Node Taints and Affinities

Component Category

Cluster operations / scheduling and placement

Component Description

Node taints, tolerations, and affinities are Kubernetes scheduling controls used to steer workloads onto the right nodes.

Why It Is Used

In BullSequana AI Runtime, these controls help reserve specialized hardware for the workloads that need it most. They are especially important for GPU inference, high-storage services, and other components that should not compete with general-purpose workloads for the wrong node types.

• Kubernetes taints and tolerations
• Kubernetes node affinity

Interacts With

• KubeAI, vLLM, and Faster Whisper, which often need GPU-aware scheduling.
• MinIO and PostgreSQL, when storage-heavy workloads should be steered to specific nodes.
• Prometheus and Grafana, which help operators verify workload placement and resource behavior after scheduling rules are applied.
