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 = ""
	// NamespaceNone is the argument for a context when there is no namespace.
	NamespaceNone string = ""

var Codec = runtime.CodecFor(Scheme, "")

Codec is the identity codec for this package - it can only convert itself to itself.

View Source
var ForTesting_ReferencesAllowBlankSelfLinks = false

ForTesting_ReferencesAllowBlankSelfLinks can be set to true in tests to avoid "ErrNoSelfLink" errors.

	// reference is to a container within a pod, this would take on a value like:
	// "spec.containers{name}" (where "name" refers to the name of the container that triggered
	// the event) or if no container name is specified "spec.containers[2]" (container with
