Types

type Client

type Client struct {
	GRFn func(from, to *deployapi.DeploymentConfig, spec *deployapi.DeploymentConfigRollbackSpec) (*deployapi.DeploymentConfig, error)
	RCFn func(ctx kapi.Context, name string) (*kapi.ReplicationController, error)
	DCFn func(ctx kapi.Context, name string) (*deployapi.DeploymentConfig, error)
}

Client provides an implementation of Generator client

func (Client) GenerateRollback

func (c Client) GenerateRollback(from, to *deployapi.DeploymentConfig, spec *deployapi.DeploymentConfigRollbackSpec) (*deployapi.DeploymentConfig, error)

GenerateRollback generates a new deploymentConfig by merging a pair of deploymentConfigs

func (Client) GetDeployment

func (c Client) GetDeployment(ctx kapi.Context, name string) (*kapi.ReplicationController, error)

GetDeployment returns the deployment with the provided context and name

func (Client) GetDeploymentConfig

func (c Client) GetDeploymentConfig(ctx kapi.Context, name string) (*deployapi.DeploymentConfig, error)

GetDeployment returns the deploymentConfig with the provided context and name

type DeprecatedREST

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

REST provides a rollback generation endpoint. Only the Create method is implemented.

func NewDeprecatedREST

func NewDeprecatedREST(generator GeneratorClient, codec runtime.Codec) *DeprecatedREST

NewDeprecatedREST safely creates a new REST.

func (*DeprecatedREST) Create

func (s *DeprecatedREST) Create(ctx kapi.Context, obj runtime.Object) (runtime.Object, error)

Create generates a new DeploymentConfig representing a rollback.

func (*DeprecatedREST) New

func (s *DeprecatedREST) New() runtime.Object

New creates an empty DeploymentConfigRollback resource

type GeneratorClient

type GeneratorClient interface {
	GenerateRollback(from, to *deployapi.DeploymentConfig, spec *deployapi.DeploymentConfigRollbackSpec) (*deployapi.DeploymentConfig, error)
	GetDeployment(ctx kapi.Context, name string) (*kapi.ReplicationController, error)
	GetDeploymentConfig(ctx kapi.Context, name string) (*deployapi.DeploymentConfig, error)
}

GeneratorClient defines a local interface to a rollback generator for testability.

type REST

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

REST provides a rollback generation endpoint. Only the Create method is implemented.

func NewREST

func NewREST(oc client.Interface, kc kclient.Interface, codec runtime.Codec) *REST

NewREST safely creates a new REST.

func (*REST) Create

func (r *REST) Create(ctx kapi.Context, obj runtime.Object) (runtime.Object, error)

Create generates a new DeploymentConfig representing a rollback.

func (*REST) New

func (r *REST) New() runtime.Object

New creates an empty DeploymentConfigRollback resource

type RollbackGenerator

type RollbackGenerator interface {
	// GenerateRollback creates a new deployment config by merging to onto from
	// based on the options provided by spec. The latestVersion of the result is
	// unconditionally incremented, as rollback candidates should be possible
	// to be deployed manually regardless of other system behavior such as
	// triggering.
	//
	// Any image change triggers on the new config are disabled to prevent
	// triggered deployments from immediately replacing the rollback.
	GenerateRollback(from, to *deployapi.DeploymentConfig, spec *deployapi.DeploymentConfigRollbackSpec) (*deployapi.DeploymentConfig, error)
}

RollbackGenerator generates a new deployment config by merging a pair of deployment configs in a configurable way.

func NewRollbackGenerator

func NewRollbackGenerator() RollbackGenerator

NewRollbackGenerator returns a new rollback generator.
