Usage: build_docker_image.sh [options] [-- [cmake_args]...]
Available options:
General:
-h|--help show this help message
Docker-specific:
-s|--source image source dir (i.e. debian8, nvidia-cuda, etc)
-d|--docker-repository docker repository for the image
-t|--docker-tag docker tag for the image
Required options: --source and --docker-repository.
For example, running:
$ build_docker_image.sh -s debian9 -d mydocker/debian9-clang -t latest
will produce two docker images:
mydocker/debian9-clang-build:latest - an intermediate image used to compile
clang.
mydocker/clang-debian9:latest - a small image with preinstalled clang.
Please note that this example produces a not very useful installation, since it
doesn't override CMake defaults, which produces a Debug and non-boostrapped
version of clang.
