Python

This directory contains Dockerfiles for building images based on CentOS 7 that run Python for different purposes.

To run GUI applications (e.g. Python with interactive plotting) in docker, first create a non-root user in the docker image.
The image/container user name should be the same as the $USER that will run the container on the host machine. The uid/gid
of the user in container should also be identical to the one on the host; otherwise usermod and groupmod commands are
needed to alter them.

Refer to python/2.7/Makefile for building an image "python" with a regular user.

Next give only containers of $USER permission to access the X11 socket on the local host machine, and run a container with
mounted X11 socket and explicitly specified user name.

xhost +si:localuser:$USER
docker run -it --rm -e DISPLAY=$DISPLAY -u $USER -v /tmp/.X11-unix:/tmp/.X11-unix -v $PWD:$PWD -w $PWD --entrypoint=/bin/bash DockerImage
xhost -si:localuser:$USER

The run-time -u or --user option can be skipped if the image's Dockerfile already sets a user name using USER.

To run a password-protected notebook in daemon mode, use the following command. To allow public access to this notebook, remove the
loopback IP (127.0.0.1:) from the run command. Local-only access is preferred for safety.

docker run -it -d -p 127.0.0.1:443:8888 -e PASSWORD=MakeAPassword -v $PWD:/notebook --entrypoint=/run.sh DockerImage

To run a password-protected notebook in attached mode, use the following commands.

docker run -it --rm -p 127.0.0.1:443:8888 -v $PWD:/notebook --entrypoint=/bin/bash DockerImage

In the docker process, run PASSWORD=MakeAPassword /run.sh & to start the Jupyter notebook in background.
