Types ¶

type VerifyNode ¶

type VerifyNode struct {
	ClientConfig *rest.Config
	K8s          *clientgo.Clientset
	Logger       logr.Logger
	Region       string

	NodeIPAddress string
}

VerifyNode checks that a node is healthy, can run pods, extract logs and run commands on them.

func (VerifyNode) Run ¶
