Arm64 support?

[michelcve]

Is this supposed to work on arm64 as well? I'm trying to install on a few Pi 4 8GB's with Fedora Core OS and k8s 1.21.

Never tried that :)

You have to compile Dockerfiles for arm64 architecture, but I'm not sure if all the build deps for for linstor-controller and linstor-satellite will be available on arm64

[michelcve]

Hmm, tried the linstor-controller, but it indeed fails

Interesting, I think you can create an issue on upstream project and ask if the LINSTOR and DRBD stack are tested on arm64 arcitecture

[michelcve]

Already did https://github.com/kvaps/kube-linstor/issues/44

Although on their private customer only repo they claim to have ARM64 builds according to this tweet https://twitter.com/linbit/status/1258728911464214533

[michelcve]

Okay, I've looked into it a bit, and the problem comes from the build.gradle being hardcoded to download and use an x86_64 binary of protoc.

A dirty fix for this would be adding the following to dockerfiles/linstor-controller/Dockerfile (after the git checkout, and just before the RUN make debrelease)

RUN sed -i 's/x86_64/aarch_64/' build.gradle
RUN git stage build.gradle
RUN git config --global user.email "you@example.com"
RUN git config --global user.name "Your Name"
RUN git commit -m "fix for aarch64"

This gets me past the previous error. Unfortunaty I ran out of disk space, so I couldn't complete the entire build, but it was almost complete (so I this this should fix it for arm, although dirty) :-)

B.t.w.: The git commit is required, or gradle will complain.
