  Linux container technologies such as Docker and Singularity offer
encapsulated environments for easy execution of software. In high performance
computing, this is especially important for evolving and complex software
stacks with conflicting dependencies that must co-exist. Singularity Registry
HPC ("shpc") was created as an effort to install containers in this environment
as modules, seamlessly allowing for typically hidden executables inside
containers to be presented to the user as commands, and as such significantly
simplifying the user experience. A remaining challenge, however, is deriving
the list of important executables in the container. In this work, we present
new automation and methods that allow for not only discovering new containers
in large community sets, but also deriving container entries with important
executables. With this work we have added over 8,000 containers from the
BioContainers community that can be maintained and updated by the software
automation over time. All software is publicly available on the GitHub
platform, and can be beneficial to container registries and infrastructure
providers for automatically generating container modules to lower the usage
entry barrier and improve user experience.
