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.

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.

func NewRequest ¶
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 ¶
AbsPath overwrites an existing path with the segments provided. Trailing slashes are preserved when a single segment is passed.
func (*Request) Body ¶
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 ¶
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) Resource ¶
Resource sets the resource to access (<resource>/[ns/<namespace>/]<name>)
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 ¶
SubResource sets a sub-resource path which can be multiple segments segment after the resource name but before the suffix.
func (*Request) Suffix ¶
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 (*Request) Timeout ¶
Timeout makes the request use the given duration as a timeout. Sets the "timeout" parameter.
func (*Request) Upgrade ¶
func (r *Request) Upgrade(config *Config, newRoundTripperFunc func(*tls.Config) httpstream.UpgradeRoundTripper) (httpstream.Connection, error)
Upgrade upgrades the request so that it supports multiplexed bidirectional streams. The current implementation uses SPDY, but this could be replaced with HTTP/2 once it's available, or something else.
type RequestConstructionError ¶
type RequestConstructionError struct {
Err error
}
RequestConstructionError is returned when there's an error assembling a request.
func (*RequestConstructionError) Error ¶
func (r *RequestConstructionError) Error() string
Error returns a textual description of 'r'.
type ResourceQuotaInterface ¶
type ResourceQuotaInterface interface { List(selector labels.Selector) (*api.ResourceQuotaList, error) Get(name string) (*api.ResourceQuota, error) Delete(name string) error Create(resourceQuota *api.ResourceQuota) (*api.ResourceQuota, error) Update(resourceQuota *api.ResourceQuota) (*api.ResourceQuota, error) UpdateStatus(resourceQuota *api.ResourceQuota) (*api.ResourceQuota, error) Watch(label labels.Selector, field fields.Selector, resourceVersion string) (watch.Interface, error) }
ResourceQuotaInterface has methods to work with ResourceQuota resources.
type ResourceQuotasNamespacer ¶
type ResourceQuotasNamespacer interface {
ResourceQuotas(namespace string) ResourceQuotaInterface
}
ResourceQuotasNamespacer has methods to work with ResourceQuota resources in a namespace
type Result ¶
type Result struct {
// contains filtered or unexported fields
}
Result contains the result of calling Request.Do().
func (Result) Error ¶
Error returns the error executing the request, nil if no error occurred. See the Request.Do() comment for what errors you might get.
func (Result) WasCreated ¶
WasCreated updates the provided bool pointer to whether the server returned 201 created or a different response.
type SecretsInterface ¶
type SecretsInterface interface { Create(secret *api.Secret) (*api.Secret, error) Update(secret *api.Secret) (*api.Secret, error) Delete(name string) error List(label labels.Selector, field fields.Selector) (*api.SecretList, error) Get(name string) (*api.Secret, error) Watch(label labels.Selector, field fields.Selector, resourceVersion string) (watch.Interface, error) }
type SecretsNamespacer ¶
type SecretsNamespacer interface {
Secrets(namespace string) SecretsInterface
}
type ServiceInterface ¶
type ServiceInterface interface { List(selector labels.Selector) (*api.ServiceList, error) Get(name string) (*api.Service, error) Create(srv *api.Service) (*api.Service, error) Update(srv *api.Service) (*api.Service, error) Delete(name string) error Watch(label labels.Selector, field fields.Selector, resourceVersion string) (watch.Interface, error) }
ServiceInterface has methods to work with Service resources.
type ServicesNamespacer ¶
type ServicesNamespacer interface {
Services(namespace string) ServiceInterface
}
ServicesNamespacer has methods to work with Service resources in a namespace
type TLSClientConfig ¶
type TLSClientConfig struct { // Server requires TLS client certificate authentication CertFile string // Server requires TLS client certificate authentication KeyFile string // Trusted root certificates for server CAFile string // CertData holds PEM-encoded bytes (typically read from a client certificate file). // CertData takes precedence over CertFile CertData []byte // KeyData holds PEM-encoded bytes (typically read from a client certificate key file). // KeyData takes precedence over KeyFile KeyData []byte // CAData holds PEM-encoded bytes (typically read from a root certificates bundle). // CAData takes precedence over CAFile CAData []byte }
TLSClientConfig contains settings to enable transport layer security
type VersionInterface ¶
type VersionInterface interface { ServerVersion() (*version.Info, error) ServerAPIVersions() (*api.APIVersions, error) }
