The Github Actions virtual environments currently support x64 machines only: https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners#supported-runners-and-hardware-resources (Standard_DS2_v2 virtual machines in Microsoft Azure is all Intel Xeon) and the actions/runner-images#2552 tracking the addition of arm64 environments remains closed due to Azure limitation.

Although self-hosted arm{,64} runners seem to be possible, this is not the level of complexity I'd like to get into at this point.

@vladak Thank you for the update. Are you going to consider this in the near future?
Can this feature will be open?

[vladak]

Sure, this is valid request. I'd like to have arm64 OpenGrok Docker images myself. It's just I don't want to invest the resources into the automated arm/arm64 image builds right now.

It's actually pretty easy to build multiarch images on GitHub actions, it just might take a while:

Thanks for the link. Building in Qemu is certainly a possibility.
