(Run everything as root)
- Install dev tools:
yum groupinstall "Development Tools" - clone the repo:
git clone https://github.com/singularityware/singularity.git - start the build:
cd singularity
./autogen.sh
./configure --prefix=/usr/local --sysconfdir=/etc
make
make install
- create a 6GiB image, big enough to contain feelpp-toolboxes, in a common place that is readable by users:
mkdir /singularity
singularity create --size 6000 /singularity/feelpp.img
-
import the current feelpp-toolboxes from dockerhub (it will download roughly 6 GiB so it might take a while):
singularity --verbose import /singularity/feelpp.img docker://feelpp/feelpp-toolboxes:latest -
start a singularity shell without bindings and with write support:
singularity shell -w /singularity/feelpp.img -
move the feelpp files away from the $HOME dir, since singularity will bind the users actual $HOME over that:
mkdir -p /opt
mv /home/feelpp /opt/
exit
An example runscript:
#!/bin/sh
# Set Feel++ env vars
# write output files to the feel dir in users $HOME

Save this as runscript.sh, make it runnable and then run as:
singularity exec /singularity/feelpp.img ./runscript.sh
