Documentation

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 TODO this method is superceded by pkg/client/clientcmd/client_builder.go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

func IsUnexpectedStatusError(err error) bool

IsUnexpectedStatusError determines if err is due to an unexpected status from the server.

func LoadTLSFiles added in v0.12.0 

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.
