  GitHub is a popular repository for hosting software projects, both due to
ease of use and the seamless integration with its testing environment. Native
GitHub Actions make it easy for software developers to validate new commits and
have confidence that new code does not introduce major bugs. The freely
available test environments are limited to only a few popular setups but can be
extended with custom Action Runners. Our team had access to a Kubernetes
cluster with GPU accelerators, so we explored the feasibility of automatically
deploying GPU-providing runners there. All available Kubernetes-based setups,
however, require cluster-admin level privileges. To address this problem, we
developed a simple custom setup that operates in a completely unprivileged
manner. In this paper we provide a summary description of the setup and our
experience using it in the context of two Knight lab projects on the Prototype
National Research Platform system.
