Types

type Cluster

type Cluster struct {
	// List of master nodes.
	Masters []*v1.Node
	// List of worker nodes.
	Workers []*v1.Node
	// MaxDisruption defines the max no. of nodes that will be rebooted in parallel.
	// Accepts int eg. '3' for no. of nodes, and string '30%' for percent.
	// Defaults to 100%.
	MaxDisruption intstr.IntOrString
	// contains filtered or unexported fields
}
