Summary
Tolerations allow the scheduler to schedule pods with matching taints. Tolerations allow scheduling but don't guarantee scheduling: the scheduler also evaluates other parameters as part of its function.
Taints and tolerations work together to ensure that pods are not scheduled onto inappropriate nodes.

Summary
Taints and tolerations are a mechanism that allows you to ensure that pods are not placed on inappropriate nodes. Taints are added to nodes, while tolerations are defined in the pod specification. When you taint a node, it will repel all the pods except those that have a toleration for that taint.

Summary
Taints and tolerations are used in Kubernetes clusters to prevent pods from scheduling on master nodes, prevent crashing under high loads, and schedule pods on nodes with taints. Taints can be added to nodes with the command kubectl taint nodes, and tolerations are applied to pods' manifests in the format - key, operator, value, effect, and tolerationSeconds. K8s Metrics, Logging, and Tracing provides pre-built dashboards to monitor the health of the cluster and troubleshoot issues faster.
