Types

type APIVersions

type APIVersions struct {
	TypeMeta `json:",inline"`
	// versions are the api versions that are available.
	Versions []string `json:"versions"`
	// a map of client CIDR to server address that is serving this group.
	// This is to help clients reach servers in the most network-efficient way possible.
	// Clients can use the appropriate server address as per the CIDR that they match.
	// In case of multiple matches, clients should use the longest matching CIDR.
	// The server returns only those CIDRs that it thinks that the client can match.
	// For example: the master will return an internal IP CIDR only, if the client reaches the server using an internal IP.
	// Server looks at X-Forwarded-For header or X-Real-Ip header or request.RemoteAddr (in that order) to get the client IP.
	ServerAddressByClientCIDRs []ServerAddressByClientCIDR `json:"serverAddressByClientCIDRs"`
}

APIVersions lists the versions that are available, to allow clients to discover the API at /api, which is the root path of the legacy v1 API.

type CauseType

type CauseType string

CauseType is a machine readable value providing more detail about what occurred in a status response. An operation may have multiple causes for a status (whether Failure or Success).

type Client

type Client interface {
	Versions() (APIVersions, error)
	// Scales returns an interface for interactive with Scale resources.
	// If namespace is empty the default client namespace will be used.
	Scales(namespace string) ScalesInterface
	Update(c Config) error
}

func New

func New(c Config) (Client, error)

type Config

type Config struct {
	URLs      []string
	Namespace string
	Token     string
	TLSConfig *tls.Config
}

func NewConfigInCluster

func NewConfigInCluster() (Config, error)

type JSONPatch

type JSONPatch struct {
	Operation string      `json:"op"`
	Path      string      `json:"path"`
	Value     interface{} `json:"value"`
}

represents a patch operation on a JSON object.

type ListMeta

type ListMeta struct {
	// SelfLink is a URL representing this object.
	// Populated by the system.
	// Read-only.
	SelfLink string `json:"selfLink,omitempty"`

	// String that identifies the server's internal version of this object that
	// can be used by clients to determine when objects have changed.
	// Value must be treated as opaque by clients and passed unmodified back to the server.
	// Populated by the system.
	// Read-only.
	// More info: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#concurrency-control-and-consistency
	ResourceVersion string `json:"resourceVersion,omitempty"`
}

ListMeta describes metadata that synthetic resources must have, including lists and various status objects. A resource may have only one of {ObjectMeta, ListMeta}.

type ObjectMeta

type ObjectMeta struct {
	// Name is unique within a namespace.  Name is required when creating resources, although
	// some resources may allow a client to request the generation of an appropriate name
	// automatically. Name is primarily intended for creation idempotence and configuration
	// definition.
	Name string `json:"name,omitempty"`

	// GenerateName indicates that the name should be made unique by the server prior to persisting
	// it. A non-empty value for the field indicates the name will be made unique (and the name
	// returned to the client will be different than the name passed). The value of this field will
	// be combined with a unique suffix on the server if the Name field has not been provided.
	// The provided value must be valid within the rules for Name, and may be truncated by the length
	// of the suffix required to make the value unique on the server.
	//
	// If this field is specified, and Name is not present, the server will NOT return a 409 if the
	// generated name exists - instead, it will either return 201 Created or 500 with Reason
	// ServerTimeout indicating a unique name could not be found in the time allotted, and the client
	// should retry (optionally after the time indicated in the Retry-After header).
	GenerateName string `json:"generateName,omitempty"`

	// Namespace defines the space within which name must be unique. An empty namespace is
	// equivalent to the "default" namespace, but "default" is the canonical representation.
	// Not all objects are required to be scoped to a namespace - the value of this field for
	// those objects will be empty.
	Namespace string `json:"namespace,omitempty"`

	// SelfLink is a URL representing this object.
	SelfLink string `json:"selfLink,omitempty"`

	// UID is the unique in time and space value for this object. It is typically generated by
	// the server on successful creation of a resource and is not allowed to change on PUT
	// operations.
	UID string `json:"uid,omitempty"`

	// An opaque value that represents the version of this resource. May be used for optimistic
	// concurrency, change detection, and the watch operation on a resource or set of resources.
	// Clients must treat these values as opaque and values may only be valid for a particular
	// resource or set of resources. Only servers will generate resource versions.
	ResourceVersion string `json:"resourceVersion,omitempty"`

	// A sequence number representing a specific generation of the desired state.
	// Populated by the system. Read-only.
	Generation int64 `json:"generation,omitempty"`

	// CreationTimestamp is a timestamp representing the server time when this object was
	// created. It is not guaranteed to be set in happens-before order across separate operations.
	// Clients may not set this value. It is represented in RFC3339 form and is in UTC.
	CreationTimestamp string `json:"creationTimestamp,omitempty"`

