Hi all, I opened this ticket recently, but think it needs further discussion. https://issues.apache.org/jira/browse/IGNITE-16293 <https://issues.apache.org/jira/browse/IGNITE-16293>
The motivation for the ticket came from a user request for an image that ran natively on an M1 MacBook (70695484 <https://stackoverflow.com/questions/70685637/apache-ignite-docker-image-not-compatible-on-apple-m1-max/70695484#70695484>). I’m honestly quite surprised that it’s taken this long for anyone to ask! I’ve run Ignite on my Raspberry Pi from time-to-time and ARM-based servers are also becoming increasingly common. However, this question led me down a rabbit-hole, resulting in three further questions: Should we support Docker images with architectures other than x86-64? If yes, which ones? And how should we support them? We currently have images for x86-64 and, for a couple of versions, additional images for s390x. So one argument in favour of the first point is that we already do! Of course, extra code requires more support and some work on the build servers. I think the effort is low but it’s non-zero. I don’t think we need to go crazy here. I think adding an ARM image would open up support for Raspberry Pi’s and Apple Silicon Macs. Docker also has the ability to cross-compile (working-with-buildx <https://docs.docker.com/buildx/working-with-buildx/>) so there’s no need for any specialised new hardware. (I’m unsure if this option works for s390x?) Currently, our cross-platform support is achieved just with tags. There is a better way where, in addition to the tags, you add a manifest. The manifest allows a client to pick the right image automatically. (multi-platform-docker-builds <https://www.docker.com/blog/multi-platform-docker-builds/>) As an example, when I run this on my Raspberry Pi I get the ARMv7 image: sudo docker run -it --rm --net=host ghcr.io/sdarlington/ignite-arm:2.12.0 But if I run the same command on an Apple Silicon Mac (I think — I don’t have one to test!), it would use the aarch64 image. I built both the ARMv7 and aarch64 images on my Intel Mac. Thoughts? Regards, Stephen
