$ ./ci/docker-run-ci TA_PYTHON=OFF ENABLE_CUDA=ON all check
Removing previous build container: andrey.tiledarray.build

Running new build of /home/andrey/github/tiledarray on andrey.tiledarray.build
* Use CTRL-p CTRL-q to dettach
* To reattach use: docker start -a -i andrey.tiledarray.build
...

This builds targets all check on current Git branch in a docker container named ${USER}.$(basename $PWD).build
