This is a "preference" or "soft" version of NoSchedule -- the system will try to avoid placing a Threat and fraud protection for your web applications and APIs. For example, if you have an application with a lot of local state, you might want to keep the pods bound to node for a longer time in the event of network partition, allowing for the partition to recover and avoiding pod eviction. admission controller. When a node experiences one of these conditions, OpenShift Container Platform automatically adds taints to the node, and starts evicting and rescheduling the pods on different nodes. You apply taints to a node through the Node specification (NodeSpec) and apply tolerations to a pod through the Pod specification (PodSpec). OpenShift Container Platform processes multiple taints and tolerations as follows: Process the taints for which the pod has a matching toleration. If you want to dedicate a set of nodes for exclusive use by a particular set of users, add a toleration to their pods.
