I am very pleased that you provide docker images of bioconductor, I think this is a huge added value for your users.
I may have missed something, but it seems that they are some missing information in the docker tags.
From what I understood, there is no easy way to get a docker for one specific bioconductor release.
I mean, today, if I get bioconductor/release_base it will be the 3.1 version. But in 6 months it will be probably the 3.2 version. Moreover what if I want to reproduce someone's bug in the 3.0 version ? I suppose it is possible based on dates, but it could get quite cumbersome.
That's why I guess that adding some simple tags such as: v3.1:date and v3.1:latest could prove very useful.
Say that I want to get the (current) latest 3.1 version:
docker run bioconductor/release_base:v3.1
if I want the latest 3.0:
docker run bioconductor/release_base:v3.0
Moreover, why not providing a release_all, containing all packages ?
