Overview

Package client contains the implementation of the client side communication with the Kubernetes master. The Client class provides methods for reading, creating, updating, and deleting pods, replication controllers, services, and minions.

Most consumers should use the Config object to create a Client:

import (
  "k8s.io/kubernetes/pkg/client"
  "k8s.io/kubernetes/pkg/api"
  "k8s.io/kubernetes/pkg/fields"
  "k8s.io/kubernetes/pkg/labels"
)

[...]

config := &client.Config{
  Host:     "http://localhost:8080",
  Username: "test",
  Password: "password",
}
client, err := client.New(config)
if err != nil {
  // handle error
}
pods, err := client.Pods(api.NamespaceDefault).List(labels.Everything(), fields.Everything())
if err != nil {
  // handle error
}

More advanced consumers may wish to provide their own transport via a http.RoundTripper:

config := &client.Config{
  Host:      "https://localhost:8080",
  Transport: oauthclient.Transport(),
}
client, err := client.New(config)

The RESTClient type implements the Kubernetes API conventions (see `docs/api-conventions.md`) for a given API path and is intended for use by consumers implementing their own Kubernetes compatible APIs.

Functions

func BindKubeletClientConfigFlags

func BindKubeletClientConfigFlags(flags FlagSet, config *KubeletConfig)

func ControllerHasDesiredReplicas

func ControllerHasDesiredReplicas(c Interface, controller *api.ReplicationController) wait.ConditionFunc

ControllerHasDesiredReplicas returns a condition that will be true iff the desired replica count for a controller's ReplicaSelector equals the Replicas count.

func DefaultKubernetesUserAgent

func DefaultKubernetesUserAgent() string

DefaultKubernetesUserAgent returns the default user agent that clients can use.

func DefaultServerURL

func DefaultServerURL(host, prefix, version string, defaultTLS bool) (*url.URL, error)

func HTTPWrappersForConfig

func HTTPWrappersForConfig(config *Config, rt http.RoundTripper) (http.RoundTripper, error)

HTTPWrappersForConfig wraps a round tripper with any relevant layered behavior from the config. Exposed to allow more clients that need HTTP-like behavior but then must hijack the underlying connection (like WebSocket or HTTP2 clients). Pure HTTP clients should use the higher level TransportFor or RESTClientFor methods.

func IsConfigTransportTLS

func IsConfigTransportTLS(config Config) bool

IsConfigTransportTLS returns true iff the provided config will result in a protected connection to the server when it is passed to client.New() or client.RESTClientFor(). Use to determine when to send credentials over the wire.

Note: the Insecure flag is ignored when testing for this value, so MITM attacks are still possible.

func IsTimeout

func IsTimeout(err error) bool

IsTimeout tests if this is a timeout error in the underlying transport. This is unbelievably ugly. See: http://stackoverflow.com/questions/23494950/specifically-check-for-timeout-error for details

func LoadTLSFiles

func LoadTLSFiles(config *Config) error

LoadTLSFiles copies the data from the CertFile, KeyFile, and CAFile fields into the CertData, KeyData, and CAFile fields, or returns an error. If no error is returned, all three fields are either populated or were empty to start.

func MatchesServerVersion

func MatchesServerVersion(client *Client, c *Config) error

func NegotiateVersion

func NegotiateVersion(client *Client, c *Config, version string, clientRegisteredVersions []string) (string, error)

NegotiateVersion queries the server's supported api versions to find a version that both client and server support. - If no version is provided, try registered client versions in order of

preference.

- If version is provided, but not default config (explicitly requested via

commandline flag), and is unsupported by the server, print a warning to
stderr and try client's registered versions in order of preference.

- If version is config default, and the server does not support it,

return an error.

RESTClient imposes common Kubernetes API conventions on a set of resource paths. The baseURL is expected to point to an HTTP or HTTPS path that is the parent of one or more resources. The server should return a decodable API resource object, or an api.Status object which contains information about the reason for any failure.

