Kubernetes Primer: Dynamic Resource Allocation (DRA) for GPU Workloads

In the previous article, I introduced Device Plugin and GPU Operator to expose the underlying accelerated infrastructure to Kubernetes workloads. In this article, I will introduce an emerging feature of Kubernetes called Dynamic Resource Allocation (DRA) that makes GPU orchestration efficient.

Traditional Kubernetes resource management was designed around simple countable resources like CPU and memory. This model worked well for general computing but struggled with specialized hardware such as GPUs and purpose-built AI accelerators.

The…
