pyROOT_with_python3_Dockerfile

Readme.md

I wanted to compile cernroot on ubuntu with python3 bindings for ROOT (pyROOT).

This is what worked for me (Dockerfile)

Let’s go ahead and test it:

Build the docker:

mkdir pyROOT_docker
cd pyROOT_docker
wget https://gist.github.com/acidbourbon/48fdc0df540614c11238a9e6765be3ae/raw/cad9e530ac83b4fcab2323307146a5ef0ffeee49/Dockerfile
docker build -t pyROOT_docker .

Run the docker (with x11 support)

docker run -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix \
--name pyROOT_docker -v $(pwd)/workdir:/workdir \
--rm -it --user $(id -u) pyROOT_docker /bin/bash

Test the installation inside the docker:

micha@5be8c924103b:/$ . /root-build/bin/thisroot.sh
micha@5be8c924103b:/$ python3

... a TBrowser window opens ... win!
