	plans ...Plan,
) Service

NewService initialized and returns a new Service

func NewServiceFromJSON

NewServiceFromJSON returns a new Service unmarshalled from the provided JSON []byte

type ServiceManager added in v0.10.0 

type ServiceManager interface {
	// GetEmptyInstanceDetails returns an "empty" service-specific object that
	// can be populated with data during unmarshaling of JSON to an Instance
	GetEmptyInstanceDetails() InstanceDetails
	// GetProvisioner returns a provisioner that defines the steps a module must
	// execute asynchronously to provision a service.
	GetProvisioner(Plan) (Provisioner, error)
	// ValidateUpdatingParameters validates the provided
	// updating parameters against against current instance state
	// and returns an error if there is any problem
	ValidateUpdatingParameters(Instance) error
	// GetUpdater returns a updater that defines the steps a module must
	// execute asynchronously to update a service.
	GetUpdater(Plan) (Updater, error)
	// GetEmptyBindingDetails returns an "empty" service-specific object that
	// can be populated with data during unmarshaling of JSON to a Binding
	GetEmptyBindingDetails() BindingDetails
	// Bind synchronously binds to a service
	Bind(Instance, BindingParameters) (BindingDetails, error)
	// GetCredentials returns service-specific credentials populated from instance
	// and binding details
	GetCredentials(Instance, Binding) (Credentials, error)
	// Unbind synchronously unbinds from a service
	Unbind(Instance, Binding) error
	// GetDeprovisioner returns a deprovisioner that defines the steps a module
	// must execute asynchronously to deprovision a service
	GetDeprovisioner(Plan) (Deprovisioner, error)
}

ServiceManager is an interface to be implemented by module components responsible for managing the lifecycle of services and plans thereof

type ServicePlanMetadata struct {
	DisplayName string   `json:"displayName,omitempty"`
	Bullets     []string `json:"bullets,omitempty"`
}

type ServiceProperties 

type ServiceProperties struct {
	Name          string           `json:"name"`
	ID            string           `json:"id"`
	Description   string           `json:"description"`
	Metadata      *ServiceMetadata `json:"metadata,omitempty"`
	Tags          []string         `json:"tags"`
	Bindable      bool             `json:"bindable"`
	PlanUpdatable bool             `json:"plan_updateable"` // Misspelling is
	// deliberate to match the spec
	ParentServiceID string                 `json:"-"`
	ChildServiceID  string                 `json:"-"`
	Extended        map[string]interface{} `json:"-"`
	EndOfLife       bool                   `json:"-"`
}

ServiceProperties represent the properties of a Service that can be directly instantiated and passed to the NewService() constructor function which will carry out all necessary initialization.

type Stability 

type Stability int

Stability is a type that represents the relative stability of a service module 

const (
	// StabilityExperimental represents relative stability of the most immature
	// service modules. At this level of stability, we're not even certain we've
	// built the right thing!
	StabilityExperimental Stability = iota
	// StabilityPreview represents relative stability of modules we believe are
	// approaching a stable state.
	StabilityPreview
	// StabilityStable represents relative stability of the mature, production-
	// ready service modules.
	StabilityStable
)

type StringPropertySchema added in v0.12.0 

type StringPropertySchema struct {
	Description             string                        `json:"description,omitempty"` // nolint: lll
	MinLength               *int                          `json:"minLength,omitempty"`   // nolint: lll
	MaxLength               *int                          `json:"maxLength,omitempty"`   // nolint: lll
	AllowedValues           []string                      `json:"enum,omitempty"`
	AllowedPattern          *regexp.Regexp                `json:"pattern,omitempty"` // nolint: lll
	CustomPropertyValidator CustomStringPropertyValidator `json:"-"`
	DefaultValue            string                        `json:"default,omitempty"` // nolint: lll
}

StringPropertySchema represents schema for a single string property

func (StringPropertySchema) MarshalJSON added in v0.12.0 

func (s StringPropertySchema) MarshalJSON() ([]byte, error)

MarshalJSON provides functionality to marshal a StringPropertySchema to JSON

type Updater 

type Updater interface {
	GetFirstStepName() (string, bool)
	GetStep(name string) (UpdatingStep, bool)
	GetNextStepName(name string) (string, bool)
}

Updater is an interface to be implemented by types that model a declared chain of tasks used to asynchronously update a service

func NewUpdater 

func NewUpdater(steps ...UpdatingStep) (Updater, error)

NewUpdater returns a new updater

type UpdatingStep 

type UpdatingStep interface {
	GetName() string
	Execute(
		ctx context.Context,
		instance Instance,
	) (InstanceDetails, error)
}

UpdatingStep is an interface to be implemented by types that represent a single step in a chain of steps that defines a updating process

func NewUpdatingStep 

func NewUpdatingStep(
	name string,
	fn UpdatingStepFunction,
) UpdatingStep

NewUpdatingStep returns a new UpdatingStep

type UpdatingStepFunction 

type UpdatingStepFunction func(
	ctx context.Context,
	instance Instance,
) (InstanceDetails, error)

UpdatingStepFunction is the signature for functions that implement a updating step

type ValidationError 

type ValidationError struct {
	Field string
	Issue string
}

ValidationError represents an error validating requestParameters. This specific error type should be used to allow the broker's framework to differentiate between validation errors and other common, unexpected errors.

func NewValidationError 

func NewValidationError(field, issue string) *ValidationError

NewValidationError returns a new ValidationError for the given field and issue

func (*ValidationError) Error 

func (e *ValidationError) Error() string
