How to build on arm?

[kx1t]

I'm trying to build the standard container (https://github.com/Zenika/alpine-chrome/blob/master/Dockerfile) on arm (Raspberry Pi 3B+ and 4B) to use as a basis for a screenshotting service I'm writing, but I can't get it to build. It complains that chromium doesn't exist as part of the apk add execution.

Specifically, I'm using docker buildx to armhf and arm64 containers.

Is this supported? Anyone have any experience or suggestions on how to build the container successfully?

Thanks!

I was able to build my own container based on Debian-Slim. Builds and works in armhf/arm64 for headless use of chromium, but I can't say that chromium is very stable. About half of the time, the command never returns when requesting a screenshot.
In any case, that's an unrelated issue.
No further need for this issue, I'll close it.
