In a large cluster, you don’t want ‘general’ workloads running on your expensive GPU nodes or high-security master nodes.
The Logic:
– Taint: Applied to a Node (“Only special pods allowed here”).
– Toleration: Applied to a Pod (“I am allowed to run on that special node”).
– Taint: Applied to a Node (“Only special pods allowed here”).
– Toleration: Applied to a Pod (“I am allowed to run on that special node”).
This is the foundation of multi-tenant cluster management and hardware-specific scheduling.
