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: 

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

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 BindClientConfigFlags 

func BindClientConfigFlags(flags FlagSet, config *Config)

BindClientConfigFlags registers a standard set of CLI flags for connecting to a Kubernetes API server. TODO this method is superceded by pkg/client/clientcmd/client_builder.go

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)

DefaultServerURL converts a host, host:port, or URL string to the default base server API path to use with a Client at a given API version following the standard conventions for a Kubernetes API.

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 TransportFor 

func TransportFor(config *Config) (http.RoundTripper, error)

TransportFor returns an http.RoundTripper that will provide the authentication or transport level security defined by the provided Config. Will return the default http.DefaultTransport if no special case behavior is needed.

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

func NewRESTClient 

func NewRESTClient(baseURL *url.URL, apiVersion string, c runtime.Codec, legacyBehavior bool) *RESTClient

NewRESTClient creates a new RESTClient. This client performs generic REST functions such as Get, Put, Post, and Delete on specified paths. Codec controls encoding and decoding of responses from the server. If this client should use the older, legacy API conventions from Kubernetes API v1beta1 and v1beta2, set legacyBehavior true.

func RESTClientFor 

func RESTClientFor(config *Config) (*RESTClient, error)

RESTClientFor returns a RESTClient that satisfies the requested attributes on a client Config object. Note that a RESTClient may require fields that are optional when initializing a Client. A RESTClient created by this method is generic - it expects to operate on an API that follows the Kubernetes conventions, but may not be the Kubernetes API.

func (*RESTClient) Post 

func (c *RESTClient) Post() *Request

func (*Request) Do 

func (r *Request) Do() Result
