Constants

const AcceptorInterval = 1 * time.Second

AcceptorInterval is how often the UpdateAcceptor should check for readiness.

Types

type RecreateDeploymentStrategy

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

RecreateDeploymentStrategy is a simple strategy appropriate as a default. Its behavior is to scale down the last deployment to 0, and to scale up the new deployment to 1.

A failure to disable any existing deployments will be considered a deployment failure.

func NewRecreateDeploymentStrategy

func NewRecreateDeploymentStrategy(client kclient.Interface, tagClient client.ImageStreamTagsNamespacer, decoder runtime.Decoder, out, errOut io.Writer, until string) *RecreateDeploymentStrategy

NewRecreateDeploymentStrategy makes a RecreateDeploymentStrategy backed by a real HookExecutor and client.

func (*RecreateDeploymentStrategy) Deploy

func (s *RecreateDeploymentStrategy) Deploy(from *kapi.ReplicationController, to *kapi.ReplicationController, desiredReplicas int) error

Deploy makes deployment active and disables oldDeployments.

func (*RecreateDeploymentStrategy) DeployWithAcceptor

func (s *RecreateDeploymentStrategy) DeployWithAcceptor(from *kapi.ReplicationController, to *kapi.ReplicationController, desiredReplicas int, updateAcceptor strat.UpdateAcceptor) error

DeployWithAcceptor scales down from and then scales up to. If updateAcceptor is provided and the desired replica count is >1, the first replica of to is rolled out and validated before performing the full scale up.

This is currently only used in conjunction with the rolling update strategy for initial deployments.
