To optimize the Docker image size and follow best practices, it's recommended to use the --no-install-recommends flag with apt-get install. This prevents the installation of packages that are not strictly necessary for the main packages to function.

RUN apt-get update && apt-get install -y --no-install-recommends \
    curl \
    zstd && \
    rm -rf /var/lib/apt/lists/*

To improve efficiency and avoid creating an intermediate file on the filesystem, you can pipe the output of curl directly into tar. This makes the command cleaner and avoids the need for a separate rm step.

    curl -L "https://ollama.com/download/ollama-linux-${OLLAMA_ARCH}.tar.zst" | tar --zstd -x -C /usr
