Constants

const MissingGetHeader = "==> MISSING\nKIND\t\tNAME\n"

MissingGetHeader is added to Get's output when a resource is not found.

Variables

var ErrNoObjectsVisited = goerrors.New("no objects visited")

ErrNoObjectsVisited indicates that during a visit operation, no matching objects were found.

Functions

func GetConfig

func GetConfig(kubeconfig, context, namespace string) *genericclioptions.ConfigFlags

GetConfig returns a Kubernetes client config.

func IsPodReady

func IsPodReady(pod *v1.Pod) bool

IsPodReady returns true if a pod is ready; false otherwise.

func IsServiceIPSet

func IsServiceIPSet(service *v1.Service) bool

IsServiceIPSet aims to check if the service's ClusterIP is set or not the objective is not to perform validation here

Types

type Client

type Client struct {
	Factory Factory
	Log     func(string, ...interface{})
}

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

func New

func New(getter genericclioptions.RESTClientGetter) *Client

New creates a new Client.

func (*Client) Build

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

Build validates for Kubernetes objects and returns resource Infos from a io.Reader.

func (*Client) BuildUnstructured

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

BuildUnstructured validates for Kubernetes objects and returns unstructured infos.

func (*Client) Create

func (c *Client) Create(namespace string, reader io.Reader, timeout int64, shouldWait bool) 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) 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) KubernetesClientSet

func (c *Client) KubernetesClientSet() (*kubernetes.Clientset, error)

KubernetesClientSet returns a client set from the client factory.

func (*Client) Update

func (c *Client) Update(namespace string, originalReader, targetReader io.Reader, force, recreate bool, timeout int64, shouldWait bool) 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) WaitAndGetCompletedPodPhase

func (c *Client) WaitAndGetCompletedPodPhase(namespace string, reader io.Reader, timeout time.Duration) (v1.PodPhase, error)

WaitAndGetCompletedPodPhase waits up to a timeout until a pod enters a completed phase and returns said phase (PodSucceeded or PodFailed qualify).

func (*Client) WatchUntilReady

func (c *Client) WatchUntilReady(namespace string, reader io.Reader, timeout int64, shouldWait bool) 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 Factory

type Factory interface {
	// ToRawKubeConfigLoader return kubeconfig loader as-is
	ToRawKubeConfigLoader() clientcmd.ClientConfig
	// KubernetesClientSet gives you back an external clientset
	KubernetesClientSet() (*kubernetes.Clientset, error)
	// NewBuilder returns an object that assists in loading objects from both disk and the server
	// and which implements the common patterns for CLI interactions with generic resources.
	NewBuilder() *resource.Builder
	// Returns a schema that can validate objects stored on disk.
	Validator(validate bool) (validation.Schema, error)
}

Factory provides abstractions that allow the Kubectl command to be extended across multiple types of resources and different API sets.

type ResourceActorFunc

type ResourceActorFunc func(*resource.Info) error

ResourceActorFunc performs an action on a single resource.

type Result

type Result []*resource.Info

Result provides convenience methods for comparing collections of Infos.

func (*Result) Append

func (r *Result) Append(val *resource.Info)

Append adds an Info to the Result.

func (Result) Contains

func (r Result) Contains(info *resource.Info) bool

Contains checks to see if an object exists.

func (Result) Difference

func (r Result) Difference(rs Result) Result

Difference will return a new Result with objects not contained in rs.

func (Result) Filter

func (r Result) Filter(fn func(*resource.Info) bool) Result

Filter returns a new Result with Infos that satisfy the predicate fn.

func (Result) Get

func (r Result) Get(info *resource.Info) *resource.Info

Get returns the Info from the result that matches the name and kind.

func (Result) Intersect

func (r Result) Intersect(rs Result) Result

Intersect will return a new Result with objects contained in both Results.

func (Result) Visit

func (r Result) Visit(fn resource.VisitorFunc) error

Visit implements resource.Visitor.
