Dockerfile

# This Dockerfile can be used to run Mesh2HRTF inside a Docker container.
# Some information on how the container can be generated are given below. For
# more information refer to docker.com
#
# Inside the container you can
# - Run the `hrtf_mesh_grading`
# - Run numerical simualtions with the `NumCalc` command
# - Access the Mesh2HRTF Python API, e.g. by running `python3` and then
#   `import mesh2hrtf`
#
# You can build the container in the command line by executing
# `docker build --tag ubuntu:mesh2hrtf .` (without the ` signs)
#
# Start the container with out an external volume with:
# `docker run -dit --name mesh2hrtf ubuntu:mesh2hrtf /bin/bash`
#
# Start the container with an external volume mounted at /home/data:
# `docker run -dit --name mesh2hrtf -v '/local/folder:/home/data' ubuntu:mesh2hrtf /bin/bash`
