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

View Source 
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

View Source 
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!

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")
)
View Source 
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.

View Source 
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
	},
	func(a, b util.Time) bool {
		return a.UTC() == b.UTC()
	},
)

Semantic can do semantic deep equality checks for api objects. Example: api.Semantic.DeepEqual(aPod, aPodWithNonNilButEmptyMaps) == true

	// to take any further action.  It is the result of the server being configured to deny access for some reason
	// to the requested resource by the client.
	// Details (optional):
	//   "kind" string - the kind attribute of the forbidden resource
	//                   on some operations may differ from the requested

	StatusReasonConflict StatusReason = "Conflict"

	// StatusReasonInvalid means the requested create or update operation cannot be
	// completed due to invalid data provided as part of the request. The client may
	// need to alter the request. When set, the client may use the StatusDetails
	// message field as a summary of the issues encountered.
	// Details (optional):
	//   "kind" string - the kind attribute of the invalid resource
	//   "id"   string - the identifier of the invalid resource

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

	// StatusReasonServerTimeout means the server can be reached and understood the request,
	// but cannot complete the action in a reasonable time. The client should retry the request.
	// This is may be due to temporary server load or a transient communication issue with
	// another server. Status code 500 is used because the HTTP spec provides no suitable
	// server-requested client retry and the 5xx class represents actionable errors.
	// Details (optional):
	//   "kind" string - the kind attribute of the resource being acted on.
	//   "id"   string - the operation that is being attempted.
	// Status code 500
	StatusReasonServerTimeout StatusReason = "ServerTimeout"

	// StatusReasonTimeout means that the request could not be completed within the given time.
	// Clients can get this response only when they specified a timeout param in the request.
	// The request might succeed with an increased value of timeout param.
	// Status code 504
	StatusReasonTimeout StatusReason = "Timeout"

	// 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"

	// StatusReasonMethodNotAllowed means that the action the client attempted to perform on the
	// resource was not supported by the code - for instance, attempting to delete a resource that
	// can only be created. API calls that return MethodNotAllowed can never succeed.
	StatusReasonMethodNotAllowed StatusReason = "MethodNotAllowed"

	// StatusReasonInternalError indicates that an internal error occurred, it is unexpected
	// and the outcome of the call is unknown.
	// Details (optional):
	//   "causes" - The original error
	// Status code 500
	StatusReasonInternalError = "InternalError"
)

	// APIVersion defines the versioned schema of this representation of an object.
	// Servers should convert recognized schemas to the latest internal value, and
	// may reject unrecognized values.
	APIVersion string `json:"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.

	// Required: This must be a DNS_LABEL.  Each volume in a pod must have
	// a unique name.
	Name string `json:"name"`

}

VolumeMount describes a mounting of a Volume within a container.

type VolumeSource 

type VolumeSource struct {
	// HostPath represents file or directory on the host machine that is
	// directly exposed to the container. This is generally used for system
	// agents or other privileged 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.
	HostPath *HostPathVolumeSource `json:"hostPath"`
	// EmptyDir represents a temporary directory that shares a pod's lifetime.
	EmptyDir *EmptyDirVolumeSource `json:"emptyDir"`
