interesting. @yosifkit @tianon ^^^ can you elaborate why that could have happened?

[yosifkit]

It is failing to find the nginx package on i386. The binary-i386 directory seems to be missing on the apt repo for bullseye (but is there for buster): https://nginx.org/packages/mainline/debian/dists/bullseye/nginx/, so it is not getting a Packages.gz list. The desired version of .deb files do exist in the pool/nginx/n/ folders.

Ah that makes sense. I saw that the tag for 1.21 was updated and assumed it was 1.21.4, but it's actually still 1.21.3 for i386 (it was updated for all other archs) https://hub.docker.com/layers/nginx/library/nginx/1.21/images/sha256-387da9849102b73c06e645a8f0f40c72fae755f20d33391596041a4dcf8284a9?context=explore

[thresheek]

Ok, should be fixed with todays images for 1.21.1 and 1.20.2.
