This project has multiple versions of EnergyPlus ready for use in a single container.
To run EnergyPlus you should either mount your directory into the container or create a dependent container where you call ADD . /var/simdata/energyplus.
To mount the local folder and run EnergyPlus (on Linux only) make sure that your simulation directory is the current directory and run:
docker run -it --rm -v $(pwd):/var/simdata/energyplus nrel/energyplus EnergyPlus
