What is label in Kubernetes?
Labels are key/value pairs that are attached to objects, such as pods.

Labels can be used to organize and to select subsets of objects.
What is taints and Tolerations in Kubernetes?
Node affinity is a property of Pods that attracts them to a set of nodes (either as a preference or a hard requirement). Taints are the opposite — they allow a node to repel a set of pods. Tolerations are applied to pods. Tolerations allow the scheduler to schedule pods with matching taints.
