title: what is the purpose of conda inside a container?
body: <p>I have seen many examples of dockerfiles with conda commands in them. And there are pre-build anaconda and miniconda containers. I must be missing something. </p>
  
  <p>Doesn't docker REPLACE virtualenv and conda? Shouldn't I have all of my dependencies right in my dockerfile? I don't understand what I gain from adding anaconda here. In fact it seems like it makes my container unnecessarily bigger if I have to pull a miniconda container if Im not using all of miniconda's included modules.</p>
