## Summary Copy both `uv` and `uvx` into place in a single Dockerfile command. [`COPY` supports multiple sources when the destination is a directory.](https://docs.docker.com/engine/reference/builder/#copy) As it is, e.g. `ghcr.io/astral-sh/uv:0.4.16-python3.12-bookworm-slim` has this (screenshot from [Dive](https://github.com/wagoodman/dive)): <img width="377" alt="Screenshot 2024-09-26 at 10 11 24" src="https://github.com/user-attachments/assets/1ca6a0d5-95fd-4210-9a4f-0afa2300b63f"> and less layers is a Good Thing. ## Test Plan I hope the CI pipeline will take care of testing – I couldn't get the Docker build to finish on my machine right away (SIGKILL, so out of memory, I guess 😄)
