Overview

Package api contains the latest (or "internal") version of the Kubernetes API objects. This is the API objects as represented in memory. The contract presented to clients is located in the versioned packages, which are sub-directories. The first one is "v1beta1". Those packages describe how a particular version is serialized to storage/network.

const (
	// NamespaceDefault means the object is in the default namespace which is applied when not specified by clients
	NamespaceDefault string = "default"
	// NamespaceAll is the default argument to specify on a context when you want to list or filter resources across all namespaces
	NamespaceAll string = ""

View Source 
var ErrNilObject = errors.New("Can't reference a nil object")

ErrNilObject indicates an error that the obj passed to GetReference is nil.

	//                   field attributes will be set.
	// Status code 422
	StatusReasonInvalid StatusReason = "Invalid"

	// StatusReasonBadRequest means that the request itself was invalid, because the request
	// doesn't make any sense, for example deleting a read-only object.  This is different than
	// StatusReasonInvalid above which indicates that the API call could possibly succeed, but the
	// data was invalid.  API calls that return BadRequest can never succeed.
	StatusReasonBadRequest StatusReason = "BadRequest"

	// StatusReasonInternalError indicates that an internal error occurred, it is unexpected
	// and the outcome of the call is unknown.

	// Servers should convert recognized schemas to the latest internal value, and
	// may reject unrecognized values.
	APIVersion string `json:"apiVersion,omitempty" yaml:"apiVersion,omitempty"`
}

TypeMeta describes an individual object in an API response or request with strings representing the type of the object and its API schema version. Structures that are versioned or persisted should inline TypeMeta.

	// a unique name.
	Name string `json:"name" yaml:"name"`

	// things that are allowed to see the host machine. Most containers will NOT need this.
	// TODO(jonesdl) We need to restrict who can use host directory mounts and who can/can not
	// mount host directories as read/write.
