This app configuration provides access to a Jupyter Lab environment running inside of an Apptainer container.
This app uses Spack for package management to load an
Apptainer container. If this software is already
configured on your compute nodes, you can remove this load step. Otherwise,
ensure that the script will load your spack environment, and that you have an
environment configured for apptainer. Spack environments are preferred over
loading modules directly. Environments provide consistency by articulating the
concretized stack of packages to load, and they provide flexibility in that one
can update the environment to update packages without needing to update the app
configuration to load new packages. A sample configuration is included at
spack-environment/apptainer/spack.yml
The form.yml file provides a list of valid apptainer containers that a user
can select from. The containers in the form.yml correspond to the apptainer
definition files in the build directory. The location where .sif files are
stored is defined in the [template/script.sh.erb] file.
These images can be built with apptainer commands, such as
apptainer build /shared/sif/scipy-notebook.sif build/scipy-notebook.def
