Overview

Package unversioned 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, daemons, services, and nodes.

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

import (
  client "k8s.io/kubernetes/pkg/client/unversioned"
  "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/devel/api-conventions.md`) for a given API path and is intended for use by consumers implementing their own Kubernetes compatible APIs.

Functions

func ControllerHasDesiredReplicas 

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

ControllerHasDesiredReplicas returns a condition that will be true if and only if 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 string, groupVersion unversioned.GroupVersion, 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 DeploymentHasDesiredReplicas 

func DeploymentHasDesiredReplicas(c ExtensionsInterface, deployment *extensions.Deployment) wait.ConditionFunc

DeploymentHasDesiredReplicas returns a condition that will be true if and only if the desired replica count for a deployment equals its updated replicas count. (non-terminated pods that have the desired template spec).

func ExtractGroupVersions 

func ExtractGroupVersions(l *unversioned.APIGroupList) []string

func GetInvolvedObjectNameFieldLabel 

func GetInvolvedObjectNameFieldLabel(version string) string

Returns the appropriate field label to use for name of the involved object as per the given API version.

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 if and only if 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 JobHasDesiredParallelism 

func JobHasDesiredParallelism(c ExtensionsInterface, job *extensions.Job) wait.ConditionFunc

JobHasDesiredParallelism returns a condition that will be true if the desired parallelism count for a job equals the current active counts or is less by an appropriate successful/unsuccessful count.

func MatchesServerVersion 

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

MatchesServerVersion queries the server to compares the build version (git hash) of the client with the server's build version. It returns an error if it failed to contact the server or if the versions are not an exact match.

func NegotiateVersion 

func NegotiateVersion(client *Client, c *Config, requestedGV *unversioned.GroupVersion, clientRegisteredGVs []unversioned.GroupVersion) (*unversioned.GroupVersion, 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.

func ServerAPIVersions 

func ServerAPIVersions(c *Config) (groupVersions []string, err error)

ServerAPIVersions returns the GroupVersions supported by the API server. It creates a RESTClient based on the passed in config, but it doesn't rely on the Version, Codec, and Prefix of the config, because it uses AbsPath and takes the raw response.

func SetKubernetesDefaults 

func SetKubernetesDefaults(config *Config) error

SetKubernetesDefaults sets default values on the provided client config for accessing the Kubernetes API or returns an error if any of the defaults are impossible or invalid. TODO: this method needs to be split into one that sets defaults per group, expected to be fix in PR "Refactoring clientcache.go and helper.go #14592"

func TLSConfigFor 

func TLSConfigFor(config *Config) (*tls.Config, error)

TLSConfigFor returns a tls.Config that will provide the transport level security defined by the provided Config. Will return nil if no transport level security is requested.

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.

type RESTClient 

type RESTClient struct {

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.
