Types

type Client

type Client struct {
	*cmdutil.Factory
}

Client represents a client capable of communicating with the Kubernetes API.

func New

func New(config clientcmd.ClientConfig) *Client

New create a new Client

func (*Client) APIClient

func (c *Client) APIClient() (unversionedclient.Interface, error)

APIClient returns a Kubernetes API client.

This is necessary because cmdutil.Client is a field, not a method, which means it can't satisfy an interface's method requirement. In order to ensure that an implementation of environment.KubeClient can access the raw API client, it is necessary to add this method.

func (*Client) Create

func (c *Client) Create(namespace string, reader io.Reader) error

Create creates kubernetes resources from an io.reader

Namespace will set the namespace

func (*Client) Delete

func (c *Client) Delete(namespace string, reader io.Reader) error

Delete deletes kubernetes resources from an io.reader

Namespace will set the namespace

func (*Client) ForwardPort

func (c *Client) ForwardPort(namespace, podName string, remote int) (*Tunnel, error)

ForwardPort opens a tunnel to a kubernetes pod

func (*Client) Get

func (c *Client) Get(namespace string, reader io.Reader) (string, error)

Get gets kubernetes resources as pretty printed string

Namespace will set the namespace

func (*Client) Update

func (c *Client) Update(namespace string, currentReader, targetReader io.Reader) error

Update reads in the current configuration and a target configuration from io.reader

and creates resources that don't already exists, updates resources that have been modified
in the target configuration and deletes resources from the current configuration that are
not present in the target configuration

Namespace will set the namespaces

func (*Client) WatchUntilReady

func (c *Client) WatchUntilReady(namespace string, reader io.Reader) error

WatchUntilReady watches the resource given in the reader, and waits until it is ready.

This function is mainly for hook implementations. It watches for a resource to hit a particular milestone. The milestone depends on the Kind.

For most kinds, it checks to see if the resource is marked as Added or Modified by the Kubernetes event stream. For some kinds, it does more:

• Jobs: A job is marked "Ready" when it has successfully completed. This is ascertained by watching the Status fields in a job's output.

Handling for other kinds will be added as necessary.

type ResourceActorFunc

type ResourceActorFunc func(*resource.Info) error

ResourceActorFunc performs an action on a single resource.

type Tunnel

type Tunnel struct {
	Local  int
	Remote int
	// contains filtered or unexported fields
}

Tunnel describes a ssh-like tunnel to a kubernetes pod

func (*Tunnel) Close

func (t *Tunnel) Close()

Close disconnects a tunnel connection
