apt-get install here omits --no-install-recommends (used in production Dockerfiles like Dockerfile.backend) and includes libxrender-dev (a build-time -dev package) which unnecessarily increases image size for a runtime container. Consider adding --no-install-recommends and switching to the runtime library package where possible.
