type NodeNumber ¶

type NodeNumber struct {
	// contains filtered or unexported fields
}

NodeNumber is a plugin that favors nodes that has the same number suffix as number suffix of pod name. And it will delay the binding of pod by {node suffix number} seconds. For example: When schedule a pod named Pod1, a Node named Node9 gets a higher score than a node named Node1. And if it is decided that Pod1 will go to Node9, this plugin delay the binding by 9 seconds.

IMPORTANT NOTE: this plugin only handle single digit numbers only.
