UpgradeAgentNode upgrades a Kubernetes 1.5 agent node to 1.6

func (*UpgradeAgentNode) CreateNode

func (kan *UpgradeAgentNode) CreateNode(ctx context.Context, poolName string, agentNo int) error

CreateNode creates a new master/agent node with the targeted version of Kubernetes

func (*UpgradeAgentNode) DeleteNode

func (kan *UpgradeAgentNode) DeleteNode(vmName *string, drain bool) error

DeleteNode takes state/resources of the master/agent node from ListNodeResources backs up/preserves state as needed by a specific version of Kubernetes and then deletes the node The 'drain' flag is used to invoke 'cordon and drain' flow.

func (*UpgradeAgentNode) Validate

func (kan *UpgradeAgentNode) Validate(vmName *string) error

Validate will verify that agent node has been upgraded as expected.
