ÜBERSICHT¶

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

BESCHREIBUNG¶

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.

BEISPIELE¶

Create a Singularity/Apptainer container with package x11-apps in directory /tmp/xeyes, and launch xeyes:

•

deb2apptainer -o /tmp/xeyes x11-apps

•

/tmp/xeyes/start xeyes

Create a Singularity/Apptainer container with x11-apps and meshlab

deb2apptainer x11-apps meshlab

Create a Singularity/Apptainer container making sure software channels are active:

•

echo “sed -i `s/main/main contrib non-free/g' /etc/apt/sources.list” > pre.sh

•

deb2apptainer -p pre.sh x11-apps

Create a Singularity/Apptainer container based on specific Debian version, and make use of the GPU:

•

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

•
