Build on arm64

[multani]

Cf. #38

Nomad still needs the glibc and it's difficult to find a maintained glibc package for Alpine, built for arm64. So, this switches the base image from Alpine to Debian.

Quick testing shows the new base image adds 60 MB:

$ docker images | grep nomad
local/nomad       debian         702bf83325e9   15 minutes ago      211MB
local/nomad       alpine         96d0438abfd1   15 minutes ago      149MB

👋 Hey @multani, any updates on this? I was looking for a nomad container built for arm, and came across this.

Hey @Mongey 👋

This is a bit on hold for now, as Nomad needs the glibc and it's difficult to get it with Alpine. I'm not sure if switching over the base image from alpine to debian is a good move either at the moment, I'm not sure how the Docker image is used :D Maybe I should start a discussion about that 🤔

Otherwise, another possibility would be to build 2 different images:

• One Alpine-based, only available for x86-64
• Another one Debian-based, available for other platform (x86-64, but also arm64 and what else)

Would you be interested to help on this topic?

I intend to switch over the base image from Alpine to Debian: #133

[gbarton]

I see you started moving over to debian, what stopped you in the end? Was it just the image size increase? Am looking to run on arm and your packaging seems to be the most updated and maintained!

[multani]

Hey @gbarton, I didn't took the time to move this forward and got stuck with other changes I wanted to do.
I'll try to get back to it in in November 🙇

[gbarton]

I don't mind helping, what do I need to do other than to bring the arm branch up to current? Anything in progress you are trying to finish?

[multani]

I wanted to simplify the build process for all the branches and unify this in a single branch to bring arm64 for all the subsequent releases.
I also want to keep the Alpine based build for some time.

I have some work in progress on all of this, I'll bring it up in the coming weeks 👍

[gbarton]

Alright, if there is anything I can do let me know!

[multani]

I'll continue the work in other pull requests:

• Replace Alpine 3.18 by Debian 12 as the base image #201 will change the base image to Debian
• I'll create another pull request to change the build system to build the images on the supported platforms and publish the multi-arch images.

[multani]

The actual multi-arch build is in #202, it adds support for armv7 and arm64.

Latest versions are built using Debian and support armv7 and arm64 🎉
