What You'll Learn

  1. Restrict pods to specific nodes with node selectors and matching labels.
  2. Use node and pod affinity to co-locate workloads or keep them apart.
  3. Manage placement with priority classes, topology spread constraints, scheduling gates, and dynamic resource allocation.

A deep dive into Kubernetes pod scheduling, from nodeName and node selectors through node and pod affinity, topology spread constraints, priority classes and preemption, plus alpha features like scheduling gates and dynamic resource allocation.
