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 TODO this method is superceded by pkg/client/clientcmd/client_builder.go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 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 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

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. Handles polling the server in the event a continuation was sent.

  • If the server responds with a status: *errors.StatusError or *errors.UnexpectedObjectError
