In practice, one can check the Dockerfile lineage of a given Docker image and assess the quality of the commands. Good practices are to use package managers with explicit versions, for example "apt-get install subversion-tools=1.3.2-5~bpo1". Or, if you so desire, just pipe NixOS outputs into Docker, as somebody else in this thread mentioned.
