Please provide ARMv8 images

Apple uses ARM in Macs since 2020.

A workaround is to add --platform=linux/amd64:

docker run --platform=linux/amd64 ... kjarosh/latex:2024.3 ...

That needs Rosetta 2 to be installed and enabled in Docker though.

You're right that both TeXLive and Alpine provide aarch64 versions, but the problem is that TeXLive does not provide aarch64 version with musl (which Alpine uses). The link to tug.org you posted (https://tug.org/texlive/doc.html#platforms) lists x86_64 as the only architecture with musl support.

So the options are currently to either:

1. do not use Alpine and use something with glibc, which would basically require a full rewrite of the image increasing its size,
2. use something different than Alpine for aarch64 images only, which would be weird,
3. somehow make TeXLive work with aarch64 and musl, that will probably require building TeXLive from sources and will make that support unofficial (assuming it even works).

To be honest building TeXLive from sources sounds interesting, but is a major feature to implement.

I'm thinking the easiest and cleanest way of providing texlive on Alpine aarch64 would be writing a custom APKBUILD for texlive and building it. There's an existing APKBUILD for texlive (https://gitlab.alpinelinux.org/alpine/aports/-/tree/master/community/texlive) but I cannot use it in any way as it's not licensed.
