Hi All,

I use a number of third party git repositories for my OpenFOAM projects which in the past I have compiled directly on the HPC. Because of the ever increasing number of these I thought it would be perhaps better to creater a docker image that has everything already built and then just start new containers everytime I want to run something on the HPC. Firstly, does anyone already do this and how do you find it?

Secondly could anyone offer some advice on the Dockerfile? I found the one from Robin over at CFD Engine (thanks Robin!):

FROM ubuntu:focal

ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get update \
	&& apt-get install -y vim curl git sudo

RUN useradd --user-group --create-home --shell /bin/bash foam ;\
	echo "foam ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers

RUN curl -s https://dl.openfoam.com/add-debian-repo.sh | bash ;\
	apt-get install -y openfoam1912 openfoam1912-tutorials ;\
	rm -rf /var/lib/apt/lists/* ;\
	echo "source /usr/lib/openfoam/openfoam1912/etc/bashrc" >> ~foam/.bashrc ;\
	echo "export OMPI_MCA_btl_vader_single_copy_mechanism=none" >> ~foam/.bashrc

USER foam

if I wanted to clone a repo and then make it with the above how would I implement that? Something like:

FROM ubuntu:focal

ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get update \
	&& apt-get install -y vim curl git sudo

RUN useradd --user-group --create-home --shell /bin/bash foam ;\
	echo "foam ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers

RUN curl -s https://dl.openfoam.com/add-debian-repo.sh | bash ;\
	apt-get install -y openfoam1912 openfoam1912-tutorials ;\
	rm -rf /var/lib/apt/lists/* ;\
	echo "source /usr/lib/openfoam/openfoam1912/etc/bashrc" >> ~foam/.bashrc ;\
	echo "export OMPI_MCA_btl_vader_single_copy_mechanism=none" >> ~foam/.bashrc ;\
	git clone <git-repository> ;\
	cd <git repository> ;\
	./allwmake

USER foam

Be interested to discuss how others implement this kind of thing.

All the best,
Callum
