I came across this fabulous resource from SADA on working with Arm64 CPUs (powered by Ampere Altra) on Google Compute. The repo goes into a lot of detail around all aspects of running Kubernetes applications on Arm64, including:

• Using Google Cloud Build to build containers containing your application for multiple architectures
• Provisioning a heterogeneous x86/aarch64 GKE cluster
• Scheduling containers to run on a specific architecture

This is an excellent resource for getting started with GKE and multi-arch containers! The next step after this tutorial would be to deploy a cloud native application like a containerized WordPress deployment into your hybrid cluster.

You can find more information about using GitHub Actions to build multi-arch containers from scratch on the SADA blog.
