Add multiarch builds of the image / container

[Sebastix]

The current image / container is only build for arm architectures.
To use it on your Rasperry Pi or other Linux architecture, the image should also be compatible with amd/x64 architectures.

Hi @Sebastix, are you planning to work on this ? I'm very interested about this feature.

@emze9 Good question! My honest answer is that I've not planned time to work on the project due other work of clients. It's on my long list together with a lot of other things.
Do you know how to build an image on your machine where you would like to use the software? You can find these steps in the README.md. Using your own build image should work.

cd ~
git clone https://github.com/Sebastix/crypto-dca.git
cd crypto-dca
docker build . -t ghcr.io/sebastix/crypto-dca:latest

Thanks for your answer @Sebastix !

I've forked your project on my Gitlab and tried to build a new image with a CI Job. My Gitlab Runner has an amd64 cpu and despite of some errors that I've fixed, I was able to build a new image. But when I ran the container, I got an error exec format error. It's related to the cpu architecture. I admit that i didn't look any further because of the little time I had ^^

Maybe this resource helps you out: https://www.docker.com/blog/multi-arch-build-what-about-gitlab-ci/ for a multi-arch build in your Gitlab CD/CI.

You could also try to build the image on the machine where you would like to run the tool.
