Functions

func GetRestConfig 

func GetRestConfig(kubeConfig, apiServerURL string) (*rest.Config, error)

GetRestConfig returns the rest clients config to get automatically data if you run inside a cluster or by passing flags.

func NewCFClient 

func NewCFClient(cfAPIEndpoint string, cfUsername string, cfPassword string) (*cfclient.Client, error)

NewCFClient return a new CF client object.

func NewCRDClientForAPIVersionKind 

func NewCRDClientForAPIVersionKind(client kubernetes.Interface, kubeConfig, apiServerURL, apiVersion, kind string) (*rest.RESTClient, *runtime.Scheme, error)

NewCRDClientForAPIVersionKind return rest client for the given apiVersion and kind of the CRD

func NewDynamicKubernetesClient 

func NewDynamicKubernetesClient(kubeConfig, apiServerURL string, requestTimeout time.Duration) (dynamic.Interface, error)

NewDynamicKubernetesClient returns a new Dynamic Kubernetes client object. It takes a Config and uses APIServerURL and KubeConfig attributes to connect to the cluster. If KubeConfig isn't provided it defaults to using the recommended default.

func NewIstioClient 

func NewIstioClient(kubeConfig string, apiServerURL string) (*istioclient.Clientset, error)

NewIstioClient returns a new Istio client object. It uses the configured KubeConfig attribute to connect to the cluster. If KubeConfig isn't provided it defaults to using the recommended default. NB: Istio controls the creation of the underlying Kubernetes client, so we have no ability to tack on transport wrappers (e.g., Prometheus request wrappers) to the client's config at this level. Furthermore, the Istio client constructor does not expose the ability to override the Kubernetes API server endpoint, so the apiServerURL config attribute has no effect.

func NewKubeClient 

func NewKubeClient(kubeConfig, apiServerURL string, requestTimeout time.Duration) (*kubernetes.Clientset, error)

NewKubeClient returns a new Kubernetes client object. It takes a Config and uses APIServerURL and KubeConfig attributes to connect to the cluster. If KubeConfig isn't provided it defaults to using the recommended default.

func NewOpenShiftClient 

func NewOpenShiftClient(kubeConfig, apiServerURL string, requestTimeout time.Duration) (*openshift.Clientset, error)

NewOpenShiftClient returns a new Openshift client object. It takes a Config and uses APIServerURL and KubeConfig attributes to connect to the cluster. If KubeConfig isn't provided it defaults to using the recommended default.
