Types

type Client

type Client struct {
	KubeClient kubernetes.Interface
}

Client encapsulates a client for a Kubernetes cluster.

func NewClient

func NewClient(opts ...Option) (*Client, error)

NewClient builds a kubernetes client to interact with the live cluster. The kube config file path or the kubeconfig yaml must be specified If not specified, defaults are assumed - configPath: ~/.kube/config, configContext: current context

func (*Client) FetchObjects

func (c *Client) FetchObjects(ctx context.Context) (*Objects, error)

FetchObjects returns the objects from a Kubernetes cluster. ctx is currently unused during API calls. More info: https://github.com/kubernetes/community/pull/1166

type Identifier

type Identifier struct {
	Name      string
	Namespace string
}

Identifier is used to identify a specific namspace scoped object.

type Objects

type Objects struct {
	Nodes                           *corev1.NodeList
	PersistentVolumes               *corev1.PersistentVolumeList
	ComponentStatuses               *corev1.ComponentStatusList
	SystemNamespace                 *corev1.Namespace
