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?
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.
Save a container image as an OCI layout, extract its filesystem layers, and mount them together using OverlayFS to get a flat container-like rootfs.
Learn how to build a secure, lightweight, and production-ready Python container image for a FastAPI application by following this hands-on challenge full of practical tips and tricks. Solutions for pip + venv, poetry, and uv are included.
Challenges contributed by the community members sharing their knowledge and expertise.
Combine multi-stage builds, build-time arguments, non-root users, and Pod security context into a single production-grade image pipeline.