	// DeletionTimestamp is the time after which this resource will be deleted. This
	// field is set by the server when a graceful deletion is requested by the user, and is not
	// directly settable by a client. The resource will be deleted (no longer visible from
	// resource lists, and not reachable by name) after the time in this field. Once set, this
	// value may not be unset or be set further into the future, although it may be shortened
	// or the resource may be deleted prior to this time. For example, a user may request that
	// a pod is deleted in 30 seconds. The Kubelet will react by sending a graceful termination
	// signal to the containers in the pod. Once the resource is deleted in the API, the Kubelet
	// will send a hard termination signal to the container.
	DeletionTimestamp string `json:"deletionTimestamp,omitempty"`

	// DeletionGracePeriodSeconds records the graceful deletion value set when graceful deletion
	// was requested. Represents the most recent grace period, and may only be shortened once set.
	DeletionGracePeriodSeconds *int64 `json:"deletionGracePeriodSeconds,omitempty"`

	// Labels are key value pairs that may be used to scope and select individual resources.
	// Label keys are of the form:
	//     label-key ::= prefixed-name | name
	//     prefixed-name ::= prefix '/' name
	//     prefix ::= DNS_SUBDOMAIN
	//     name ::= DNS_LABEL
	// The prefix is optional.  If the prefix is not specified, the key is assumed to be private
	// to the user.  Other system components that wish to use labels must specify a prefix.  The
	// "kubernetes.io/" prefix is reserved for use by kubernetes components.
	Labels map[string]string `json:"labels,omitempty"`

	// Annotations are unstructured key value data stored with a resource that may be set by
	// external tooling. They are not queryable and should be preserved when modifying
	// objects.  Annotation keys have the same formatting restrictions as Label keys. See the
	// comments on Labels for details.
	Annotations map[string]string `json:"annotations,omitempty"`

	// List of objects depended by this object. If ALL objects in the list have
	// been deleted, this object will be garbage collected. If this object is managed by a controller,
	// then an entry in this list will point to this controller, with the controller field set to true.
	// There cannot be more than one managing controller.
	OwnerReferences []OwnerReference `json:"ownerReferences,omitempty"`

	// Must be empty before the object is deleted from the registry. Each entry
	// is an identifier for the responsible component that will remove the entry
	// from the list. If the deletionTimestamp of the object is non-nil, entries
	// in this list can only be removed.
	Finalizers []string `json:"finalizers,omitempty"`

	// The name of the cluster which the object belongs to.
	// This is used to distinguish resources with same name and namespace in different clusters.
	// This field is not set anywhere right now and apiserver is going to ignore it if set in create or update request.
	ClusterName string `json:"clusterName,omitempty"`
}

ObjectMeta is metadata that all persisted resources must have, which includes all objects users must create.

type OwnerReference

type OwnerReference struct {
	// API version of the referent.
	APIVersion string `json:"apiVersion"`
	// Kind of the referent.
	// More info: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#types-kinds
	Kind string `json:"kind"`
	// Name of the referent.
	// More info: http://releases.k8s.io/HEAD/docs/user-guide/identifiers.md#names
	Name string `json:"name"`
	// UID of the referent.
	// More info: http://releases.k8s.io/HEAD/docs/user-guide/identifiers.md#uids
	UID string `json:"uid"`
	// If true, this reference points to the managing controller.
	Controller *bool `json:"controller,omitempty"`
}

OwnerReference contains enough information to let you identify an owning object. Currently, an owning object must be in the same namespace, so there is no namespace field.

type Scale

type Scale struct {
	TypeMeta `json:",inline"`
	// Standard object metadata; More info: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#metadata.
	ObjectMeta `json:"metadata,omitempty"`

	// defines the behavior of the scale. More info: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#spec-and-status.
	Spec ScaleSpec `json:"spec,omitempty"`

	// current status of the scale. More info: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#spec-and-status. Read-only.
	Status ScaleStatus `json:"status,omitempty"`
}

represents a scaling request for a resource.

type ScaleSpec

type ScaleSpec struct {
	// desired number of instances for the scaled object.
	Replicas int32 `json:"replicas,omitempty"`
}

describes the attributes of a scale subresource

type ScaleStatus

type ScaleStatus struct {
	// actual number of observed instances of the scaled object.
	Replicas int32 `json:"replicas"`

	// label query over pods that should match the replicas count. More info: http://releases.k8s.io/HEAD/docs/user-guide/labels.md#label-selectors
	Selector map[string]string `json:"selector,omitempty"`

