FR: Support for ARM64

[lindermayr]

Most of my Docker containers run on Raspberry Pi or in a free instance of Oracle Cloud. Unfortunately, they only support ARM64, so your software always exits with this error: exec /docker-entrypoint.sh: exec format error

I've found some instructions for adding multiple platform support, but in lack of programming skills, I cant do it on my own:
https://docs.docker.com/build/building/multi-platform/

Do you think it'd be possible to tweak your software to play nice with different architectures like ARM64? That'd be a huge help!

So fair warning, I haven't tested this at all. But I pushed some ARM builds under the edge tag.
In this line of the docker compose add the edge tag to pull the right image, then run the container as normal.
image: mpdcampbell/traefik-geoip-filter:edge

Let me know if works or not, when I have more time I'll test it on a Raspberry Pi.

Yes, seems to start. Thanks for the fast support.

It seems that it can't read the environment variable:

This is my Docker-Compose:

geoipfilter:
image: mpdcampbell/traefik-geoip-filter:edge
 container_name: geoipfilter
    volumes:
         - ./geoip:/geoip
      environment:
         - MAXMIND_ID="0099999"
         - MAXMIND_KEY="blabla"
         - FILTER_TYPE="allow"
         - COUNTRY_CODES=FR
         

For testing you could also use a free ARM-VM (4 cores with 24G RAM) from Oracle: https://www.oracle.com/cloud/free/
