docker for raspberrypi

[ashjas]

Please consider creating a docker image for raspberrypi.

It's currently possible to build the Docker image manually for arm32v7/armhf, but the Docker Hub image is amd64 only and that's not ideal. I'll see if I can somehow configure the automated Docker Hub builds to build multiarch images. This should add support for the official image for Raspberry Pi as well.

Finally after a lot of failing builds, I've managed to set up the bilde2910/hauk:latest tag as multiarch. The Docker Hub image is now built for the following architectures:

• amd64 - standard x86_64 servers, built natively
• arm32v7/arm/v7 - 32-bit ARM (e.g. Raspberry Pi 2 and 3), built with QEMU
• arm64v8/arm64 - 64-bit ARM (e.g. Raspberry Pi 4), built with QEMU

This means that the standard image on Docker Hub will now work on Raspberry Pi the same as on standard x86_64 processors. I've tested and confirmed it works on my Raspberry Pi 3B+. QEMU is used for building only, and is removed from the container image before publication on Docker Hub.

If you wish to build it yourself, you should still use the main Dockerfile in the root of the repository. The Dockerfiles in the docker directory are meant for use with Docker Hub.
