Charliecloud is a lightweight, fully unprivileged, open source container implementation for HPC applications. It can handle the entire container workflow, including building images, pushing/pulling to registries, and dealing with accelerators like GPUs. We take a unique approach to containerization while remaining compatible with the broader container ecosystem where it matters.

Notable distinctions include: fully unprivileged end-to-end workflow, small code base with minimal dependencies, delegation of all security boundaries, layer-free build cache, zero-consistency root emulation based on seccomp, and a spirit of openness and public service.

This talk will motivate containers for HPC applications, then explain Charliecloud’s design philosophy and how we address these needs. We’ll discuss Charliecloud’s “weirdness” when compared to other implementations (i.e., its design philosophy and key distinctions), provide a brief overview of the code’s structure, and summarize recent and upcoming changes of interest.
