NAME

deb2apptainer - Build a Singularity/Apptainer image with given Debian packages

SYNOPSIS

deb2apptainer [-hB][-c CMD][-f FROM][-n NAME][-o DIR][-p deb2singularity [-hB][-c CMD][-f FROM][-n NAME][-o DIR][-p PRE_SCRIPT][-s POST_SCRIPT] packages

DESCRIPTION

deb2apptainer is a simple script which takes as input a list of Debian packages and generates automatically a Singularity/Apptainer container including these packages. A set of freedesktop.org desktop launchers are also generated based on the .desktop and icon files found in the packages. In addition, a desktop launcher is created to start the container in a Terminal.

This tool is suited for deploying applications as containers, as well as for testing Debian packages in a sandbox.

A Desktop launcher is created as /tmp/xeyes/launchers/x11-apps-terminal.desktop

deb2apptainer x11-apps meshlab
echo “sed -i `s/main/main contrib non-free/g' /etc/apt/sources.list” > pre.sh
deb2apptainer -p pre.sh x11-apps
echo “echo `deb http://deb.debian.org/debian bullseye main contrib non-free' >> /etc/apt/sources.list” > pre-script.sh
deb2apptainer -n pyhst2 -f debian:bullseye -p pre-script.sh -o /tmp/apptainer-pyhst2/ python3-pyhst2-cuda nvidia-smi nvidia-cuda-toolkit
apptainer run –nv /tmp/apptainer-pyhst2/pyhst2.sif nvidia-smi ```
