Building OCI images efficiently is at the core of modern cloud-native workflows. In this lightning talk, I'll compare two common approaches - Source-to-Image (S2I) and Paketo Buildpacks - focusing on how they construct OCI images, their trade-offs in transparency, reproducibility, and developer experience, and what this means in practice. I'll briefly illustrate our experience applying both methods to Python (acc-py) environments and how these images integrate with a Knative-based platform at CERN..
