Arm64 support

[JorritPosthuma]

Hi!

I was wondering if arm64 support is on your roadmap? A lot of downstream tools (Postgres, Mongo, Redis) support arm64, but the docker images published are amd64 only. Is it something you can/would like to support? Especially nowadays with ARM64 based AWS instances (Amazon EC2 A1) and the new Raspberry Pi 4, it becomes more and more useful :).

Thanks for your feedback. At this moment we do not have any ETA for arm64 platform. Right now we are focusing on expanding and improving our containers & Kubernetes Charts catalog.

Alright! Thanks for letting me know :). Is it possible to use normal Debian as base image? Or is that missing a lot?

[beltran-rubo]

Do you mean to replace FROM:minideb and use other Debian? It should work because minideb is just a small version of a Debian distribution but it is only supported a x86_64 architecture. The binaries for postgresql, mongo, redis, ... are also x86_64.

[JorritPosthuma]

Yes, that was the idea. Switch to FROM debian and if the Postgres binary is build as part of the Dockerfile, then that's it. But otherwise replace it with an arm64 build :).

[beltran-rubo]

In that case that would not work. The containers do not run the compilation at build time. The Postgres binaries or other component binaries are already compiled for x86_64 so will not work on top of arm64.

FYI, I just needed the same thing for provisioning multi-arch accelerator base containers, so I ended up just hacking up the build scripts, building it on amd64 and arm64 and manually constructing the manifest. There's now an adaptant/minideb multi-arch image that includes both.

It should be easy enough to hack up the scripts to use buildx, but I haven't had the time to look at this yet.

One concern would be whether that produced reproducible builds.

Does debian-slim have arm64 images?

[pmundt]

@james-w Yes, of course, there is no real difference in image size for the x86_64 and arm64 builds.

[james-w]

Yes, debian-slim has arm64 images, so that would be an option for anyone that wants minimial debian images for arm64 until minideb has support.
