Clean up and keep only one version.

[luca-heltai]

Following @tjhei advice, I'd like to clean this repository, and keep only very few versions of deal.II around. I think it is now reasonable to stick only to candi for the full version.

I propose to keep only the following images with the given Dockerfile showing the dependencies

• dealii/ubuntu16
  • dealii/base:gcc-serial
    • dealii/base:gcc-mpi
      • dealii/base:candi
        • dealii/dealii:v8.5.0-gcc-candi-debugrelease
        • dealii/dealii:vX.X.X-gcc-candi-debugrelease (using --build-arg VER=vX.X.X)
  • dealii/base:clang-serial
    • dealii/dealii:v8.5.0-clang-debugrelease
    • dealii/dealii:vX.X.X-clang-debugrelease (using --build-arg VER=vX.X.X)

What you do you think? Any other suggestion/opinion on the naming structure?

[tjhei]

1. Should we include the word "serial" or "min" or something in the name for the last two images? This could be the same as we will do for the macosx installers.
2. I am fine with removing "-candi" from the name of the full images
3. VER=vX.X.X - here master also works, right?

1+2: How about this:

dealii/dealii:latest = dealii:v8.5.0-gcc-mpi

dealii/dealii:v8.5.0-clang-serial (bare deal.II, serial, both debug and release)
dealii/dealii:v8.5.0-gcc-serial (bare deal.II, serial, both debug and release)
dealii/dealii:v8.5.0-gcc-mpi (all possible dependencies, both debug and release)
dealii/dealii:v8.5.0-gcc-mpi (all possible dependencies, both debug and release)

and possibly, for smaller images:

dealii/dealii:v8.5.0-clang-serial-debug
dealii/dealii:v8.5.0-clang-serial-release
dealii/dealii:v8.5.0-gcc-mpi-debug
dealii/dealii:v8.5.0-gcc-mpi-release

3. Yes, but that changes in time. I'd use short sha1 for specific releases, i.e.,

f0ce4e9-clang-serial-release
f0ce4e9-clang-serial-debug

This would require a total of 4 Docker files: gcc-serial, gcc-mpi, clang-serial and clang-mpi, with two build args: VER, and BUILD_TYPE. These files should be identical except for the FROM instruction (unless we want to explicitly turn on all features, in which case also the deal.II build command should be different).

maybe we could replace serial and mpi with minimal and full. It is obvious that minimal is serial (with no external deps) and full is parallel, with all dependencies. Comments?
