Functions

func ParsePath

func ParsePath(path string) (namespace string, deployment, pod string, container string, err error)

ParsePath parses path into its components. Input must have the form namespace/deployment/pod/container.

func PodKey

func PodKey(namespace, pod string) string

Types

type ResourceType

type ResourceType int

type Resources

type Resources struct {
	// Root is the first level in the cluster resource hierarchy.
	// Each level in the hierarchy is a map[string]interface{} to the next level.
	// The levels are: namespaces/deployments/pods/containers.
	Root map[string]interface{}
	// Labels maps a pod name to a map of labels key-values.
	Labels map[string]map[string]string
	// Annotations maps a pod name to a map of annotation key-values.
	Annotations map[string]map[string]string
	// Pod maps a pod name to its Pod info. The key is namespace/pod-name.
	Pod map[string]*corev1.Pod
}

Resources defines a tree of cluster resource names.
