Elmer build apparatuses for various Linux distros using docker Dockerfiles

Currently ubuntu-focal and debian-buster work fine. Others are remnants of past.

Usage:

• Set env variable ELMER_SOURCE_DIR point at elmer source directory.
• Run make build-<flavor> where <flavor> corresponds to Dockerfile-<flavor> and precaches/opts-<flavor>.cmake
  • You can also do make conf-<flavor> to run cmake only or make bash-<flavor> to explore build environment.
• A special contained setup (initially only for ubuntu-focal) for using Docker to actually run Elmer simulations on your system is built by make runenv-<flavor>
  • This creates an image that contains an MPI-enabled Elmer installation that can be used to run Elmer simulations. Provided you are in the subdirectory where the input files reside, do a

  $ docker run -it -v $(pwd -LP):/home elmer-runenv-ubuntu-focal /usr/local/elmer/bin/ElmerSolver nameofyour.sif

  • or in case of a parallel MPI run (here with 6 processes)

  $ docker run -it -v $(pwd -LP):/home elmer-runenv-ubuntu-focal mpirun --allow-run-as-root -np 6 /usr/local/elmer/bin/ElmerSolver nameofyour.sif

TODO

• Build ElmerGUI separately or make elmergui build variants
• ctest runs
