RISC-V image is important

[xlmnxp]

when I search for a lot of docker images I found it not support risc-v for example wordpress (I successfully install it manually in ubuntu image) then I go to contribute to support risc-v for official wordpress image then I found they based on this image and it not support risc-v yet

Conceptually, I agree, but with the PHP image based on Debian, we'll unfortunately need to wait for RISC-V to become a fully supported architecture there (which IMO is prudent anyhow -- the things they require for that such as access to decent hardware for running on, a stable ISA standard, etc are all good things that users of this image would want as well 🙈). ❤️

@tianon RISC-V is officially supported by debian and ubuntu and ISA is stable and frozen
and you can use any cheap SBC support RISC-V like VisionFive or Nezha

It's not supported by Debian yet: https://wiki.debian.org/Ports/riscv64, https://wiki.debian.org/ArchiveQualification/riscv64

It's a "ports" architecture -- there's work being done to get enough hardware to make it a real official port and be supported beyond Debian Unstable/Experimental, but it's not there yet.

(I have an Unmatched that's used by https://github.com/docker-library/official-images and builds the riscv64 builds of https://hub.docker.com/_/debian -- I'm pretty familiar here 😅)

See also the links on docker-library/official-images#10502 for ways to get involved in Debian to push that forward.

(I believe Alpine is in a similar place -- riscv64 is supported in Alpine Edge, but not a release yet: https://gitlab.alpinelinux.org/alpine/aports/-/issues/13269)

Until both debian and alpine get stable support for riscv64, I've created riscv64 images of php here: https://hub.docker.com/r/danog/php
