Vantage6, a powerful platform for privacy-preserving analysis in the life-sciences domain, employs Docker in its data nodes when performing tasks like federated learning. This tight bond to Docker poses challenges on infrastructure security, efficient computing resources usage, and integration of alternative container technologies. To overcome these challenges, we explored the integration of Kubernetes into vantage6 through a Proof-of-Concept (PoC) approach. The PoC designed and implemented a Kubernetes-based architecture for vantage6, which can be easily deployed on a single machine or a cluster. This PoC serves as the reference to accelerate the adoption of Kubernetes in vantage6.
