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 TODO this method is superceded by pkg/client/clientcmd/client_builder.go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 added in v0.5.1 

func BindKubeletClientConfigFlags(flags FlagSet, config *KubeletConfig)

func ControllerHasDesiredReplicas added in v0.9.0 

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 added in v0.12.0 

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 added in v0.10.0 

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 added in v0.5.1 

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 added in v0.8.0 

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

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.

NewRESTClient creates a new RESTClient. This client performs generic REST functions such as Get, Put, Post, and Delete on specified paths.

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 added in v0.5.1 

func NewRequest(client HTTPClient, verb string, baseURL *url.URL, apiVersion string,
	codec runtime.Codec, namespaceInQuery bool, preserveResourceCase bool) *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) Prefix added in v0.8.0 

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

func (*Request) RequestURI added in v0.12.0 

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

func (*Request) SetHeader added in v0.15.0 

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 added in v0.13.0 

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 added in v0.8.0 

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