	Cloud fi.Cloud

	// MasterInterval is the amount of time to wait after stopping a master instance
	MasterInterval time.Duration
	// NodeInterval is the amount of time to wait after stopping a non-master instance
	NodeInterval time.Duration
	// BastionInterval is the amount of time to wait after stopping a bastion instance
	BastionInterval time.Duration
	// Interactive prompts user to continue after each instance is updated

}

RollingUpdateCluster is a struct containing cluster information for a rolling update.

func (*RollingUpdateCluster) RollingUpdate

func (c *RollingUpdateCluster) RollingUpdate(groups map[string]*cloudinstances.CloudInstanceGroup, cluster *api.Cluster, instanceGroups *api.InstanceGroupList) error

RollingUpdate performs a rolling update on a K8s Cluster.

type RollingUpdateInstanceGroup

type RollingUpdateInstanceGroup struct {
	// Cloud is the kops cloud provider
	Cloud fi.Cloud
	// CloudGroup is the kops cloud provider groups
	CloudGroup *cloudinstances.CloudInstanceGroup
}

RollingUpdateInstanceGroup is the AWS ASG backing an InstanceGroup.

func NewRollingUpdateInstanceGroup

func NewRollingUpdateInstanceGroup(cloud fi.Cloud, cloudGroup *cloudinstances.CloudInstanceGroup) (*RollingUpdateInstanceGroup, error)

NewRollingUpdateInstanceGroup creates a new struct

func (*RollingUpdateInstanceGroup) Delete

func (r *RollingUpdateInstanceGroup) Delete() error

func (r *RollingUpdateInstanceGroup) RollingUpdate(rollingUpdateData *RollingUpdateCluster, cluster *api.Cluster, instanceGroupList *api.InstanceGroupList, isBastion bool, sleepAfterTerminate time.Duration, validationTimeout time.Duration) (err error)

RollingUpdate performs a rolling update on a list of ec2 instances.

func (*RollingUpdateInstanceGroup) ValidateCluster

func (r *RollingUpdateInstanceGroup) ValidateCluster(rollingUpdateData *RollingUpdateCluster, cluster *api.Cluster, instanceGroupList *api.InstanceGroupList) error

ValidateCluster runs our validation methods on the K8s Cluster.
