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.

Constants ¶
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 = "" // TerminationMessagePathDefault means the default path to capture the application termination message running in a container TerminationMessagePathDefault string = "/dev/termination-log" )
const ( StatusSuccess = "Success" StatusFailure = "Failure" )
Values of Status.Status
const ( // Enable stdin for remote command execution ExecStdinParam = "input" // Enable stdout for remote command execution ExecStdoutParam = "output" // Enable stderr for remote command execution ExecStderrParam = "error" // Enable TTY for remote command execution ExecTTYParam = "tty" // Command to run for remote command execution ExecCommandParamm = "command" StreamType = "streamType" StreamTypeStdin = "stdin" StreamTypeStdout = "stdout" StreamTypeStderr = "stderr" StreamTypeData = "data" StreamTypeError = "error" PortHeader = "port" )
These constants are for remote command execution and port forwarding and are used by both the client side and server side components.
This is probably not the ideal place for them, but it didn't seem worth it to create pkg/exec and pkg/portforward just to contain a single file with constants in it. Suggestions for more appropriate alternatives are definitely welcome!
const MaxSecretSize = 1 * 1024 * 1024
Variables ¶
var ( // Errors that could be returned by GetReference. ErrNilObject = errors.New("can't reference a nil object") ErrNoSelfLink = errors.New("selfLink was empty, can't make reference") )
var Codec = runtime.CodecFor(Scheme, "")
Codec is the identity codec for this package - it can only convert itself to itself.
var ForTesting_ReferencesAllowBlankSelfLinks = false
ForTesting_ReferencesAllowBlankSelfLinks can be set to true in tests to avoid "ErrNoSelfLink" errors.
var Scheme = runtime.NewScheme()
Scheme is the default instance of runtime.Scheme to which types in the Kubernetes API are already registered.
var Semantic = conversion.EqualitiesOrDie( func(a, b resource.Quantity) bool { if a.Amount == nil && b.MilliValue() == 0 { return true } if b.Amount == nil && a.MilliValue() == 0 { return true } if a.Amount == nil || b.Amount == nil { return false } return a.Amount.Cmp(b.Amount) == 0 }, )
Semantic can do semantic deep equality checks for api objects. Example: api.Semantic.DeepEqual(aPod, aPodWithNonNilButEmptyMaps) == true
Functions ¶

func GenerateName ¶ added in v0.10.0
func GenerateName(u NameGenerator, meta *ObjectMeta)
GenerateName will resolve the object name of the provided ObjectMeta to a generated version if necessary. It expects that validation for ObjectMeta has already completed (that Base is a valid name) and that the NameGenerator generates a name that is also valid.
func HasObjectMetaSystemFieldValues ¶ added in v0.5.1

EmptyDir *EmptyDirVolumeSource `json:"emptyDir"` // GCEPersistentDisk represents a GCE Disk resource that is attached to a // kubelet's host machine and then exposed to the pod.