	// label selector for pods that should match the replicas count. This is a serializated
	// version of both map-based and more expressive set-based selectors. This is done to
	// avoid introspection in the clients. The string will be in the same format as the
	// query-param syntax. If the target type only supports map-based selectors, both this
	// field and map-based selector field are populated.
	// More info: http://releases.k8s.io/HEAD/docs/user-guide/labels.md#label-selectors
	TargetSelector string `json:"targetSelector,omitempty"`
}

represents the current status of a scale subresource.

type Scales

type Scales struct {
	// contains filtered or unexported fields
}

func (Scales) Get

func (s Scales) Get(kind, name string) (*Scale, error)

func (Scales) Update

func (s Scales) Update(kind string, scale *Scale) error

type ScalesInterface

type ScalesInterface interface {
	Get(kind, name string) (*Scale, error)
	Update(kind string, scale *Scale) error
}

type ServerAddressByClientCIDR

type ServerAddressByClientCIDR struct {
	// The CIDR with which clients can match their IP to figure out the server address that they should use.
	ClientCIDR string `json:"clientCIDR"`
	// Address of this server, suitable for a client that matches the above CIDR.
	// This can be a hostname, hostname:port, IP or IP:port.
	ServerAddress string `json:"serverAddress"`
}

ServerAddressByClientCIDR helps the client to determine the server address that they should use, depending on the clientCIDR that they match.

type Status

type Status struct {
	TypeMeta `json:",inline"`
	// Standard list metadata.
	// More info: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#types-kinds
	ListMeta `json:"metadata,omitempty"`

	// Status of the operation.
	// One of: "Success" or "Failure".
	// More info: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#spec-and-status
	Status string `json:"status,omitempty"`
	// A human-readable description of the status of this operation.
	Message string `json:"message,omitempty"`
	// A machine-readable description of why this operation is in the
	// "Failure" status. If this value is empty there
	// is no information available. A Reason clarifies an HTTP status
	// code but does not override it.
	Reason StatusReason `json:"reason,omitempty"`
	// Extended data associated with the reason.  Each reason may define its
	// own extended details. This field is optional and the data returned
	// is not guaranteed to conform to any schema except that defined by
	// the reason type.
	Details *StatusDetails `json:"details,omitempty"`
	// Suggested HTTP return code for this status, 0 if not set.
	Code int32 `json:"code,omitempty"`
}

Status is a return value for calls that don't return other objects.

func (Status) Error

func (s Status) Error() string

type StatusCause

type StatusCause struct {
	// A machine-readable description of the cause of the error. If this value is
	// empty there is no information available.
	Type CauseType `json:"reason,omitempty"`
	// A human-readable description of the cause of the error.  This field may be
	// presented as-is to a reader.
	Message string `json:"message,omitempty"`
	// The field of the resource that has caused this error, as named by its JSON
	// serialization. May include dot and postfix notation for nested attributes.
	// Arrays are zero-indexed.  Fields may appear more than once in an array of
	// causes due to fields having multiple errors.
	// Optional.
	//
	// Examples:
	//   "name" - the field "name" on the current resource
	//   "items[0].name" - the field "name" on the first array entry in "items"
	Field string `json:"field,omitempty"`
}

StatusCause provides more information about an api.Status failure, including cases when multiple errors are encountered.

type StatusDetails

type StatusDetails struct {
	// The name attribute of the resource associated with the status StatusReason
	// (when there is a single name which can be described).
	Name string `json:"name,omitempty"`
	// The group attribute of the resource associated with the status StatusReason.
	Group string `json:"group,omitempty"`
	// The kind attribute of the resource associated with the status StatusReason.
	// On some operations may differ from the requested resource Kind.
	// More info: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#types-kinds
	Kind string `json:"kind,omitempty"`
	// The Causes array includes more details associated with the StatusReason
	// failure. Not all StatusReasons may provide detailed causes.
	Causes []StatusCause `json:"causes,omitempty"`
	// If specified, the time in seconds before the operation should be retried.
	RetryAfterSeconds int32 `json:"retryAfterSeconds,omitempty"`
}

StatusDetails is a set of additional properties that MAY be set by the server to provide additional information about a response. The Reason field of a Status object defines what attributes will be set. Clients must ignore fields that do not match the defined type of each attribute, and should assume that any attribute may be empty, invalid, or under defined.

type StatusReason

type StatusReason string

StatusReason is an enumeration of possible failure causes. Each StatusReason must map to a single HTTP status code, but multiple reasons may map to the same HTTP status code.

type TypeMeta

type TypeMeta struct {
	// Kind is a string value representing the REST resource this object represents.
	// Servers may infer this from the endpoint the client submits requests to.
	// Cannot be updated.
	// In CamelCase.
	// More info: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#types-kinds
	Kind string `json:"kind,omitempty"`

	// 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.
	// More info: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#resources
	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.
