What is TaintManagerEviction

The log line you provided, "Normal TaintManagerEviction pod/podname Marking for deletion Pod namespace/podname", indicates that the Kubernetes Taint Manager has marked a pod for deletion. This typically occurs when a node is being evicted, either due to resource constraints, node maintenance, or other reasons.

Here's a breakdown of the components of the log line:

Normal: Indicates that this is a normal event, not an error or warning.

TaintManagerEviction: Refers to the reason for the pod eviction, which in this case is likely related to taints and tolerations configured on the node.

pod/podname: Specifies the name of the pod that is being marked for deletion.

Pod namespace/podname: Specifies the namespace and name of the pod being marked for deletion