Most consumers should use client.New() to get a Kubernetes API client.

type Request

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

Request allows for building up a request to a server in a chained fashion. Any errors are stored until the end of your call, so you only have to check once.

func NewRequest

func NewRequest(client HTTPClient, verb string, baseURL *url.URL, apiVersion string,
	codec runtime.Codec) *Request

NewRequest creates a new request helper object for accessing runtime.Objects on a server.

func (*Request) AbsPath

func (r *Request) AbsPath(segments ...string) *Request

AbsPath overwrites an existing path with the segments provided. Trailing slashes are preserved when a single segment is passed.

func (*Request) Body

func (r *Request) Body(obj interface{}) *Request

Body makes the request use obj as the body. Optional. If obj is a string, try to read a file of that name. If obj is a []byte, send it directly. If obj is an io.Reader, use it directly. If obj is a runtime.Object, marshal it correctly. Otherwise, set an error.

func (*Request) Do

func (r *Request) Do() Result

Do formats and executes the request. Returns a Result object for easy response processing.

Error type:

* If the request can't be constructed, or an error happened earlier while building its
  arguments: *RequestConstructionError
* If the server responds with a status: *errors.StatusError or *errors.UnexpectedObjectError
* http.Client.Do errors are returned directly.

func (*Request) DoRaw

func (r *Request) DoRaw() ([]byte, error)

func (*Request) Prefix

func (r *Request) Prefix(segments ...string) *Request

Prefix adds segments to the relative beginning to the request path. These items will be placed before the optional Namespace, Resource, or Name sections. Setting AbsPath will clear any previously set Prefix segments

func (*Request) RequestURI

func (r *Request) RequestURI(uri string) *Request

RequestURI overwrites existing path and parameters with the value of the provided server relative URI. Some parameters (those in specialParameters) cannot be overwritten.

func (*Request) Resource

func (r *Request) Resource(resource string) *Request

Resource sets the resource to access (<resource>/[ns/<namespace>/]<name>)

func (*Request) SetHeader

func (r *Request) SetHeader(key, value string) *Request

func (*Request) Stream

func (r *Request) Stream() (io.ReadCloser, error)

Stream formats and executes the request, and offers streaming of the response. Returns io.ReadCloser which could be used for streaming of the response, or an error Any non-2xx http status code causes an error. If we get a non-2xx code, we try to convert the body into an APIStatus object. If we can, we return that as an error. Otherwise, we create an error that lists the http status and the content of the response.

func (*Request) SubResource

func (r *Request) SubResource(subresources ...string) *Request

SubResource sets a sub-resource path which can be multiple segments segment after the resource name but before the suffix.

func (*Request) Suffix

func (r *Request) Suffix(segments ...string) *Request

Suffix appends segments to the end of the path. These items will be placed after the prefix and optional Namespace, Resource, or Name sections.

func (*Request) Timeout

func (r *Request) Timeout(d time.Duration) *Request

Timeout makes the request use the given duration as a timeout. Sets the "timeout" parameter.

func (*Request) URL

func (r *Request) URL() *url.URL

URL returns the current working URL.

func (*Request) UintParam

func (r *Request) UintParam(paramName string, u uint64) *Request

UintParam creates a query parameter with the given value.

func (*Request) UnversionedPath

func (r *Request) UnversionedPath(segments ...string) *Request

UnversionedPath strips the apiVersion from the baseURL before appending segments.

func (*Request) Upgrade

func (r *Request) Upgrade(config *Config, newRoundTripperFunc func(*tls.Config) httpstream.UpgradeRoundTripper) (httpstream.Connection, error)

Upgrade upgrades the request so that it supports multiplexed bidirectional streams. The current implementation uses SPDY, but this could be replaced with HTTP/2 once it's available, or something else.

func (*Request) Watch

func (r *Request) Watch() (watch.Interface, error)

Watch attempts to begin watching the requested location. Returns a watch.Interface, or an error.
