Docker image does not support arm64/Raspberry Pi

[ghost]

I'm trying to run this image to build a jekyll site on a Raspberry Pi 4B (https://www.raspberrypi.com/products/raspberry-pi-4-model-b/) which runs on the aarm64 architecture.

Using docker run -v $(pwd):/srv/jekyll -p 4000:4000 -it jekyll/jekyll:latest jekyll serve will download the image but fail with:

Status: Downloaded newer image for jekyll/jekyll:latest
WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
standard_init_linux.go:228: exec user process caused: exec format error

Installing jekyll on the host, building the site, and running an apache docker image works because the httpd-alpine images support arm64. This method is not preferred because changes to the site require the image to be rebuilt and relaunched for every change.

This is also an issue on M1 macs; Docker for Mac has an Amd64-emulation layer, but it is pretty slow.
