Support armv7l

[danpoltawski]

It'd be nice to support armv7l so can run on rpi4 (at least for simple dbs)

Hi Dan,

We currently cross-compile during the GHA build.

Do you know whether armv7l support is included in the arm arch? The php image is available for both arm64, and arm (https://hub.docker.com/_/php), but the Docker docs are impressively vague on the compatibility: https://docs.docker.com/desktop/multi-arch/ and the DockerHub official image include arm32v6, arm32v7, and arm64v8 but not arm. I'm assuming that the arm arch covers the 32-bit variants but I haven't been able to find anything to confirm and I don't have a spare Rpi4 hanging around to just check.

If you're able to submit a PR then I can review.

The php images are working - I just made a simplified dockerfile and was able to build from FROM php:8.0-apache-bullseye - although I note that the Moodle environment page warns about using 32bit php, not sure if that means there are big potential problems?

I'm ok building the arm32v7 architecture images, np with that.

Only question that I've about that is if we really need them, specifically for the Raspi... they have arm64 cpus since ages ago (2017 or earlier) and there are 64 OSs for many them... so current arm64[v8] builds should work without problem, isn't it?

Hello Everyone,

so current arm64[v8] builds should work without problem, isn't it?

Confirmed via moodlehq/moodle-docker#248 (comment).

HTH,
Matteo

I'm going to close this issue:

• confirmed as working
• Moodle 4.2 onwards no longer supports 32-bit anyway.
