How do I build a new container from a definition file?

You can use the 'ujust apptainer build' command with the --image flag pointing to your .def file and the --tag flag specifying your output .sif filename.

Where are my Apptainer images stored by default?

Images pulled or managed through the bazzite-ai-pod system are typically stored in ~/.local/share/apptainer/.

Does this skill support both NVIDIA and AMD GPUs?

Yes, the skill automatically detects the host GPU and applies the appropriate flags (--nv for NVIDIA or --rocm for AMD) during container execution.

What is the difference between Apptainer and Docker?

Apptainer is designed specifically for High-Performance Computing (HPC). Unlike Docker, it runs containers as the user (no root required), uses single-file SIF images, and is compatible with shared file systems common in clusters.

Deployment & DevOps

Manages Apptainer containers for HPC workloads with automatic GPU passthrough and SIF image handling.

The Apptainer skill empowers Claude to handle high-performance computing (HPC) container workflows using the Apptainer (formerly Singularity) standard. It simplifies the lifecycle of SIF images, allowing users to pull from registries like Docker Hub and NVIDIA NGC, build custom images from definition files, and run workloads with automatic NVIDIA/AMD GPU detection. This skill is ideal for researchers and developers who need rootless, portable container solutions for scientific computing, AI training, and cluster-based environments.
