Functions

func GetConfig

func GetConfig(c *Client) (*rest.Config, error)

GetConfig returns Kubernetes config instance from the provided client

Types

type Client

type Client struct {
	// IsInCluster flags if this client points
	// to its own cluster
	IsInCluster bool

	// KubeConfigPath to get kubernetes clientset
	KubeConfigPath string
	// contains filtered or unexported fields
}

Client provides Kubernetes client operations

func Instance

func Instance(opts ...OptionFn) *Client

Instance returns a singleton instance of this client

func New

func New(opts ...OptionFn) *Client

New returns a new instance of client

func (*Client) Clientset

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

Clientset returns a new instance of Kubernetes clientset

func (*Client) Config

func (c *Client) Config() (config *rest.Config, err error)

Config returns Kubernetes config instance based on set criteria

func (*Client) ConfigForPath

func (c *Client) ConfigForPath(kubeConfigPath string) (config *rest.Config, err error)

ConfigForPath returns Kubernetes config instance based on KubeConfig path

func (*Client) Dynamic

func (c *Client) Dynamic() (dynamic.Interface, error)

Dynamic returns a kubernetes dynamic client capable of invoking operations against kubernetes resources

func (*Client) GetConfigForPathOrDirect

func (c *Client) GetConfigForPathOrDirect() (config *rest.Config, err error)

GetConfigForPathOrDirect returns Kubernetes config instance from kubeconfig path or without it

type OptionFn

type OptionFn func(*Client)

OptionFn is a typed function to abstract any operation against the provided client instance

NOTE:

This is the basic building block to create

functional operations against the client instance

func InCluster

func InCluster() OptionFn

InCluster enables IsInCluster flag

func WithKubeConfigPath

func WithKubeConfigPath(kubeConfigPath string) OptionFn

WithKubeConfigPath sets kubeconfig path against this client instance
