Kubernetes is a powerful platform for managing containerized applications across a cluster of nodes. However, sometimes you may want to have more control over which pods are scheduled on which nodes, for various reasons such as performance, security, or cost.

What are taints and tolerations?#

Taints and tolerations are a feature of Kubernetes that allow you to mark nodes with certain attributes or conditions, and then specify which pods can or cannot be scheduled on those nodes based on those attributes or conditions. Taints are applied to nodes, and tolerations are applied to pods.
