A collection of Singularity (Apptainer) definition files.

This repository helps you build Apptainer containers on an HPC system using SLURM.

Because SLURM setups vary across HPC systems, this repository does not include a static build script. Instead, it allows you to quickly generate one using your own configuration.

Steps to Build a Container

1. Create config

   In the root of the repository, create a file called build.conf. This file defines your SLURM resource requests such as time, CPUs, memory, etc.

   To get started, copy an example from the config examples folder:

   cp config_examples/hpc1_build.conf build.conf

2. Generate the build script

   Run the following command from the root directory:

   make

3. Submit the container build job

   To build a container, run the build script and pass the name of your definition file (without the .def extension):

   sbatch build.sh <container_name>

   This will build <container_name>.sif from <container_name>.def and place the output in your $PROJECTDIR/containers/ directory. If PROJECTDIR is not set the container will be put in the current directory.
