An internal service is halfway through a Python-to-Go rewrite: the amd64 build already runs the new Go code while arm64 still ships the legacy Python one - same API, two completely different codebases and Dockerfiles. Can you build and push a single multi-platform image from the two independent single-platform variants?
Learn how to build container images for non-native CPU architectures by offloading the build to a remote machine using Docker Buildx.
Combine your knowledge of QEMU emulation, cross-compilation, and remote builders to build and push a multi-platform container image (linux/amd64 + linux/arm64) to a registry.
Learn how to build container images for non-native CPU architectures using Go's support of cross-compilation.
Learn how to build container images for non-native CPU architectures (e.g., arm64 on an amd64 host) using QEMU user-space emulation and Docker.
