This is the repository of the Docker container used for Pandora's Travis CI.

The PandoraMonitoring and LArReco builds depend upon a binary of ROOT built against C++17.

In the event that you have to rebuild the docker container, please note that the Dockerfile references a tarball containing a suitable ROOT build. This file cannot be stored in the github repository, but can be found within the /storage/dune/docker folder on Warwick CSC.

This file should be copied to the folder containing Dockerfile in order to rebuild the container.

The tarball noted above was built within an equivalent docker container without the ROOT tarball using the following commands

cd /
git clone https://github.com/root-project/root.git
cd root
git checkout -b v6-18-04 v6-18-04
mkdir obj
cd obj
cmake -DCMAKE_INSTALL_PREFIX=/pandora/root -DCMAKE_CXX_STANDARD=17 \
   -Dgminimal=ON -Dbuiltin_glew=ON -Dbuiltin_ftgl=ON \
   -Dopengl=ON -Dbuiltin_gl2ps=ON ..
make -j2 install
cd /pandora
tar czf root6-18-04.tar.gz root

To extract the tarball from the docker instance, in a separate terminal run

docker ps

This will tell you the docker process ID for the container in which you created the tarball, which you can then use to extract the tarball via

docker cp <ps_id>:/pandora/root6-18-04.tar.gz .

The docker container can be built using the following command

docker build -t pandorapfa .

To push the container to Docker

docker login
docker tag pandorapfa pandorapfa/pandorapfa_c17
docker push pandorapfa/pandorapfa_c17
