Functions

This section is empty.

Types

type APIObject

type APIObject struct {
	Object interface{}
}

APIObject has appropriate encoder and decoder functions, such that on the wire, it's stored as a []byte, but in memory, the contained object is accessable as an interface{} via the Get() function. Only objects having a JSONBase may be stored via APIObject. The purpose of this is to allow an API object of type known only at runtime to be embedded within other API objects.

type Binding

type Binding struct {
	JSONBase `json:",inline" yaml:",inline"`
	PodID    string `json:"podID" yaml:"podID"`
	Host     string `json:"host" yaml:"host"`
}

Binding is written by a scheduler to cause a pod to be bound to a host.

type CauseType

type CauseType string

CauseType is a machine readable value providing more detail about what occured in a status response. An operation may have multiple causes for a status (whether failure, success, or working).

const (
	// CauseTypeFieldValueNotFound is used to report failure to find a requested value
	// (e.g. looking up an ID).
	CauseTypeFieldValueNotFound CauseType = "fieldValueNotFound"
	// CauseTypeFieldValueInvalid is used to report required values that are not
	// provided (e.g. empty strings, null values, or empty arrays).
	CauseTypeFieldValueRequired CauseType = "fieldValueRequired"
	// CauseTypeFieldValueDuplicate is used to report collisions of values that must be
	// unique (e.g. unique IDs).
	CauseTypeFieldValueDuplicate CauseType = "fieldValueDuplicate"
	// CauseTypeFieldValueInvalid is used to report malformed values (e.g. failed regex
	// match).
	CauseTypeFieldValueInvalid CauseType = "fieldValueInvalid"
	// CauseTypeFieldValueNotSupported is used to report valid (as per formatting rules)
	// values that can not be handled (e.g. an enumerated string).

	// TODO(jonesdl) We need to restrict who can use host directory mounts and
	// who can/can not mount host directories as read/write.
